Airtac SAIF Series Standard Cylinder with Valve SAIF50X150S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X150S-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 150mm 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 SAIF50X150S-06A
The AirTAC SAIF50X150S-06A is a double-acting ISO 15552 profile cylinder that integrates a 4M210-06 5/2 solenoid valve directly onto the body. The built-in valve provides an effective flow of 14.0 mm2 (Cv 0.78) and operates at 5 cycles per second. Driven by an AC220V terminal entry coil consuming 3.5 VA, it activates in under 0.05 seconds. While the cylinder itself is rated for 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa.
By controlling itself from a single electrical signal, this unit eliminates the need for remote plumbing and saves panel space, making it ideal for decentralized stations. The manifold connects to the cylinder via PU tubing (O8 x O5). From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This -S variant includes a magnet for CMSE reed and DMSE electronic sensors.

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 (Ø50mm)

| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X150S-06A Is Used
Decentralized Machine Stations
Eliminates long tubing runs from a central panel by switching the cylinder directly at the station via the AC220V terminal signal.
Compact Assembly Automation
Saves valuable envelope space on tight machinery by mounting the 4M210 valve and manifold straight onto the ISO 15552 profile body.
Retrofit and Upgrades
Simplifies electrical wiring upgrades on older equipment where running new pneumatic tubing is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X150S-06A the Right Choice?
Choose this 50 mm bore when you need the 982 N push force at 0.5 MPa; stepping down to a 40 mm bore drops the push force to 628 N, while an 80 mm bore raises it to 2513 N. The self-valved SAIF design is superior to a separate cylinder and remote valve when you want to minimize tubing across a large machine. This specific SKU uses an AC220V terminal coil and a PT1/8 valve port. Remember that the built-in 5/2 valve routes air but does not lock the load; for position holding, consider an SAIL lock cylinder. To replace this unit, match the 50 mm bore, 150 mm stroke, 4M210-06 valve, AC220V voltage, terminal entry, PT threads, 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 SAIF50X150S-06A FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78).
The 5/2 valve is internally piloted and holds its last position by pilot pressure, not by a spring, so it is not a load-locking device. By factory default, the rod retracts when the AC220V coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
