SMC RMHF2 Air Gripper Unit for Collaborative Robots — Long Stroke Type
SMC
The SMC RMHF2 is a pneumatic air gripper unit designed specifically for collaborative robots (cobots). Part of the RMH series, it features a 64 mm long stroke, 90 N gripping force, and a height approximately 35% lower than the standard RMHZ2 type. It connects to a cobot arm via a single air supply tube and a single electrical cable (24 VDC), with a built-in solenoid valve, integrated speed adjustment mechanism, and auto switch. Compatible with 13 cobot platforms including Universal Robots, FANUC, YASKAWA, ABB, KUKA, Mitsubishi Electric, DOOSAN Robotics, OMRON/Techman, SIASUN, JAKA, AUBO, HAN'S Robot, and DENSO WAVE. A built-in tool changer enables fast end-of-arm tool swaps in clamp, one-push, or auto variants.

Switch / Sensor Selection (Position 2)
| Code | Description | Use When |
|---|---|---|
| N | Auto Switch — NPN output (D-M9N) Switch (1) detects finger closing; Switch (2) detects finger opening |
Controller uses NPN (sinking) logic |
| P | Auto Switch — PNP output (D-M9P) | Controller uses PNP (sourcing) logic |
| A | Actuator Position Sensor — D-MP050 (0–10 V analog) Enables workpiece length measurement. UR, FANUC, DENSO WAVE only. |
Precise stroke position feedback required |
Valve Option (Position 3)
| Code | Description | Use When |
|---|---|---|
| (blank) | Basic Type — both solenoids N.C. Max frequency: 60 CPM |
Standard pick-and-place; state controlled by active air |
| O | Normally Open — SOL1 is N.O., SOL2 is N.C. Requires piping plate RMH-A00-06. Max frequency: 50 CPM. |
Gripper must default OPEN on power loss |
| C | Normally Closed — SOL1 is N.C., SOL2 is N.O. Requires piping plate RMH-A00-06. Max frequency: 50 CPM. |
Gripper must retain grip on power loss |
| Drop prevention warning: When using N.O. or N.C. valve options, a customer-supplied check valve must be installed on the air supply to prevent exhausting when power is cut. Gripping force gradually decreases after power loss — move workpiece to a safe position immediately. Do not continue transferring workpieces without air supply. |

Solenoid Valve ON/OFF State & Gripper Action
Solenoid valve (1) controls finger opening; solenoid valve (2) controls finger closing. Two exhaust throttle valves (with silencer) provide independent speed adjustment for each direction.
| Solenoid (1) | Solenoid (2) | Basic Type | Normally Open | Normally Closed |
|---|---|---|---|---|
| OFF | OFF | No pressure — fingers moveable by hand, zero grip force | Finger opening | Finger closing |
| ON | OFF | Finger opening | No pressure applied | Pressure to both sides |
| OFF | ON | Finger closing | Pressure to both sides | No pressure applied |
| ON | ON | Pressure both sides — small opening force due to internal construction | Finger closing | Finger opening |
Installation

|---|---|
| Connector to main plate (M2.5×20) | 0.36±0.03 N·m |
| Main plate to robot flange (M6×18) | 5.2±0.5 N·m |
| Extension flange bolt (M6×15) — OMRON/Techman with camera | 5.2±0.5 N·m |
| Finger attachment bolt (M4×0.7) | 1.5±0.15 N·m |
| Protective cover bolt (M3×0.5) | 0.63±0.06 N·m |
| Body tapped holes — lateral/bottom (M5×0.8) | 2.7 to 3.3 N·m, max screw-in depth 5.5 mm |
| Auto switch screw | 0.05 to 0.15 N·m |
| Gripper ASSY screws (M4×8) | 1.5±0.15 N·m |
Main Plate Installation Steps
| Step | Action |
|---|---|
| 1 | Insert positioning pins (2×4) into the main plate. |
| 2 | Attach the connector to the main plate using M2.5×20 screw. Torque: 0.36±0.03 N·m. |
| 3 | Insert positioning pin (6×10) into the pin hole on the robot tool flange. |
| 4 | Attach the main plate while aligning the positioning pins. |
| 5 | Secure with M6×18 bolt. Torque: 5.2±0.5 N·m. |
| OMRON/Techman with camera only: Install extension flange RMH-A00-20 between robot and main plate. Flange bolt (M6×15): 5.2±0.5 N·m. Then attach main plate with M6×18 at 5.2±0.5 N·m. |
Finger Speed Adjustment
| Step | Action |
|---|---|
