Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-06B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 250mm 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 SAIF Series Standard Cylinder with Valve SAIF32X250S-06B
The AirTAC SAIF32X250S-06B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve. Delivering a Cv of 0.78 with a 14.0 mm2 orifice, this integrated assembly operates on a DC24V terminal coil drawing 3.0 W. It includes an -S magnet for precise position detection using AirTAC CMSE reed or DMSE electronic sensors. While the bare cylinder rates to 1.0 MPa, the practical working range for this valved unit is 0.15-0.8 MPa.
Driven by a single coil signal, it eliminates the need for a remote valve bank, saving panel space and tubing across decentralized stations. The manifold bridges the 1/8 cylinder port and the 1/8 valve port using PU tubing (O8 x O5). By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your logic requires it.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø32mm)

|---|---|---|
| 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.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-06B Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing by driving the 32mm bore directly from the built-in 4M210 valve, saving panel space across large manufacturing lines.
Compact PCB Handling
Fits tight machine envelopes with its ISO 15552 profile, delivering 402N push force at 0.5 MPa while switching itself via a single DC24V signal.
Retrofit Automation
Ideal for upgrading older pneumatic lines where adding external valve islands is impractical, providing 5/2 control with a 0.05s response time.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-06B the Right Choice?
Choose this 32mm bore when you need compact thrust (402N push at 0.5 MPa); step up to the 40mm bore if your load requires 628N. The self-valved SAIF design excels in space-tight machines where running separate valve tubing is costly, though note the 5/2 valve routes air and does not lock the load—use SAIL for load-holding. At 250mm stroke, ensure adequate guide support to prevent rod side-loading. Replacement requires matching the 32mm bore, 250mm stroke, 06 valve port, DC24V voltage, terminal entry, PT thread, and -S magnet.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF32X250S-06B FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, the 5/2 valve routes air but does not lock the load. By default, the rod retracts when the DC24V coil is energised, but it can be repositioned to extend-when-energised. For true load holding, consider the SAIL lock cylinder.
