Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 350mm 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 SAIF50X350S-06A
The AirTAC SAIF50X350S-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal entry coil consuming 3.5 VA, it delivers a 0.5 MPa push force of 982 N. The integrated valve has a 14.0 mm2 orifice (Cv 0.78) and switches at up to 5 cycles per second. Because the valve mounts directly via a manifold block and O8 x O5 PU tubing, you save panel space and eliminate remote plumbing.
The assembled unit operates from 0.15-0.8 MPa, as the valve pilot limits the 1.0 MPa cylinder rating. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This 350 mm stroke variant includes a magnet for CMSE reed and DMSE electronic sensors, and uses a PT1/8 valve port alongside the PT1/4 cylinder port.

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 SAIF50X350S-06A Is Used
Decentralized Stations
Ideal for large machines where running individual valve tubing is costly, as the integrated 4M210 valve switches the cylinder directly from the AC220V signal.
Extended Stroke Handling
Suited for 350 mm reach operations requiring 982 N push force at 0.5 MPa, provided external guides manage the side-load on the extended rod.
Sensor-Ready Automation
The -S magnet enables precise position detection using CMSE reed or DMSE electronic switches in tight retrofits where panel space is limited.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X350S-06A the Right Choice?
Choose this self-valved SAIF50X350S-06A when decentralizing actuators across a large machine, as one coil signal drives the cylinder without a separate remote valve. If your application requires less force, stepping down to a bore 40 unit yields 628 N push at 0.5 MPa; stepping up to a bore 63 cylinder provides 1559 N. At 350 mm stroke, guide the load to prevent excessive side-loading on the rod seals. Remember the 5/2 valve routes air and is not a lock; for static load holding, select an SAIL lock cylinder. Replacement requires matching the 50 mm bore, 350 mm stroke, 06 valve port, AC220V terminal coil, 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 SAIF50X350S-06A FAQ
At 0.5 MPa, the 50 mm bore provides 982 N push and 825 N pull force. The built-in 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78).
No, the integrated 4M210 valve switches the cylinder directly from the AC220V terminal coil signal. The factory setting retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
