Airtac SAIF Series Standard Cylinder with Valve SAIF40X400S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X400S-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm 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 SAIF Series Standard Cylinder with Valve SAIF40X400S-06A
The AirTAC SAIF40X400S-06A is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a 0.78 Cv flow rate. Driven by an AC220V terminal coil consuming 3.5 VA, it integrates switching directly on the actuator. The assembly operates within a 0.15-0.8 MPa pressure range, as the integrated valve limits the 1.0 MPa cylinder baseline. At 0.5 MPa it generates 628N of push force. This unit includes a magnet for CMSE reed and DMSE solid-state sensors.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The manifold links the valve to the cylinder via O8xO5 PU tubing, meaning the 1/8" valve port differs from the cylinder's 1/4" port. This decentralized design eliminates remote plumbing, saving panel space across large machines.

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAIF40X400S-06A Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on long production lines, driving localized 628N motions directly from a single AC220V signal.
Space-Constrained Automation
Ideal for tight retrofits where running new valve tubing is costly, using the built-in 4M210 valve to switch the 400mm stroke actuator on-site.
Material Handling Gates
Provides reliable 0.15-0.8 MPa operation for diverting mechanisms, with a 1/8" valve port and O8xO5 PU manifold keeping the envelope compact.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X400S-06A the Right Choice?
Choose this 40mm bore when an application requires 628N push force at 0.5 MPa; stepping down to a 32mm bore yields 402N, while a 50mm bore offers 982N. The self-contained SAIF series outperforms a separate cylinder and remote valve setup by cutting tubing complexity and wiring, making it perfect for decentralized stations. This specific configuration uses an AC220V terminal connection and PT threaded ports. For stroke lengths of 400mm, ensure external guide rails are used to manage side loads and prevent rod binding. To reorder, match the 40mm bore, 400mm stroke, 06 valve port, AC220V terminal coil, PT thread, and -S magnet. Note that the 5/2 valve routes air but does not lock the load; for true position holding, consider the SAIL lock series.
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 SAIF40X400S-06A FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
The factory setting retracts the rod when the AC220V coil is energised. By repositioning the valve, you can reconfigure it to extend-when-energised. The 5/2 valve holds its position via internal pilot pressure, not a spring, but it does not lock the load.
