Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 450mm stroke and a built-in 4M210-08 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 SAIF32X450S-08A
The AirTAC SAIF32X450S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a 0.89 Cv flow rate. The cylinder body accepts PT 1/4 ports, while the valve manifold connects via O8xO5 PU tubing. Because the cylinder body rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
Generating 402N push force at 0.5 MPa, this 32mm bore unit includes a magnet (-S) for CMSE reed and DMSE electronic sensors. The factory setting retracts the rod when the coil is energised, which you can reconfigure to extend-when-energised by repositioning the valve. It switches itself from one coil signal, eliminating remote valves and reducing panel space for decentralized machine stations.

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 SAIF32X450S-08A Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on large machines, driving the 402N push action directly at the station via an AC220V signal.
Space-Constrained Automation
The integrated 4M210-08 valve manifold saves critical panel space and reduces tubing complexity in tight machine layouts.
Sensor-Equipped Positioning
The -S magnet pairs with CMSE reed and DMSE electronic switches to confirm the 450mm stroke endpoints for precise control.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08A the Right Choice?
Choose this 32mm bore if you need 402N push force at 0.5 MPa; stepping up to a 40mm bore yields 628N, while dropping to a smaller profile sacrifices too much thrust. The 450mm stroke demands a side-load guide to prevent rod binding. The integrated AC220V terminal coil activates in under 0.05s with IP65 protection, making it ideal for space-tight machines where running separate valve tubing is costly. Remember the 5/2 valve routes air and is not a lock; for load-holding, use a SAIL lock cylinder. To match this unit for replacement, verify the 32mm bore, 450mm stroke, 1/4" valve port, AC220V voltage, PT thread, terminal entry, 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 SAIF32X450S-08A FAQ
At 0.5 MPa, this 32mm bore cylinder generates 402N of push force and 345N of pull force. The built-in 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
No, the SAIF32X450S-08A switches itself using the built-in 4M210-08 valve driven by an AC220V terminal coil. By factory default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