| 1 | Locate the two metering valves on the gripper body — one controls opening speed, one controls closing speed. |
| 2 | Use a flat blade screwdriver, blade width 0.7 mm, to adjust the opening of each exhaust restrictor. |
| 3 | Set both restrictors to approximately the same opening level. Large differences between the two will cause unstable operation. |
Auto Type Tool Changer — Connection & Release Procedure
| To Connect (from released state) | |
|---|---|
| 1 | Supply air to A port (this releases the lock mechanism). |
| 2 | Move the main plate to above the tool plate. |
| 3 | Lower the main plate to within 1 mm of the tool plate. Align within: ±2 mm lateral, 1.5° inclination, ±3° rotation. |
| 4 | Supply air to B port. Steel ball locks — connection complete. |
| To Release (from connected state) | |
| 1 | Supply air to A port. |
| 2 | Pull the main plate upward by 10 mm or more. |
| ⚠ Critical — read before operating: Never apply air to the B port before the A port when connecting from the released state. Doing so causes the protruded steel ball to collide with the tool plate and risks product breakage. The changer has a mechanical retention mechanism that holds the connection when air is cut — this is for emergency drop prevention only. Do not transfer workpieces without air supply. |
Air Supply Requirements
| Requirement | Detail |
|---|---|
| Filtration | Install air filter upstream of valve. Filtration degree: 5 µm or finer. |
| Moisture | Install air dryer or water separator upstream. Drain condensate regularly. Auto drain recommended if bowl is difficult to check. |
| Air Quality | Clean, dry compressed air only. Do not use air containing chemicals, synthetic oils (including organic solvents), salt, or corrosive gases. |
| Freeze Risk | If fluid temperature falls below 5°C, moisture in the circuit may freeze. Take appropriate anti-freeze measures. |
| Lubrication | Non-lube type — no lubrication required. If lubrication is already used in the system, use turbine oil Class 1 (no additive, ISO VG32). Once applied, lubrication must be continued — stopping causes malfunction. |
| Dry Air | Ultra-dry air may degrade lubrication properties inside the unit. Consult SMC before using dry air. |
| Before Piping | Flush all lines with air before connecting to remove cutting chips, oil residue, and dust. |
Operating Environment
| Prohibited Environments | Corrosive gases, chemicals, sea water, water spray, steam, direct sunlight, vibration, impact, radiant heat |
| Corrosion Note | Finger guide rail uses martensitic stainless steel — corrosion resistance is inferior to austenitic stainless. Rust may form where condensation collects. Use protective cover (option D) in humid or wet environments. |
| Inertial Force Caution | Finite orbit type guide is used in the finger part. When the robot generates inertial forces through movement or rotation, operate the finger to full stroke to reset the guide. Failure to do so causes accuracy degradation over time. |
| Intended Use | Workpiece transportation only. Do not use for positioning or clamping applications without consulting SMC. |

Application Examples
| Industry | Application | Why the RMHF2 |
|---|---|---|
| Automotive | Small Part Assembly & Kitting | 64 mm stroke handles variation in part geometry across a model family without reconfiguring the gripper between runs. |
| Electronics Mfg. | PCB & Component Handling | D-MP analog position sensor enables workpiece length discrimination directly from the gripper stroke — no separate vision system required for simple size checks. |
| Food & Beverage | Carton & Pouch Pick-and-Place | Normally-closed valve option (C) retains grip if air pressure drops, preventing product drops during e-stops. |
| Machine Tending | CNC & Lathe Loading | Protective cover option (D) shields internal components from metal chips and coolant mist. |
| Logistics | Bin Picking & Sortation | Wide stroke range reduces need for custom fingers across part families in high-mix environments. |
