Reference weight = 497 + 2.54 × 675 g, in decimal grams, using the matching magnetic SAI single-rod base. A/B rod and H/N seal mass differences are unquantified, so this is not certified variant mass. Brackets, rod joints, sensors and packaging are excluded; actual weight prevails.

The 27 mm nominal cushion distance is not guaranteed usable deceleration length for a shorter stroke. Verify performance at the actual load and speed.

H means fluororubber, not 150 °C approval for the cylinder, sensors, cables or circuit.

Mounting and Rod-End Accessories

Mounting option Part code and material
LB — Axial foot mounting F-SI32LB; Low-carbon steel
FA — Front flange mounting F-SI32FA; Aluminium alloy
FB — Rear flange mounting F-SI32FA; Aluminium alloy
CA — Single rear clevis F-SE32CA; Ductile cast iron
CB — Double rear clevis F-SE32CB; Ductile cast iron
CR — Single clevis connection F-SI32CR; Ductile cast iron
TC — Intermediate trunnion mounting F-SAI32TC; Ductile cast iron
FTC — Front-cover trunnion mounting F-SI32FTC; Ductile cast iron
TCM1 — Trunnion support type 1 F-SI32TCM1; Ductile cast iron
TCM2 — Trunnion support type 2 F-SI32TCM2; Aluminium alloy

FA/FB use the same flange plate at different positions. CR requires CB. TC/FTC use matching TCM1/TCM2 supports; confirm the package and fasteners.

SAI32–125 TC is adjustable and separately orderable. The factory-fixed SAI160/200 restriction does not apply to this 32 mm cylinder. Support centers are drawing references; position for the actual load.

For this 32 mm TC bracket, locking torque is 2–3 N·m and the static holding-force reference is 800 N, not cylinder thrust or rated payload. Above this, specify factory nonstandard fixed TC. Fit and position the barrel brackets, check sloping-face contact, then pre-tighten, intermediate-tighten and finally tighten the eight black screws.

Drawing holes: LB 4 AP; FA/FB 4 BP; CR 4 K through-holes and 4 L counterbores; TCM1 4 E; TCM2 4 L through-holes and 4 K counterbores. CA DQ/CB CP tolerance: ±0.1 mm. Hole counts do not establish supplied fastener quantities.

M10 × 1.25 rod-end accessories are cataloged as carbon steel, without specifying every component or finish. Select joints and guides for the load. Their masses are excluded from bare-cylinder weight. The Y drawing does not establish a separate pin-kit code or guaranteed kit count.

Force and Application

Parameter Value
Extension effective area 804 mm²; catalog rounded single-rod area
Extension at 0.5 MPa 402 N theoretical
Retraction effective area 690 mm²; catalog rounded single-rod area
Retraction at 0.5 MPa 345 N theoretical

Theoretical axial force = effective area in mm² × pressure in MPa, before friction and losses. Rod area reduces retraction area. These are not safe working loads or guaranteed payloads.

Installation and Maintenance

Use qualified personnel. Before maintenance, secure loads, guard moving parts, isolate power/air and release residual pressure. Prevent unexpected restart motion; design for air or power loss.

Use clean, dry air filtered to 40 µm or finer; remove water, degraded oil and debris. Protect against dust, corrosion, coolant, weld spatter, vibration and heat. Prevent freezing; evaluate unusually dry air. Strong magnetic fields can affect sensing.

Start unloaded; increase load gradually. Align rod/load axes; guide against side load, bending, impact and torque. Check long-stroke buckling, sag, supports and air consumption. Rod joints do not replace guides.

General load-ratio guidelines: at most 0.7 at static/low speed, 0.5 at 50–500 mm/s and 0.3 above 500 mm/s. These are not structural safety factors or payload guarantees. Observe cylinder pressure/speed limits.

Fit flow controls at both ports. Double action commonly uses meter-out: start closed and open gradually. Adjust cushions for load/speed without forcing screws. Heavy or fast loads may need an external absorber or deceleration circuit.

Air compressibility/leakage prevent assuming precise prolonged stops with a closed-center valve or automatic multi-cylinder synchronization. Swinging links need CA/CB/TC pivots, not rigid LB mounts forced through an arc. Select flange direction/support height for the load.

