Airtac SAIF Series Standard Cylinder with Valve SAIF40X200S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X200S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 200mm stroke and a built-in 4M210-08 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 SAIF40X200S-08A
The AirTAC SAIF40X200S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific configuration delivers a 16.0 mm2 effective area (Cv 0.89) and operates via a PT1/4 valve port, while the cylinder body utilizes a PT1/4 port. Driven by an AC220V terminal connection coil drawing 3.5 VA with an IP65 rating, it provides 628N of push force at 0.5 MPa. Because the valve manifold limits pressure, the practical working range for this assembled unit is 0.15-0.8 MPa, despite the bare cylinder rating of 1.0 MPa.
Factory-set to retract the piston rod when the coil is energised, the valve can be physically repositioned to extend-when-energised if your sequence demands it. The manifold links the valve to the cylinder using O8 x O5 PU tubing, meaning the valve port and cylinder port serve distinct roles in the assembly. Equipped with a magnet for position sensing, this unit works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. By controlling itself from a single electrical signal, it eliminates remote plumbing and is ideal for decentralized machine stations.

|---|---|---|
| 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 SAIF40X200S-08A Is Used
Decentralized Assembly Stations
Eliminates the need for a central valve bank by processing the 5/2 switching directly on the cylinder, reducing pneumatic tubing runs across large automated assembly lines.
Space-Constrained Machinery
The integrated manifold block saves valuable panel and footprint space, requiring only a single AC220V electrical connection to drive the 200mm stroke.
Retrofit & Upgrade Projects
Ideal for upgrading existing lines where adding new air lines is prohibitive, leveraging the built-in 4M210 valve and CMSE/DMSE sensor track for drop-in automation.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X200S-08A the Right Choice?
Select this 40mm bore when a 32mm bore falls short on thrust (offering 402N push at 0.5 MPa) and a 50mm bore is excessive (delivering 982N at 0.5 MPa). The 200mm stroke suits medium-travel handling and clamping tasks. Because the stroke is below 300mm, standard mounting handles the kinetic energy without auxiliary side-load guides. Choose this self-valved SAIF configuration over a separate cylinder and remote valve when panel space is tight and running pneumatic tubing across a large machine is costly; a single AC220V wire reaches the station instead.
When ordering a replacement, verify the 40mm bore, 200mm stroke, 1/4" valve port, AC220V terminal entry, PT thread, and the -S magnet. Remember that the 5/2 valve routes air but does not lock the load mechanically—without live pressure the cylinder will not hold position. For true mechanical load-holding, specify an AirTAC SAIL pneumatic lock cylinder instead.
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 SAIF40X200S-08A FAQ
The 40mm bore generates 628N of push force and 528N of pull force at 0.5 MPa. The built-in 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) and can cycle up to 5 times per second without load.
Yes. The factory setting retracts the rod when the AC220V coil is energised, but you can reposition the 5/2 valve on the manifold to extend-when-energised. This self-contained switching eliminates the need for a separate remote valve.
