The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X45 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 SDA12X45 is a double-acting single-rod compact cylinder engineered for tight machinery layouts. It provides 56.5 N of push force and 42.4 N of pull force at 0.5 MPa, yielding a safe working load of roughly 34 N or a 2.9 kg vertical lift with a 2:1 margin. The 45 mm stroke operates within the 12 mm bore's 60 mm standard limit, ensuring standard delivery.
Its riveted body significantly reduces axial mounting depth compared to round-body units, while the hard-anodized bore extends service life. End stops rely on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers are recommended for high-energy cycles. This specific SKU lacks a piston magnet, so it cannot host magnetic switches.

Drives delicate pneumatic test pins onto printed circuit boards, utilizing the 56.5 N push force to ensure reliable electrical contact without damaging the substrate.
Moves micro-fluidic valves or syringe heads in compact diagnostic equipment where the 45 mm stroke and minimal axial footprint are critical for fitting inside small enclosures.
Ejects tiny plastic components from injection mold cavities, using the 6 mm rod and fixed NBR bumper to safely complete the 45 mm travel at cycle speeds up to 500 mm/s.
If you need slightly more thrust, stepping up to the SDA16 increases output to 100.5 N at 0.5 MPa, while the SDA12 represents the smallest available bore in this series. When sizing this 12 mm unit, remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the piston near the stroke end and does not function as a locking brake. To suspend a load safely without live pressure, incorporate an external rod lock or a pilot-operated check valve. To order, confirm the 12 mm bore, 45 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the absence of the magnet option.
Quick checklist
This 12 mm bore double-acting cylinder outputs 56.5 N push and 42.4 N pull at 0.5 MPa, increasing to 79.2 N push and 59.4 N pull at 0.7 MPa. The theoretical maximum push is 12 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. If your application requires position sensing, you must select the SDA12X45S variant, which includes the built-in magnet for switch grooves.