Factory lubrication generally needs no added oil. If introduced, use additive-free ISO-VG32 turbine oil continuously. Catalog guide: oil mist ≤25 mg/m³ and 0.5–5 drops per 1000 L. Size the lubricator for flow; avoid excess or incompatible oil.

Clean piping; keep sealant off leading threads. Where tape is required, start 1.5–2 threads back. Verify tube pressure, temperature, OD, ID and bend radius. Hot-spatter areas may need metal or flame-resistant tubing.

Protect sliding surfaces. Periodically operate stored cylinders and prevent corrosion. Observe the lowest cylinder/fitting/valve/tube/sensor/cable limit; temperature options do not raise other component ratings.

Electrical / physical reference Limits and conditions
DMSE two-wire 10–28 V DC; 2.5–100 mA load; ≤2.8 W; internal current ≤3 mA; residual voltage ≤3.5 V; leakage ≤0.06 mA.
DMSE NPN/PNP three-wire 5–30 V DC; switching ≤30 V and ≤200 mA, capacity ≤6 W; internal current ≤5 mA; residual voltage ≤0.7 V; leakage ≤0.01 mA.
CMSE reed two-wire 5–240 V AC/DC; meet both ≤100 mA and ≤10 W. Standard residual voltage ≤2.5 V at DC 100 mA; H has no indicator or residual voltage shown. No internal/leakage current or protection circuit shown.
Frequency, shock and temperature DMSE ≤1000 Hz with reverse-polarity/surge protection; CMSE ≤200 Hz. Both: 50 G shock reference. Standard −10–70 °C; CMSE-H −10–125 °C. Sensor H does not raise the cylinder, cable or connector rating.
E-profile body dimensions DMSE length 25, height 4.7 mm; CMSE length 26.8, height 5.3 mm. Both: cross-section width 6.3, upper width 5.2 mm.

Direct-lead 020/030/050/100 means 2/3/5/10 m. M08/M12 are M8/M12 male connectors with 0.5 m lead; M08010/020/030 and M12010/020/030 have 1/2/3 m leads. Lead length is unrelated to cylinder stroke. Blank output is two-wire; N/P are NPN/PNP.

DMSE standard/A05 are IP64; W/A06 are IP68. All CMSE are IP64. A05 is flex-resistant robot cable; A06 is oil-resistant flex-resistant cable. A05/A06 are two-wire direct-lead only, with 19 mm minimum bend radius. No W quick-connector, A05/A06-W, CMSE-W, CMSE-A06 or A05-CMSE-H option is listed.

Match M8/M12 and B two-wire/C three-wire female leads to the sensor. Two-wire pins: 1 brown (+), 4 blue (−), 3 unused. Three-wire: 1 brown (+), 3 blue (−), 4 black output. Direct leads need no quick mating cable. Independent cable temperature, IP and voltage ratings are not given; do not transfer sensor-body ratings to the complete assembly.

For three-wire NPN put the load between positive and black output; for PNP between black output and negative. Check residual voltage and leakage for PLC inputs and series/parallel circuits; simultaneous series sensing lights the LEDs together, not a universal PLC compatibility guarantee.

Insert E-profile sensor into the matching cylinder groove with its screw clear of the bottom face; position near the middle of the switching range, then tighten. Recommended locking torque 0.15–0.20 N·m; never exceed 0.25 N·m.

Connect the correct load and supply before energizing; two-wire sensors must not be placed directly across the supply without a load. Keep leads insulated and separate from high-voltage/power wiring; prevent repeated strain, impact and strong magnetic interference.

Inspect sensor fixing, cable condition and indication periodically. Waterproof versions are not a guarantee for prolonged immersion; protect against oil, chemicals, weld spatter, rapid temperature cycling and dense magnetic material as required.

H cylinder seal code and CMS sensor H suffix are separate options. The SAI/SAIJ general published cylinder range is −20 to 70 °C; no independently established full H cylinder range is supplied here. Apply the limits of the actual cylinder, selected sensor, cable and connectors together.

