The AirTAC SDA12X45SN Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 45mm 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 SDA12X45SN is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly yields a very short axial length, conserving mounting depth where conventional round-body units cannot fit. Operating at 0.15-1.0 MPa, it generates 56.5 N of push force and 42.4 N of pull force at 0.5 MPa, making it suitable for light-duty positioning.
This 12mm bore variant incorporates a built-in piston magnet for direct compatibility with AirTAC reed or electronic switches via the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion. The 6mm piston rod features a female M3x0.5 thread end, and air connections use an M5x0.8 port.

Actuates fine pick-and-place heads in electronics assembly, utilizing the 45mm stroke and 56.5 N force to position small parts without excessive axial bulk.
Indexes sample trays in compact diagnostic machinery where the short riveted body conserves valuable equipment interior space.
Tucks lightweight cardboard flaps on automated packaging lines, relying on the fixed NBR bumper to absorb the end-stop impact within the 30-500 mm/s speed range.
If your application requires less force, there is no smaller standard SDA bore. Stepping up to the SDA16 increases the push output to 100.5 N at 0.5 MPa. A plain double-acting cylinder will not hold a load if air pressure drops or the valve centers; the piston drifts until the bumper contacts the end cap. For suspended loads, specify an external rod lock or a pilot-operated check valve. When ordering, confirm the 12mm bore, 45mm stroke, M5x0.8 port, female rod thread, and the -S magnet option.
Quick checklist
This 12mm bore double-acting cylinder provides 56.5 N push and 42.4 N pull at 0.5 MPa, 79.2 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum push of 12 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, the proof pressure is 1.5 MPa, and the operating speed spans 30-500 mm/s.
No adjustable air cushion is featured; end-stop energy is managed solely by a fixed NBR bumper. For high kinetic energy, slow the approach or add an external shock absorber. Additionally, the unit lacks a locking mechanism, so it cannot hold a load without live air pressure and will drift if the valve is centered.