| Medical Devices | Assembly & Inspection Transfer | Single-wire electrical connection and unrestricted mounting orientation simplify integration into compact, safety-rated cobot cells. |
Frequently Asked Questions
| What is the difference between the RMHF2 and the RMHZ2? | |
| The RMHF2 is the long stroke variant: 64 mm stroke, 90 N force, 945 g (clamp type), 35% lower height than the RMHZ2. The RMHZ2 is the standard type: 14 mm stroke, 54.2/72.2 N force, 638 g. Choose the RMHF2 when workpiece size variation requires a wider stroke range. Choose the RMHZ2 when mass and height are priorities. | |
| Does the RMHF2 work with Universal Robots UR10e? | |
| Yes. The UR10e is supported under codes 011A (analog/D-MP sensor) and 011P (PNP switch), covering all e-Series: UR3e, UR5e, UR10e, UR16e. All three tool changer types supported. Connector cable: RMH-A00-11-A. | |
| Does the RMHF2 work with FANUC CRX cobots? | |
| Yes. FANUC CRX is supported under codes 051A (analog) and 051P (PNP), covering CRX-5iA, CRX-10iA, CRX-10iA(L), CRX-20iA, and CRX-30iA. All three tool changer types supported. Connector cable: RMH-A00-11-A. | |
| What is the operating pressure range? | |
| 0.1 to 0.7 MPa for gripper operation. Auto type tool changer requires 0.2 to 0.7 MPa. Gripping force spec (90 N) is measured at 0.5 MPa with gripping point L = 20 mm. | |
| What are the TCP coordinates for programming? | |
| TCP: X = 0, Y = 0, Z = 89.3 mm (measured from robot flange to finger tip with no attachment). Update Z when finger attachments are installed. Center of gravity: X = −0.85 mm, Y = −0.31 mm, Z = 53.33 mm. | |
| How do I adjust the finger opening and closing speed? | |
| Use a flat blade screwdriver (blade width 0.7 mm) on the two metering valves on the gripper body. One controls opening speed, one controls closing speed. Keep both at approximately the same opening — large differences cause unstable operation. | |
| Which robots support the D-MP actuator position sensor (switch code A)? | |
| Universal Robots (011A), FANUC CRX (051A), and DENSO WAVE COBOTTA PRO (141A) only. Not available for KUKA, YASKAWA, DOOSAN, SIASUN, JAKA, AUBO, HAN'S Robot, ABB, Mitsubishi Electric, or OMRON/Techman. | |
| What does the D-MP sensor output and how is it calibrated? | |
| 0 V = fully closed (0 mm); 10 V = fully open (64 mm). Resolution 0.05 mm. Ships with factory defaults set — do not change unless necessary. For exact calibration use a 64 mm block gauge (the actual full-open stroke is slightly larger than 64 mm). | |
| When should I select the normally closed valve option (code C)? | |
| Select code C when the gripper must retain grip on power loss. You must also install a customer-supplied check valve on the air supply. Gripping force gradually decreases after power loss — move the workpiece to safety immediately. N.C. option requires piping plate RMH-A00-06 and reduces max frequency to 50 CPM. | |
| Does the RMHF2 work with KUKA cobots? | |
| Yes, with constraints. Code 061P supports the KUKA LBR-iiwa, but only with the I/O Pneumatic media flange. Max temperature 40°C. Power supply range wider: 24 VDC −15%/+20%. Auto type tool changer not supported. D-MP sensor not available. Cable: RMH-A00-11-B. | |
| Is plug-in software available? | |
| Yes. URCap for Universal Robots, Plug and Play Kit for YASKAWA, TMComponent for OMRON/Techman, CRX Plug-in for FANUC, and Library for DENSO WAVE. Allows gripper programming from the teach pendant without custom code. | |
| Can I mount multiple grippers on one robot? | |
| Yes. SMC RMMA Series Multi Hand Adapter supports up to 3 grippers simultaneously. Mounting angles: 90°, 120°, or 180° (two 90° adapters). ISO 9409-1-50-4-M6 compliant. | |
| What is the warranty period? | |
| 1 year in service or 1.5 years from delivery, whichever comes first. Warranty applies to the product independently and does not cover consequential damage to other equipment. |