These are separately selected alternatives, not a supplied kit or stock promise. Match actual NPT1/8 cylinder working ports, sealing method, insertion depth, wrench/rotation clearance, flow and tube loading. PT, G and NPT are not interchangeable. The M10 × 1.25 rod thread is not an air port. Marked discontinued families, including NPSS, are historical/installed-equipment references only: confirm remaining availability or an approved replacement before ordering, not current standard supply.

Use suitable soft nylon or PU tubing with the exact inch OD; compression fittings also require the listed ID. 5/32, 1/4, 5/16 and 3/8 in are 3.96875, 6.35, 7.9375 and 9.525 mm, not nominal metric tube sizes. NPHF has male RA and additional female RB, both NPT1/8: connect or seal RB as the circuit permits; it is not a tube socket. Tees, crosses and distribution fittings must not bridge chambers or unrelated controls. NPKD uses main 1/4 in and branch 5/32 in OD.

Ordinary push-in fittings and listed flow controls are rated 0–1 MPa, −20–70 °C. NBPC/NBKC/NBB/NBZ are 0–1 MPa, 0–150 °C, limiting H pressure to 0.15–1 MPa; actual H temperature and lower component limits apply. NBPC does not share the metric BPC 0.9 MPa limit. A component vacuum rating does not approve a vacuum cylinder assembly.

NBKC5/32-3/32-1/8 follows the explicit model/dimension row; a conflicting equal-OD/ID selection-matrix row requires procurement confirmation. Hold the body hex for thread installation, not the tube-locking nut; insert tubing fully and tighten correctly. NBB has two male NPT ends; match the separately labelled second end to a female component. NBZ closes only permitted unused auxiliary connections, never either active cylinder working port.

At the cylinder, A restricts cylinder/thread → tube exhaust (meter-out), with free reverse supply; B restricts tube → cylinder supply (meter-in). A is the usual double-acting exhaust-control choice; B needs a designed meter-in circuit. Start closed and open slowly; these are not safety isolation. NPTL1/8 maximum cap-adjustment torque is 0.08 N·m, not pipe-thread torque. Do not force end stops or use pliers. NPSA is an inch tube-to-tube control without A/B suffixes: match both ODs and the body flow symbol.

NBSL/NBSLM/NBESL are only for a separately selected valve exhaust with matching NPT1/8 thread, adequate flow and acceptable backpressure. They are not cylinder working-port parts, inlet filters or shutoffs; NBESL adjustment changes backpressure. ASC10006T has two female NPT1/8 ports and needs separate male connections; follow its P/A and check/throttle symbol. Its 0.05–0.95 MPa, −20–70 °C limits the SAI path to 0.15–0.95 MPa before other limits.

GAFR20006ST is a separate upstream NPT1/8 filter/regulator: inlet ≤1 MPa, setting 0.15–0.9 MPa, −5–70 °C non-freezing. Check flow, pressure drop, condensate, bowl environment and all downstream limits. It is not a cylinder-mounted fitting or vacuum regulator. Metric PU coils, PSA/GPSA and PPA are not specified for these inch sockets; select separately verified inch tubing and connections. No complete inch-tube coil ordering code is established here.

Separate Directional-Valve and Tube Examples

The SAI32 NPT1/8 cylinder can be controlled through a correctly designed separate pneumatic circuit. The independently verified directional-valve examples below have PT/G ports, not NPT: 5V11006B050, 5V12006B050, 5V21006B050, 5V22006B050, 4V11006B, 4V11006BG, 4V12006B, 4V12006BG, 4V21006B, 4V21006BG, 4V22006B, 4V22006BG, 4A11006, 4A11006G, 4A12006, 4A12006G, 4A21006, 4A21006G, 4A22006, 4A22006G. Match valve-side and cylinder-side fittings and tubing separately; a complete mixed-thread connection kit is not established by these examples. Separate circuit examples; no speed guarantee. B means DC24V; cylinder SKU does not select voltage. 10/20 are single/double actuation. Listed 5V uses 050 (0.5 m leads), internal pilot and PT ports only; no G or NPT 5V code is inferred. Listed 4V uses default DIN entry and internal pilot; I flying-lead or -W external-pilot variants are not these examples. 4A needs independent pneumatic pilot commands, no coil voltage; verify pilot-port thread and pilot-air supply. The listed valve limit is 0.15–0.8 MPa with 40 µm filtered air, below the cylinder maximum of 1.0 MPa. Verify switching logic; apply the circuit conditions below.

