Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06C
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06C is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 50mm 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 SAIF40X50S-06C
The AirTAC SAIF40X50S-06C is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. Driven by an AC110V terminal coil drawing 3.5 VA, it achieves a 0.05 s response time. The integrated valve provides an effective area of 14.0 mm2 (Cv 0.78) and routes air through an O8 x O5 PU tube to the 1/8 cylinder port. Because the valve limits the system, the practical operating pressure is 0.15-0.8 MPa, despite the cylinder body rating of 1.0 MPa.
This self-contained unit generates 628 N of push force and 528 N of pull force at 0.5 MPa. It includes a magnet for CMSE reed and DMSE electronic 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. This decentralized design eliminates remote valves, reducing panel space and plumbing across large machines.

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 (Ø40mm)

| 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 SAIF40X50S-06C Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve bank, allowing individual AC110V control of clamping arms directly at the workstation.
Compact Sorting Diverters
Ideal for space-tight conveyor lines where the integrated 4M210 valve minimizes tubing and accelerates the 0.05 s sorting response.
Machine Retrofitting
Simplifies upgrades on large machines by routing a single electrical signal to the terminal, avoiding complex pneumatic plumbing runs.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06C the Right Choice?
Choose this 40 mm bore if you need 628 N push force at 0.5 MPa; step down to a 32 mm bore for 402 N, or up to a 50 mm bore for 982 N. The SAIF40X50S-06C excels in decentralized stations where running separate valve tubing is costly, as one AC110V terminal connection drives the entire actuator. The 5/2 valve holds its position via pilot pressure, not a spring, but it will not hold a load without live air pressure—select a SAIL lock cylinder if mechanical holding is required. With a 50 mm stroke, side-load risks are minimal, but ensure proper guide alignment for optimal 30-800 mm/s speed operation.
When ordering a replacement, verify the 40 mm bore, 50 mm stroke, 1/8 cylinder port, and 06 (1/8) valve port. Confirm the AC110V voltage, PT tapered threads, terminal electrical entry, and the -S magnet for CMSE/DMSE sensors.
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 SAIF40X50S-06C FAQ
At 0.5 MPa, it provides 628 N push and 528 N pull force. The built-in 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, the integrated 5/2 solenoid valve switches the cylinder directly from the AC110V terminal signal. Factory-set to retract when energised, the valve can be repositioned to extend-when-energised without extra parts.
