Features and load limits
The two piston rods resist bending and twisting and provide a fixing plate with workpiece mounting from three directions. Body mounting is available from multiple faces.
The twin-piston force table uses twice the single-piston working area. Select force with a load margin and check side-load capacity separately.
The permitted side load decreases with stroke. The TN diagram gives load in newtons; the TR horizontal/vertical diagrams and unloaded-tip deflection diagram must be read using their respective units and mounting positions.
For non-standard strokes within100 mm in5 mm steps, the next longer standard-stroke body is used:35 mm has the40 mm external envelope. This does not change the ordered working stroke.

Position sensing
The dedicated product and sensor selection tables specify J-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 M5 × 0.8; a reference accessory with a different thread is not a direct screw-in connection.

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. A final -H on a CMS order code selects the high-temperature reed version.
CMSJ 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 DMSJ 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 DMSJ 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 has a recommended minimum bend radius of 19 mm. These are two-wire direct-lead types, without M8/M12, NPN/PNP or W options; A05-CMS also excludes the final high-temperature -H suffix. W means waterproof; DMS-W has direct leads only. DMSJ is not available with A06 cable.
Sensor temperature limits are −10 to +70°C, or −10 to +125°C for CMS versions with the final -H suffix. The TN cylinder remains limited to +70°C. Ordinary, high-temperature and A05 sensors are IP64; W versions are IP68. These ratings do not extend to the cylinder, connectors or whole assembly; use their common limits.
CMS has no protection circuit; DMS has reverse-polarity and surge 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 sensor in its matching switch groove. For a J-profile sensor, loosen the screw enough to let its lower mounting piece enter the groove. Slide it 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.
Optional air connections, tubing and controls
For the 6 mm OD tubing in the circuit reference in this description, choose a straight fitting or an A-type controller at each cylinder port. Use straight fittings at the valve A/B ports and keep the two chamber lines separate.

The A-type controller restricts flow from the cylinder port to the tube; reverse flow is free. Recommended cap-rotation torque is 0.05 N·m, not thread-tightening torque. Seat the M5 sealing gaskets correctly.
The listed gray fittings and controllers accept soft nylon or polyurethane tubing and are rated for 0–1 MPa and −20 to +70°C. Check tube insertion, wrench clearance and every connected part’s limits.
The 5V110 codes are single-solenoid spring-return valves; 5V120 codes are double-solenoid valves with memory. The final 050 or 200 selects a 0.5 m or 2 m terminal cable as part of the complete valve configuration. AC versions use 2.0 VA with +15%/−10% voltage tolerance; DC versions use 1.6 W with ±10% tolerance. These terminal-cable valves have dust protection; they are not DIN-plug versions.
The existing 4A110M5 and 4A120M5 pneumatic alternatives need one or two external pilot signals respectively through separate PT1/8 pilot ports. The listed pilot connection assumes 6 mm OD pilot tubing; match both ends of the pilot line and the actual control signal. Seal the tapered PT pilot threads with suitable thread sealant. Use only the chosen electrical or pneumatic control scheme.
With either listed valve family, the working circuit is limited to 0.15–0.8 MPa and −20 to +70°C, subject to any lower component limit.
BSLM5 fits the selected M5×0.8 valve exhaust ports R/S; do not fit it to cylinder working ports. Silencer limits are 0–1 MPa and −20 to +70°C.
The blue 100 m tube codes are purchasable packaging examples, not the required installed tube length. US98A is polyester polyurethane (−20 to +70°C); UE95A is polyether polyurethane (−40 to +70°C). Both listed standard sizes are rated to 1 MPa at 23°C; apply temperature derating and the lowest limit of the whole circuit. Avoid solvents, corrosive media and prolonged direct sunlight. Minimum bend radii for US98A/UE95A are 15/12 mm.Weight reference