Blue 100 m coil examples: PA6060040100MBU (PA6, 6×4 mm, -10 to 70°C,3 MPa at 23°C,min bend 45 mm); PA12060040100MBU (PA12, 6×4 mm, -40 to 70°C,2 MPa at 23°C,min bend 35 mm); UN54D060040100MBU (flame-resistant, 6×4 mm, -20 to 70°C,1 MPa at 23°C,min bend 12 mm); UN54D080050100MBU (flame-resistant, 8×5 mm, -20 to 70°C,1 MPa at 23°C,min bend 18 mm). Derate pressure for temperature; select compatible fittings and length. Coils are not supplied cut lengths. No reviewed nylon 8×5 mm option; 8×6 is different. Flame resistance is not a fireproof-system claim.

M5 chart entries are separate valve connections, not SAI cylinder ports. 4M needs NAMUR; no SAI mounting/adapter compatibility is established.

The PA/UN examples are metric tubing references, not matches for the reviewed inch NPT fitting sockets. Do not equate 6 mm with 1/4 inch or 8 mm with 5/16 inch; choose a separately verified complete tube/fitting chain.

Generic bore-based circuit references, not measured SAI32 speeds. Flow area is neither piston area nor rated valve flow. Pressure, tube length and load are unspecified; the 0.5 MPa force example does not apply. Design for actual valve flow, fittings, tubing, cushioning, exhaust backpressure and the 30–800 mm/s cylinder limit. Similar nominal sizes do not make metric tubes fit inch sockets.

    Mounting and Rod-End Accessories

    Mounting option Part code and material
    LB — Axial foot mounting F-SI32LB; Low-carbon steel
    FA — Front flange mounting F-SI32FA; Aluminium alloy
    FB — Rear flange mounting F-SI32FA; Aluminium alloy
    CA — Single rear clevis F-SE32CA; Ductile cast iron
    CB — Double rear clevis F-SE32CB; Ductile cast iron
    CR — Single clevis connection F-SI32CR; Ductile cast iron
    TC — Intermediate trunnion mounting F-SAI32TC; Ductile cast iron
    FTC — Front-cover trunnion mounting F-SI32FTC; Ductile cast iron
    TCM1 — Trunnion support type 1 F-SI32TCM1; Ductile cast iron
    TCM2 — Trunnion support type 2 F-SI32TCM2; Aluminium alloy

    FA/FB use the same flange plate at different positions. CR requires CB. TC/FTC use matching TCM1/TCM2 supports; confirm the package and fasteners.

    SAI32–125 TC is adjustable and separately orderable. The factory-fixed SAI160/200 restriction does not apply to this 32 mm cylinder. Support centers are drawing references; position for the actual load.

    For this 32 mm TC bracket, locking torque is 2–3 N·m and the static holding-force reference is 800 N, not cylinder thrust or rated payload. Above this, specify factory nonstandard fixed TC. Fit and position the barrel brackets, check sloping-face contact, then pre-tighten, intermediate-tighten and finally tighten the eight black screws.

    Drawing holes: LB 4 AP; FA/FB 4 BP; CR 4 K through-holes and 4 L counterbores; TCM1 4 E; TCM2 4 L through-holes and 4 K counterbores. CA DQ/CB CP tolerance: ±0.1 mm. Hole counts do not establish supplied fastener quantities.

    M10 × 1.25 rod-end accessories are cataloged as carbon steel, without specifying every component or finish. Select joints and guides for the load. Their masses are excluded from bare-cylinder weight. The Y drawing does not establish a separate pin-kit code or guaranteed kit count.

