The AirTAC SDA Ultra Thin Cylinder SDA12X50 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 SDA12X50 is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. It delivers 56.5 N of push force and 42.4 N of pull force at 0.5 MPa. A short riveted assembly merges the barrel, rear cover, piston, and rod, drastically reducing overall length compared to round-body alternatives. This specific configuration lacks a piston magnet, so it cannot support magnetic sensing.
Built with a hard-anodized bore and a two-way piston seal, this unit operates at speeds from 30 to 500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. With a 12 mm bore and 50 mm stroke, the M5x0.8 port provides pneumatic supply to the chamber.

Pushes separated circuit boards off a routing fixture with 56.5 N of force, fitting neatly into dense electronics assembly machinery.
Acts as a 50 mm stroke actuator to press a pipette head into microplates, benefiting from the short axial length to conserve lab bench space.
Diverts miniature plastic or metal fasteners on a conveyor line, using the fixed NBR bumper to quietly absorb the 30-500 mm/s travel stops.
When sizing this 12 mm bore actuator, note that it reaches its maximum standard stroke of 50 mm at this exact length. If your application requires less force, you must step down to a smaller bore, but the SDA12 is the smallest available option in this series. Stepping up to the SDA16 increases your 0.5 MPa push force to 100.5 N. This SKU features a female M3x0.5 rod-end thread and no magnet; selecting the -S option adds a magnet for reed or electronic switches, while the -B option changes the rod end to a male M5x0.8 thread. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered; holding a load vertically requires an external rod lock or a pilot-operated check valve.
Quick checklist
This 12 mm bore double-acting cylinder provides 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 force is 79.2 N and the pull force is 59.4 N. The theoretical maximum push force is 12 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, this specific SKU lacks the -S code, meaning it has no piston magnet and cannot accept reed or electronic switches. Regarding end-of-stroke damping, it uses a fixed NBR bumper to decelerate the piston, not an adjustable air cushion. For high-energy cycles, you should slow the approach speed or add an external shock absorber.
