Mpo/Myo/Mro apply at the end of travel; Mp/My/Mr apply during travel. Compensation distances A/B/C in this load table are separate from body-dimension callouts with the same letters. Check the combined ratios Mp/Mpmax + My/Mymax + Mr/Mrmax ≤ 1, and separately Mpo/Mpomax + Myo/Myomax + Mro/Mromax ≤ 1.
The catalog selection method uses E = 0.5 × (W/g) × (1.4 Va/1000)², with W in newtons, g = 9.81 m/s² and average speed Va in mm/s. Require E ≤ K × Emax and W ≤ K × β × Wmax. K is 1.0 for a top-mounted fixture and 0.6 for a front-mounted fixture; β is read from the speed-dependent load graph. Check actual offsets and all three moments, including stopping inertia. The catalog acceleration model is a = 1600(Va/1000)² with fixed cushioning or 400(Va/1000)² with hydraulic cushioning.
For horizontal mounting, the catalog uses Mp = W(L1+A)/1000 and Mpo = Mp + Wa(L2+B)/(1000g). The transverse moment arm includes the guide offset C, giving C+L3. For vertical mounting, use the separate vertical formulas and add inertia to the static moment at the stroke end. The load/deflection graphs distinguish pitch, yaw and roll and the illustrated stroke; they do not promise zero deflection or one universal payload. The roll-deflection reference arm Lr for this bore is 122 mm.

Keep screw penetration at least 0.5 mm below the maximum depth and within the actual detailed drawing. Mounting-table maxima do not override a shallower tapped hole shown in a particular view.
Support the slide table while tightening fixture screws; holding only the body can transmit tightening torque into the guide and reduce accuracy.
Maintain at least 3 mm separation from an adjacent magnetic cylinder to avoid sensor interference. Check all fixture clearances throughout travel.
Use the selected symmetric or standard drawing for port access and stop placement. Begin flow adjustment slowly and remain within the energy, load and moment limits.

Assembly
Series selection
The standard strokes for the 20 mm bore are 10, 20, 30, 40, 50, 75, 100, 125, 150 mm. Options are fixed cushioning, A/AS/AF adjustable stops and B/BS/BF hydraulic shock absorbers. The option suffix identifies the equipped end(s). M5 ports apply to bores 6–16 mm; PT, G or NPT 1/8 choices are listed for bores 20/25 mm. Other bores or strokes require a specifically defined order.
Position sensing
The dedicated product and sensor selection tables specify H (CMSH / DMSH / EMSH)-profile magnetic sensors for this series and size. Select the full sensor order code separately for the required output, voltage, cable and connector; the profile letter does not identify the electrical specification. Sensor switches and separately ordered holders are not included unless the product configuration expressly lists them.
Pneumatic circuit selection reference
The 2022 selection example for a 20 mm cylinder bore uses a theoretical speed of 500 mm/s and an effective flow area of 0.8 mm². It is a circuit-sizing example, not a guaranteed installed speed or a supplied package. Match the actual cylinder port, valve capacity and tubing. This product uses PT 1/8; a reference accessory with a different thread is not a direct screw-in connection.

This slide uses a twin-piston drive. The general single-cylinder circuit example is only an initial reference; size the actual flow supply for the complete actuator and required cycle time.
Installation and operating conditions
Flush the piping before connection and use clean, conditioned compressed air with the filtration specified for this cylinder. Keep sealant clear of the first 1–2 thread turns.
Align the actuator and load; provide protection from moving parts and unexpected motion after a loss or restoration of air or electrical power. Exhaust residual pressure before maintenance or removal.
Start with the flow-control valve closed and open gradually to the required speed. Check cushioning against the actual speed, load and stopping energy; a closed-center valve does not guarantee prolonged load holding or precise intermediate stopping.
Protect the sliding surfaces, prevent moisture from freezing and keep contaminants out of the ports. Protect stored equipment from corrosion. Follow the dedicated lubrication instructions; where continued lubrication is selected, the general catalog specifies additive-free ISO VG32 turbine oil.

