Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06E 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-06E
The AirTAC SAIF40X50S-06E is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve. Delivering a Cv of 0.78 and a 14.0 mm2 effective orifice, this integrated unit switches itself from a single AC24V terminal connection, eliminating remote plumbing. It includes a magnet for position sensing with CMSE reed and DMSE electronic switches. The standard carbon steel rod and PT1/8 cylinder port complete the robust assembly.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this valved unit is 0.15-0.8 MPa. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold links the valve to the cylinder via an O8 x O5 PU tube, and the unit delivers 628N of push force at 0.5 MPa.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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-06E Is Used
Decentralized Assembly Stations
Ideal for large machines with multiple stations, using the built-in valve to cut down on central panel space and long tubing runs.
Compact Electronics Handling
The 40mm bore with integrated switching provides responsive 628N actuation in tight machine layouts where external valves won't fit.
Retrofit Automation Lines
Perfect for upgrading existing lines where adding a remote valve manifold is too costly, simply wire the AC24V terminal and go.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X50S-06E the Right Choice?
Choose this self-valved SAIF40X50S-06E when you need decentralized control across a large machine without running separate valve tubing. It provides 628N push and 528N pull at 0.5 MPa; if your application requires less force, step down to the 32mm bore (402N push), or step up to the 50mm bore (982N push) for heavier loads. The AC24V terminal coil draws 3.5 VA and responds in 0.05s. Note that the 5/2 valve routes air but does not lock the load—use a SAIL lock cylinder for position holding. Replacement matches require a 40mm bore, 50mm stroke, 06 valve port, AC24V voltage, terminal entry, PT thread, and the -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 SAIF40X50S-06E FAQ
The 40mm bore generates 628N push and 528N pull at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78.
It uses a 5/2 solenoid valve that holds position via internal pilot pressure. The factory setting retracts the rod when the AC24V coil energizes, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