    Force and Application

    Parameter Value
    Extension effective area 804 mm²; catalog rounded single-rod area
    Extension at 0.5 MPa 402 N theoretical
    Retraction effective area 690 mm²; catalog rounded single-rod area
    Retraction at 0.5 MPa 345 N theoretical

    Theoretical axial force = effective area in mm² × pressure in MPa, before friction and losses. Rod area reduces retraction area. These are not safe working loads or guaranteed payloads.

    Installation and Maintenance

    Use qualified personnel. Before maintenance, secure loads, guard moving parts, isolate power/air and release residual pressure. Prevent unexpected restart motion; design for air or power loss.

    Use clean, dry air filtered to 40 µm or finer; remove water, degraded oil and debris. Protect against dust, corrosion, coolant, weld spatter, vibration and heat. Prevent freezing; evaluate unusually dry air. Strong magnetic fields can affect sensing.

    Start unloaded; increase load gradually. Align rod/load axes; guide against side load, bending, impact and torque. Check long-stroke buckling, sag, supports and air consumption. Rod joints do not replace guides.

    General load-ratio guidelines: at most 0.7 at static/low speed, 0.5 at 50–500 mm/s and 0.3 above 500 mm/s. These are not structural safety factors or payload guarantees. Observe cylinder pressure/speed limits.

    Fit flow controls at both ports. Double action commonly uses meter-out: start closed and open gradually. Adjust cushions for load/speed without forcing screws. Heavy or fast loads may need an external absorber or deceleration circuit.

    Air compressibility/leakage prevent assuming precise prolonged stops with a closed-center valve or automatic multi-cylinder synchronization. Swinging links need CA/CB/TC pivots, not rigid LB mounts forced through an arc. Select flange direction/support height for the load.

    Factory lubrication generally needs no added oil. If introduced, use additive-free ISO-VG32 turbine oil continuously. Catalog guide: oil mist ≤25 mg/m³ and 0.5–5 drops per 1000 L. Size the lubricator for flow; avoid excess or incompatible oil.

    Clean piping; keep sealant off leading threads. Where tape is required, start 1.5–2 threads back. Verify tube pressure, temperature, OD, ID and bend radius. Hot-spatter areas may need metal or flame-resistant tubing.

    Protect sliding surfaces. Periodically operate stored cylinders and prevent corrosion. Observe the lowest cylinder/fitting/valve/tube/sensor/cable limit; temperature options do not raise other component ratings.

    Electrical / physical reference Limits and conditions
    DMSE two-wire 10–28 V DC; 2.5–100 mA load; ≤2.8 W; internal current ≤3 mA; residual voltage ≤3.5 V; leakage ≤0.06 mA.
    DMSE NPN/PNP three-wire 5–30 V DC; switching ≤30 V and ≤200 mA, capacity ≤6 W; internal current ≤5 mA; residual voltage ≤0.7 V; leakage ≤0.01 mA.
    CMSE reed two-wire 5–240 V AC/DC; meet both ≤100 mA and ≤10 W. Standard residual voltage ≤2.5 V at DC 100 mA; H has no indicator or residual voltage shown. No internal/leakage current or protection circuit shown.
    Frequency, shock and temperature DMSE ≤1000 Hz with reverse-polarity/surge protection; CMSE ≤200 Hz. Both: 50 G shock reference. Standard −10–70 °C; CMSE-H −10–125 °C. Sensor H does not raise the cylinder, cable or connector rating.
    E-profile body dimensions DMSE length 25, height 4.7 mm; CMSE length 26.8, height 5.3 mm. Both: cross-section width 6.3, upper width 5.2 mm.

    Direct-lead 020/030/050/100 means 2/3/5/10 m. M08/M12 are M8/M12 male connectors with 0.5 m lead; M08010/020/030 and M12010/020/030 have 1/2/3 m leads. Lead length is unrelated to cylinder stroke. Blank output is two-wire; N/P are NPN/PNP.

    DMSE standard/A05 are IP64; W/A06 are IP68. All CMSE are IP64. A05 is flex-resistant robot cable; A06 is oil-resistant flex-resistant cable. A05/A06 are two-wire direct-lead only, with 19 mm minimum bend radius. No W quick-connector, A05/A06-W, CMSE-W, CMSE-A06 or A05-CMSE-H option is listed.

