The AirTAC AirTAC SDA12X5B Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 5mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA12X5B is a double-acting, single-rod compact cylinder engineered for extremely tight axial spaces. It generates a 56.5 N push force at 0.5 MPa, yielding a safe working load of roughly 34 N or a 2.9 kg vertical lift with a 2:1 margin. The riveted body design drastically reduces overall mounting length compared to round-body units.
This specific SKU features a male M5x0.8 piston rod thread for direct load coupling. The bore is hard-anodized and uses a two-way piston seal operating at speeds from 30 to 500 mm/s. Because it lacks the -S option, this unit has no piston magnet and cannot accept AirTAC reed or electronic switches.

Drives the short 5 mm jaw movement inside small pneumatic grippers used for handling delicate electronic components during PCB assembly.
Toggles precision dispensing nozzles in automated chemical analyzers where the 56.5 N force easily overcomes internal fluid pressure.
Provides a rapid 5 mm kick to eject small molded plastic parts from tight tooling cavities without extending the machine footprint.
For sizing context, stepping up to the SDA16 increases the 0.5 MPa push force to 100.5 N. Since this is the smallest bore in the series, there is no smaller adjacent option. When ordering this model, confirm the 12 mm bore, 5 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and that no sensing magnet is required.
Keep in mind that a standard compact actuator does not hold its position if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke end and acts neither as an adjustable air cushion nor a locking brake. If your application must hold a load without live pressure, you need an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 56.5 N and the pull force is 42.4 N. At 0.7 MPa, the push force is 79.2 N. The theoretical maximum push force is 12 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify an SDA12X5SB to gain sensing capabilities via the body grooves.
