The 2022 selection information for HFT32 lists H profile: CMSH / DMSH / EMSH. Select the full sensor code for the required output, supply voltage, cable length and connector. Sensors are ordered separately; a matching mounting profile alone does not specify the electrical configuration.
Gripping-force and gripping-point selection
Select effective gripping force for the actual air pressure, jaw contact position and friction. The catalog uses F ≥ a × m × g / (n × μ), where F is force per jaw, n is the number of contacting jaws, μ is the attachment/workpiece friction coefficient, m is workpiece mass and g = 9.8 m/s². With two jaws and safety factor a = 4, μ = 0.2 requires approximately 10 × m × g per jaw and μ = 0.1 requires 20 × m × g. Allow a larger safety margin for high acceleration or impact; even at higher friction the catalog retains the conservative 10–20 times guideline.
Choose the opening span to fit the workpiece, then check the force curve for the exact bore and stroke group. The gripping position is R in mm. Short and long stroke groups have different curves, even at the same bore. Keep fingers short and light and stay within the graphed force range.
Dimensions for this configuration
Linear drawing dimensions are in mm unless a thread or angle is stated. Letter labels retain their meaning in the corresponding catalog view. Only the current action and attachment form are selected; parenthesized single-acting values from the source are resolved to this model.

The mounting method names above refer to cylinder-body attachment. Jaw suffix B, N, F, R, W or M describes the separate jaw attachment geometry. Use the dimensions of the selected jaw rather than treating these suffixes as a body-mount kit.
Installation and safe operation
- Install a workpiece fall-prevention device wherever loss of circuit pressure could release the load. Do not rely on gripping force alone to keep a suspended part safe.
- Prevent excessive external force, side load, impact and collision at the end of jaw or machine travel. Leave clearance around the workpiece and attachments throughout opening, transfer and reversal.
- Keep custom fingers short and light. Align the workpiece with the jaw centerline, and make both contact surfaces engage together where the two-jaw arrangement is used. Do not use the gripper to force an off-center insertion.
- Hold the jaw with an open-ended wrench when fastening an attachment; do not react the tightening torque through the gripper body. Use the specified screw length and torque to avoid internal damage.
- Use a flow-control valve to limit opening and closing speed. Commission at reduced pressure and low speed, and verify there is no collision before normal operation.
- Keep people and loose objects outside the moving envelope. Release the workpiece safely and exhaust the compressed air before removing the gripper.
Install finger attachments with the piston rods retracted to avoid scratching the rods and damaging their seals. The 32 mm bore has no axial through-hole mounting method in this catalog.

-
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. Select lead length to suit the installation independently of the combined jaw travel.
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 HFT gripper remains limited to +70°C. Ordinary, high-temperature and A05 sensors are IP64; W/A06 are IP68. These ratings do not extend to the gripper, 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 the matching sensor groove on the HFT body, using its included magnet; no separate sensor mounting bracket is required. 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 gripper 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 and electrical direction control
The two NPT gripper-side options require exact 1/4 inch OD soft nylon or PU tube. Do not substitute approximate metric tube diameters or PT/G threads. An inch-tube full order code and a complete valve-side connector or transition set are not specified here. Select compatible tubing and verify every connection from both gripper work ports to the control valve before assembly.

Optional 12 V DC direction control; 050/200 = 0.5/2 m leads; select for the installed supply and control system
The NPT A-type restricts gripper-to-tube exhaust and permits free charging; fitting/controller limits are 0–1 MPa and −20 to +70°C. Apply the specified tapered-thread seal and full tube insertion. Maximum controller-cap rotation torque is 0.08 N·m, not thread-tightening torque.
The listed complete M5-port valve codes are independent directional-control options. Their M5 ports do not directly mate with the NPT gripper ports or establish an inch-tube work line. Keep the two work paths separate and verify the actual tube and valve-side connections. These options are separately ordered, not a supplied or HFT-validated complete kit; valve flow, opening/closing time and gripping performance require selection for the actual load.
The listed 5V100 valves are 5/2 directional valves with M5×0.8 supply P, work A/B and exhaust R/S ports. Keep the two work lines separate and connect them to the gripper's opening and closing ports as required. The 5V110 version is single-solenoid spring return; 5V120 is double-solenoid with memory. Select the required switching and loss-of-power behavior; valve memory is not mechanical load retention.
Select one complete valve code for the installed supply. The final 050/200 means a 0.5/2 m terminal cable, not a DIN plug. AC tolerance is +15%/−10% at 2.0 VA; DC is ±10% at 1.6 W. Connect the selected voltage and control signals according to the valve wiring requirements.
The selected 5V100 valve is rated 0.15–0.8 MPa and −20 to +70°C. The common operating range of this selected HFT branch is 0.15–0.7 MPa and −20 to +70°C, subject to temperature derating and any lower installed-component limit.