    Match M8/M12 and B two-wire/C three-wire female leads to the sensor. Two-wire pins: 1 brown (+), 4 blue (−), 3 unused. Three-wire: 1 brown (+), 3 blue (−), 4 black output. Direct leads need no quick mating cable. Independent cable temperature, IP and voltage ratings are not given; do not transfer sensor-body ratings to the complete assembly.

    For three-wire NPN put the load between positive and black output; for PNP between black output and negative. Check residual voltage and leakage for PLC inputs and series/parallel circuits; simultaneous series sensing lights the LEDs together, not a universal PLC compatibility guarantee.

    Insert E-profile sensor into the matching cylinder groove with its screw clear of the bottom face; position near the middle of the switching range, then tighten. Recommended locking torque 0.15–0.20 N·m; never exceed 0.25 N·m.

    Connect the correct load and supply before energizing; two-wire sensors must not be placed directly across the supply without a load. Keep leads insulated and separate from high-voltage/power wiring; prevent repeated strain, impact and strong magnetic interference.

    Inspect sensor fixing, cable condition and indication periodically. Waterproof versions are not a guarantee for prolonged immersion; protect against oil, chemicals, weld spatter, rapid temperature cycling and dense magnetic material as required.

    H cylinder seal code and CMS sensor H suffix are separate options. The SAI/SAIJ general published cylinder range is −20 to 70 °C; no independently established full H cylinder range is supplied here. Apply the limits of the actual cylinder, selected sensor, cable and connectors together.

    These are separately selected alternatives, not a supplied kit or stock promise. Match actual NPT1/8 cylinder working ports, sealing method, insertion depth, wrench/rotation clearance, flow and tube loading. PT, G and NPT are not interchangeable. The M10 × 1.25 rod thread is not an air port. Marked discontinued families, including NPSS, are historical/installed-equipment references only: confirm remaining availability or an approved replacement before ordering, not current standard supply.

    Use suitable soft nylon or PU tubing with the exact inch OD; compression fittings also require the listed ID. 5/32, 1/4, 5/16 and 3/8 in are 3.96875, 6.35, 7.9375 and 9.525 mm, not nominal metric tube sizes. NPHF has male RA and additional female RB, both NPT1/8: connect or seal RB as the circuit permits; it is not a tube socket. Tees, crosses and distribution fittings must not bridge chambers or unrelated controls. NPKD uses main 1/4 in and branch 5/32 in OD.

    Ordinary push-in fittings and listed flow controls are rated 0–1 MPa, −20–70 °C. NBPC/NBKC/NBB/NBZ are 0–1 MPa, 0–150 °C, limiting H pressure to 0.15–1 MPa; actual H temperature and lower component limits apply. NBPC does not share the metric BPC 0.9 MPa limit. A component vacuum rating does not approve a vacuum cylinder assembly.

    NBKC5/32-3/32-1/8 follows the explicit model/dimension row; a conflicting equal-OD/ID selection-matrix row requires procurement confirmation. Hold the body hex for thread installation, not the tube-locking nut; insert tubing fully and tighten correctly. NBB has two male NPT ends; match the separately labelled second end to a female component. NBZ closes only permitted unused auxiliary connections, never either active cylinder working port.

    At the cylinder, A restricts cylinder/thread → tube exhaust (meter-out), with free reverse supply; B restricts tube → cylinder supply (meter-in). A is the usual double-acting exhaust-control choice; B needs a designed meter-in circuit. Start closed and open slowly; these are not safety isolation. NPTL1/8 maximum cap-adjustment torque is 0.08 N·m, not pipe-thread torque. Do not force end stops or use pliers. NPSA is an inch tube-to-tube control without A/B suffixes: match both ODs and the body flow symbol.

    NBSL/NBSLM/NBESL are only for a separately selected valve exhaust with matching NPT1/8 thread, adequate flow and acceptable backpressure. They are not cylinder working-port parts, inlet filters or shutoffs; NBESL adjustment changes backpressure. ASC10006T has two female NPT1/8 ports and needs separate male connections; follow its P/A and check/throttle symbol. Its 0.05–0.95 MPa, −20–70 °C limits the SAI path to 0.15–0.95 MPa before other limits.

