Airtac SDA Ultra Thin Cylinder SDA12X10S
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X10S is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 10mm 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.

About the Airtac SDA Ultra Thin Cylinder SDA12X10S
The AirTAC SDA12X10S is a double-acting, single-rod compact cylinder engineered for tight spaces. It delivers 56.5 N of push force and 42.4 N of pull force at 0.5 MPa. The short riveted body drastically reduces axial mounting depth compared to round-body alternatives, making it ideal for dense machinery layouts.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It features a 6 mm piston rod, an M5x0.8 air port, and relies on a fixed NBR bumper at each end to absorb end-stop impact rather than an adjustable air cushion.

Where the Airtac SDA Ultra Thin Cylinder SDA12X10S Is Used
PCB Ejector Pins
Provides the 56.5 N push needed to pop delicate printed circuit boards out of test fixtures without damaging traces.
Lab Dispenser Valving
Actuates small fluid nozzles in automated analytical equipment where the 10 mm stroke and compact depth fit cramped enclosures.
Micro-Gripper Actuation
Drives tiny mechanical fingers in electronics assembly handlers, using the built-in magnet for precise end-of-travel confirmation.
Is the Airtac SDA Ultra Thin Cylinder SDA12X10S the Right Cylinder?
This 12 mm bore generates 56.5 N push at 0.5 MPa, yielding a safe working load around 34 N (roughly 60% capacity) and a vertical lift capability of approximately 2.9 kg with a 2:1 safety margin. If your application requires slightly more force, stepping up to the SDA16 provides 100.5 N of push at 0.5 MPa. Since 12 mm is the smallest available SDA bore, there is no smaller option in this series.
When ordering, confirm the 10 mm stroke, M5x0.8 port, and the female M3x0.5 rod-end thread. Because this is a double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered—the piston drifts, and the fixed bumper only decelerates near the stroke end. For position holding, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA12X10S FAQ
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 force is 79.2 N and the pull force is 59.4 N. The theoretical maximum push force is 12 kgf at the maximum operating pressure of 1.0 MPa.
No adjustable air cushion is available; a fixed NBR bumper absorbs impact at the stroke ends. Additionally, the piston drifts if air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is required to hold a load.