Two-wire mating cables (B)For a matching M8 or M12 two-wire male sensor; ordered separately.F-ECM08B020, F-ECM08B030, F-ECM08B050, F-ECM08B100, F-ECM12B020, F-ECM12B030, F-ECM12B050, F-ECM12B100
Three-wire mating cables (C)For a matching M8 or M12 NPN/PNP male sensor; ordered separately.F-ECM08C020, F-ECM08C030, F-ECM08C050, F-ECM08C100, F-ECM12C020, F-ECM12C030, F-ECM12C050, F-ECM12C100
The listed options are alternatives, not a required set. The H in CMSH/DMSH/EMSH identifies the sensor profile; a final -H on a CMS order code instead selects the high-temperature reed version.
CMSH reed sensors are limited to 100 mA, 10 W and 200 Hz, with no internal consumption or leakage. Standard/A05 voltage drop is at most 2.5 V at 100 mA DC; versions with the final -H suffix have no residual voltage or indicator LED.
Two-wire DMSH and EMSH require 2.5–100 mA loads, up to 2.8 W and 1,000 Hz. Maximum consumption, residual voltage and leakage are 3 mA, 3.5 V and 0.06 mA respectively.
NPN/PNP DMSH outputs are rated to 30 V / 200 mA, 6 W and 1,000 Hz. Maximum consumption, residual voltage and leakage are 5 mA, 0.7 V and 0.01 mA respectively. Check controller input compatibility as well as load ratings.
Sensor and female-cable endings 020/030/050/100 mean 2/3/5/10 m. M08/M12 sensors have M8/M12 male connectors on 0.5 m leads; M08010/M08020/M08030 and M12010/M12020/M12030 give 1/2/3 m leads. Lead length does not depend on cylinder stroke.
Match female cables to the male connector size and wire count; direct-lead sensors need none. B pinout: 1 brown (+), 4 blue (−), 3 unused. C pinout: 1 brown (+), 3 blue (−), 4 black output. Check the mating cable and connector ratings separately.
A05 flex-resistant robotics cable and A06 oil-resistant flex cable have a recommended minimum bend radius of 19 mm. Both are two-wire direct-lead types, without M8/M12, NPN/PNP or W options; A05-CMSH also excludes the final high-temperature -H suffix. W means waterproof: DMSH-W has direct leads only; the listed EMSH-W options also include connectors.
Sensor temperature limits are −10 to +70°C, or −10 to +125°C for CMSH versions with the final -H suffix. The HLS cylinder remains limited to +70°C. Ordinary, high-temperature and A05 sensors are IP64; W/A06 are IP68. These ratings do not extend to the cylinder, connectors or whole assembly; use their common limits.
CMS has no protection circuit; DMS/EMS have reverse-polarity and surge protection, and EMS also has temperature-overload protection. Reed, two-wire electronic, NPN and PNP circuits are not interchangeable. Complete and insulate wiring before powering it; keep it separate from power/high-voltage wiring. For direct leads, connect brown and blue in series with the load on two-wire types; do not connect the switch alone across the supply. On three-wire types, brown is positive supply, blue is negative and black is output; connect an NPN load to positive and a PNP load to negative.
Install the selected H-profile sensor in a matching sensor groove on the HLS cylinder body. Detection uses the magnet included in this S configuration. Loosen the locking screw so it does not project below the sensor base. Slide the sensor to the required position, then tighten. Set detection at the actuation-range centre. Recommended sensor-screw torque is 0.15–0.20 N·m, never over 0.25 N·m; these are not cylinder mounting torques. Prevent impacts; keep cables free of strain and avoid unnecessary movement or bending. Observe the stated bend-radius guidance for flex-resistant versions, and inspect fixings, cables and indication.
Keep ordinary sensors dry and do not immerse waterproof types for long periods. Avoid explosive gas, aggressive chemicals, sudden temperature changes, welding interference and magnetic debris. Provide suitable protection for A05 cables exposed to heat, dust, water or oil, and for A06 cables exposed to weld spatter.
Optional air connections, tubing and controls
Choose the listed straight fitting or A-type controller at each PT1/8 cylinder chamber port and the specified straight fittings at the separate valve A/B ports; keep both chamber lines separate. The A-type restricts cylinder-to-tube exhaust and permits free charging.

Fittings/controllers accept exact 6 mm OD soft nylon/PU tubing at 0–1 MPa and −20 to +70°C. Recommended cap-rotation torque is 0.08 N·m, not thread-tightening torque. Seal tapered PT connections correctly. Seat the M5 valve-side gasket correctly.
5V110 is single-solenoid spring return; 5V120 is double-solenoid with memory. Final 050/200 selects a 0.5/2 m terminal cable, not a DIN plug. AC tolerance is +15%/−10% (2.0 VA); DC is ±10% (1.6 W). Select the electrical or pneumatic control scheme.
The existing 4A110M5/4A120M5 pneumatic alternatives require one/two external pilot signals through separate PT1/8 pilot ports. The listed pilot fitting assumes 6 mm OD pilot tubing; match both ends and seal the tapered pilot thread.
The selected 5V/4A control branch is limited to 0.15–0.7 MPa and −20 to +70°C, subject to temperature derating and the lowest connected-component limit.
BSLM5 fits these selected valve exhaust ports R/S (M5×0.8), not cylinder work ports. Silencer limits are 0–1 MPa and −20 to +70°C.
The two blue 100 m tube codes are alternative packaging examples, not required installed lengths. US98A polyester-PU is rated −20 to +70°C; UE95A polyether-PU −40 to +70°C. Both are rated 1 MPa at 23°C; minimum bend radii (US/UE) are 15/12 mm. Apply temperature derating and the lowest component limit; avoid solvents, corrosive media and prolonged sunlight.Weight reference
1154 g; an estimate using the same bore/stroke base cylinder. The published body weight does not separately include the selected accessory or port-thread variant, so this is not an official measured weight of the full configured assembly. The catalog lists the symmetric layout with the corresponding standard family. Actual product weight governs; this is not a packed shipping weight.
