The AirTAC AirTAC SDA12X30SN Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 30mm 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 SDA12X30SN is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial mounting depth, while the 12mm bore generates 56.5 N of push force at 0.5 MPa. The hard-anodized inner wall and two-way piston seal ensure reliable service within the 0.15-1.0 MPa operating range.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-stops rely on a fixed NBR bumper that decelerates the stroke without adding length, rather than an adjustable air cushion. The 6mm piston rod features a female M3x0.5 thread, providing a compact coupling point for low-mass actuators.

Drives small vacuum pickups in electronics assembly, using the 56.5 N extend force to lift delicate circuit boards without demanding excessive machine footprint.
Moves a precision valve for chemical dosing, where the 30mm stroke and compact depth fit neatly inside crowded analytical instruments.
Pushes lightweight plastic components out of a molding fixture, relying on the fixed NBR bumper to absorb the end impact at operating speeds up to 500 mm/s.
For this 12mm bore, the theoretical push is 56.5 N at 0.5 MPa, yielding a safe working load of roughly 34 N (about 60% capacity) and a vertical lift capability of approximately 2.9 kg with a 2:1 safety margin. If your application requires slightly more thrust, the next size up is the SDA16, which provides 100.5 N of push at 0.5 MPa. As the smallest available bore in the series, there is no smaller standard option.
When ordering, confirm the 12mm bore, 30mm stroke, M5x0.8 air port, and the built-in magnet for position sensing. Note that a plain SDA cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the piston near stroke end and does not function as a locking brake. For suspended loads, specify an external rod lock or pilot-operated check valve.
Quick checklist
This 12mm bore double-acting cylinder provides 56.5 N push and 42.4 N pull at 0.5 MPa, and 79.2 N push and 59.4 N pull at 0.7 MPa. The theoretical maximum push is 12 kgf at the maximum operating pressure of 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, the cylinder cannot hold a load if air is lost; the piston will drift, requiring an external rod lock or check valve for secure positioning.
