The AirTAC SDA12X65B 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 SDA12X65B is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly reduces axial mounting depth compared to round-body units, yielding a theoretical push of 56.5 N and pull of 42.4 N at 0.5 MPa. This specific SKU features a male M5x0.8 piston rod thread for direct load coupling and operates within a 30-500 mm/s speed range.
Because the 65 mm stroke exceeds the 12 mm bore's 60 mm standard maximum, this unit is a non-standard, made-to-order configuration. The bore is hard-anodized, and end-of-travel deceleration relies strictly on fixed NBR bumpers rather than adjustable air cushions. Note that this base model lacks a piston magnet, so it cannot host reed or electronic switches without specifying the -S option.

Uses the 56.5 N extend force to push singulated circuit boards out of a routing fixture, where the short riveted body minimizes interference with routing spindles.
Drives a micro-pipette arm for fluid aspiration, leveraging the 2.9 kg vertical lift margin to move the pipette assembly smoothly at speeds up to 500 mm/s.
Actuates a lightweight diverter flap on a conveyor using the male M5x0.8 rod end, relying on fixed NBR bumpers to absorb the impact at the end of the 65 mm travel.
When sizing this 12 mm bore actuator, stepping up to the SDA16 increases your 0.5 MPa push force to 100.5 N if greater thrust is required. Ensure your ordering essentials capture this exact configuration: 12 mm bore, 65 mm non-standard stroke, M5x0.8 port, male M5x0.8 rod thread, and no sensor magnet. Since a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, apply an external rod lock or pilot-operated check valve if the mechanism must hold a load safely without live pressure.
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 increases to 79.2 N. The theoretical maximum push is 12 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger reed or electronic switches. You must select the -S option code to add a magnet for sensing. Additionally, end-stop deceleration is handled by fixed NBR bumpers, not an adjustable air cushion.
