Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 400mm stroke and a built-in 4M210-06 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-06B
The SAUF32X400S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, saving tubing and a manifold slot in decentralized setups. The 32mm bore delivers 402N push at 0.5MPa. The cylinder body rates to 1.0MPa, but size force within the valve's 0.15-0.8MPa window.
This model includes a piston magnet for CMSG/DMSG/EMSG switches. The integrated valve has a 1/8" port, Cv 0.78 flow, and runs up to 5 cycles/sec. It uses a DC24V coil with terminal entry. The bore's air port is 1/8". For sizing, the safe working load is roughly 241N, and vertical lift is about 20kg with a 2:1 margin.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-06B Is Used
Decentralized Clamping
Ideal for clamping stations where running a separate remote valve is impractical, letting one DC24V signal control the clamp directly.
Package Diverting
Perfect for diverting arms on conveyors, saving manifold slots by switching the 400mm stroke actuator locally at the action point.
Compact Sorting
Fits space-constrained sorting machines where the profile cylinder and built-in valve minimize plumbing across long distances.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-06B the Right Choice?
Compare with the 40mm bore if you need more push (628N at 0.5MPa) or stick with 32mm for lighter 402N loads. Confirm the DC24V terminal entry and PT threads fit your control panel. The rod retracts when the coil energises; reposition the valve to switch to extend-when-energised. Keep pressure between 0.15-0.8MPa. The valve routes air but does not lock the load—add an external rod lock or pilot-operated check valve for holding. At 400mm stroke, use external guides to prevent rod bending and side loads.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-06B FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate in the 0.15-0.8MPa valve window.
No. The 5/2 valve routes air but is not a lock, so the piston drifts on air loss. For load holding, install an external rod lock or pilot-operated check valve. Also, the rod retracts by default when energised, but you can reposition the valve to extend instead.