    GAFR20006ST is a separate upstream NPT1/8 filter/regulator: inlet ≤1 MPa, setting 0.15–0.9 MPa, −5–70 °C non-freezing. Check flow, pressure drop, condensate, bowl environment and all downstream limits. It is not a cylinder-mounted fitting or vacuum regulator. Metric PU coils, PSA/GPSA and PPA are not specified for these inch sockets; select separately verified inch tubing and connections. No complete inch-tube coil ordering code is established here.

    Separate Directional-Valve and Tube Examples

    The SAI32 NPT1/8 cylinder can be controlled through a correctly designed separate pneumatic circuit. The independently verified directional-valve examples below have PT/G ports, not NPT: 5V11006B050, 5V12006B050, 5V21006B050, 5V22006B050, 4V11006B, 4V11006BG, 4V12006B, 4V12006BG, 4V21006B, 4V21006BG, 4V22006B, 4V22006BG, 4A11006, 4A11006G, 4A12006, 4A12006G, 4A21006, 4A21006G, 4A22006, 4A22006G. Match valve-side and cylinder-side fittings and tubing separately; a complete mixed-thread connection kit is not established by these examples. Separate circuit examples; no speed guarantee. B means DC24V; cylinder SKU does not select voltage. 10/20 are single/double actuation. Listed 5V uses 050 (0.5 m leads), internal pilot and PT ports only; no G or NPT 5V code is inferred. Listed 4V uses default DIN entry and internal pilot; I flying-lead or -W external-pilot variants are not these examples. 4A needs independent pneumatic pilot commands, no coil voltage; verify pilot-port thread and pilot-air supply. The listed valve limit is 0.15–0.8 MPa with 40 µm filtered air, below the cylinder maximum of 1.0 MPa. Verify switching logic; apply the circuit conditions below.

    Blue 100 m coil examples: PA6060040100MBU (PA6, 6×4 mm, -10 to 70°C,3 MPa at 23°C,min bend 45 mm); PA12060040100MBU (PA12, 6×4 mm, -40 to 70°C,2 MPa at 23°C,min bend 35 mm); UN54D060040100MBU (flame-resistant, 6×4 mm, -20 to 70°C,1 MPa at 23°C,min bend 12 mm); UN54D080050100MBU (flame-resistant, 8×5 mm, -20 to 70°C,1 MPa at 23°C,min bend 18 mm). Derate pressure for temperature; select compatible fittings and length. Coils are not supplied cut lengths. No reviewed nylon 8×5 mm option; 8×6 is different. Flame resistance is not a fireproof-system claim.

    M5 chart entries are separate valve connections, not SAI cylinder ports. 4M needs NAMUR; no SAI mounting/adapter compatibility is established.

    The PA/UN examples are metric tubing references, not matches for the reviewed inch NPT fitting sockets. Do not equate 6 mm with 1/4 inch or 8 mm with 5/16 inch; choose a separately verified complete tube/fitting chain.

    Circuit-Sizing Reference

    Theoretical reference speed Flow-area and tube reference
    300 mm/s 1.3 mm² effective flow area; 6 × 4 mm tube OD × ID
    400 mm/s 1.7 mm² effective flow area; 6 × 4 mm tube OD × ID
    500 mm/s 2.1 mm² effective flow area; 6 × 4 mm tube OD × ID
    600 mm/s 2.5 mm² effective flow area; 8 × 5 mm tube OD × ID
    700 mm/s 2.9 mm² effective flow area; 8 × 5 mm tube OD × ID
    800 mm/s 3.4 mm² effective flow area; 8 × 5 mm tube OD × ID

    Generic bore-based circuit references, not measured SAI32 speeds. Flow area is neither piston area nor rated valve flow. Pressure, tube length and load are unspecified; the 0.5 MPa force example does not apply. Design for actual valve flow, fittings, tubing, cushioning, exhaust backpressure and the 30–800 mm/s cylinder limit. Similar nominal sizes do not make metric tubes fit inch sockets.
