The AirTAC SDA12X5H 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 SDA12X5H is a double-acting single-rod compact cylinder engineered for extremely tight axial spaces. Its riveted body assembly minimizes overall length compared to round-body units, yielding a 56.5 N push force at 0.5 MPa. This specific SKU features a fluororubber (FKM) seal for enhanced thermal and oil resistance, operating reliably across a 30-500 mm/s speed range.
Equipped with a 6 mm piston rod and an M5x0.8 port, the unit relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this configuration lacks the -S piston magnet, it cannot support magnetic sensing. Theoretical maximum output is 12 kgf at 1.0 MPa.

Drives 5 mm ejection strokes in compact PCB assembly tooling, utilizing the 56.5 N push force to clear delicate components without consuming valuable Z-axis height.
Toggles small-bore fluid valves in automated chemical dispensing, where the FKM seal resists oil-based reagents and the short riveted body fits inside crowded fume hoods.
If your application requires slightly more force, the next size up is the SDA16, which provides 100.5 N push at 0.5 MPa. As the smallest available bore, stepping down is not an option.
When ordering, confirm the 12 mm bore, 5 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the FKM seal option. Note that a plain cylinder does not hold its load if air pressure is lost or the valve is centred; the piston will drift. To maintain position, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 12 mm bore cylinder generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, the push is 79.2 N and the pull is 59.4 N. The theoretical maximum push is 12 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include the -S piston magnet, so it cannot accept AirTAC reed or electronic switches. Detection would require the -S variant. Additionally, end-stop deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
