The AirTAC SDA12X50B 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 SDA12X50B is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, the overall axial length is drastically reduced compared to round-body alternatives. Delivering 56.5 N of push force at 0.5 MPa, it handles light-duty positioning with a 50 mm stroke.
This specific SKU features a male M5x0.8 threaded piston rod for straightforward load coupling, overriding the default female M3x0.5 thread. The 12 mm bore utilizes an M5x0.8 port and relies on a fixed NBR bumper at each end to decelerate the stroke end—this is not an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot support AirTAC reed or electronic switches.

Thread: PT standard. Related SDA-family variants: SSA (single-acting push), STA (single-acting pull), SDAD (double rod), SDAJ (adjustable stroke), SDAT (duplex), SDAW (duplex-end).
Drives delicate test probes against printed circuit boards, where the 56.5 N push force at 0.5 MPa is sufficient for contact without damaging the substrate.
Indexes a 50 mm stroke to trigger micro-fluidic valve dispensers in analytical instruments, taking advantage of the minimal axial mounting depth.
Pushes lightweight plastic components out of pick-and-place nests using the male M5x0.8 rod end to attach a custom soft-tip ejector finger.
When sizing this 12 mm bore actuator, evaluate your force margins carefully. If your application requires slightly more thrust, stepping up to the SDA16 increases the push force to 100.5 N at 0.5 MPa. As the smallest bore in the SDA series, there is no smaller standard option available.
For ordering and integration, confirm the essentials: a 12 mm bore, 50 mm stroke, M5x0.8 port, and the -B male M5x0.8 rod thread. Keep in mind that a plain compact cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. If your application must maintain a load without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 12 mm bore 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 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 supports a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S magnet option, so it cannot support AirTAC reed or electronic switches. Additionally, it relies on a fixed NBR bumper to decelerate at stroke ends rather than an adjustable air cushion; for high-energy cycles, you should slow the approach or add an external shock absorber.
