The AirTAC AirTAC SDA12X50SN Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 50mm 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 SDA12X50SN is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly significantly reduces axial mounting depth compared to round-body alternatives, while the hard-anodized 12 mm bore yields a push force of 56.5 N at 0.5 MPa. Equipped with a built-in piston magnet, the body grooves readily accept AirTAC reed or electronic switches for precise position detection.
This 50 mm stroke unit relies on a fixed NBR bumper at each end to decelerate the piston, meaning it is not an adjustable air cushion. Operating at speeds between 30 and 500 mm/s, it features a 6 mm rod and an M5x0.8 port. The compact body design is ideal for applications requiring minimal space without sacrificing reliable linear motion.

Handles delicate electronic part placement on printed circuit board assembly lines, utilizing the 56.5 N push force and short riveted body to fit within dense robotic picker arrays.
Actuates small test tube racks in automated medical analyzers, where the 50 mm stroke and integrated magnet provide reliable reed or electronic switch feedback for precise routing.
Folds lightweight cardboard flaps on pharmaceutical packaging machines, benefiting from the fixed NBR bumper to absorb the 30-500 mm/s travel impact without requiring external cushions.
When sizing this 12 mm bore actuator, stepping up to the SDA16 provides a higher push force of 100.5 N at 0.5 MPa, whereas the SDA12 offers 56.5 N for lighter duty. Based on the 0.5 MPa push rating, the safe working load is approximately 34 N (about 60 percent of capacity), which translates to a vertical lift capability of roughly 2.9 kg when applying a 2:1 safety margin. To confirm your ordering essentials for this model: specify the 12 mm bore, 50 mm stroke, M5x0.8 port, built-in magnet (S), and female rod-end thread. Note that a plain cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end rather than locking the load; an external rod lock or pilot-operated check valve is required to hold a position securely.
Quick checklist
This 12 mm bore double-acting 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 increases to 79.2 N. The theoretical maximum push is 12 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper at each end only decelerates the rod near the stroke limits and does not function as a locking brake. To maintain a vertical position without live pressure, you must install an external rod lock or a pilot-operated check valve.
