The AirTAC SDA12X65N Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 65mm 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 SDA12X65N is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial mounting depth where standard round bodies cannot fit, delivering a 56.5 N push at 0.5 MPa. This specific 65 mm stroke unit is a non-standard, made-to-order configuration exceeding the 60 mm maximum standard stroke for this 12 mm bore.
A fixed NBR bumper at each end decelerates the piston near stroke termination, but it is not an adjustable air cushion. This model lacks a piston magnet and cannot support sensing switches. Operating speed spans 30-500 mm/s, driven through an M5x0.8 port, while the 6 mm rod uses an M3x0.5 female thread end.

Provides the 56.5 N extension force needed to lower test probes onto printed circuit boards within shallow automated test fixtures.
Pushes lightweight plastic components out of molding dies, utilizing the 6 mm rod and 65 mm travel to clear the tooling envelope.
Drives a metering valve for micro-fluidic chemical dispensing, where the fixed NBR bumper softens the end stop without requiring external cushions.
When sizing this unit, stepping up to the SDA16 increases the 0.5 MPa push force to 100.5 N, whereas this 12 mm bore provides a lighter 56.5 N. Because a plain compact cylinder drifts when air pressure is lost or the valve is centered, applications requiring suspended load holding need an external rod lock or pilot-operated check valve. To order, confirm the 12 mm bore, 65 mm non-standard stroke, M5x0.8 port, female rod thread, and no magnet.
Quick checklist
At 0.5 MPa, the push force is 56.5 N and the pull force is 42.4 N. At 0.7 MPa, the push is 79.2 N and the pull is 59.4 N. The theoretical maximum push is 12 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the -S option variant to enable sensing. Additionally, the end stops use fixed NBR bumpers rather than adjustable air cushions, so high-speed approaches may require external shock absorption.
