Airtac SDA Ultra Thin Cylinder SDA12X30S
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X30S is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 30mm 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 SDA12X30S
The AirTAC SDA12X30S is a double-acting single-rod compact cylinder engineered for tight spaces. It produces a 56.5 N push and 42.4 N pull 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 riveted body design significantly reduces axial mounting depth compared to round-body alternatives.
This 12mm bore unit includes a built-in piston magnet (-S) for AirTAC reed or electronic switches. It uses a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. The 6mm rod features an M3x0.5 female thread, and the body incorporates sensor grooves for precise position detection.

Where the Airtac SDA Ultra Thin Cylinder SDA12X30S Is Used
PCB Pick & Place
Drives small suction nozzles to lift delicate electronic components, utilizing the 30mm stroke and 56.5 N force for precise placement on circuit boards.
Lab Dispenser Actuation
Moves a micro-pump head in analytical instruments where a 2.9 kg vertical lift margin is sufficient and axial depth is highly restricted.
Small Carton Flap Folding
Tucks lightweight cardboard flaps on a compact packaging line, relying on the fixed NBR bumper to absorb the end stop without adjustable cushioning.
Is the Airtac SDA Ultra Thin Cylinder SDA12X30S the Right Cylinder?
When sizing this model, consider stepping up to the SDA16, which offers 100.5 N push at 0.5 MPa if your application requires more force. As the smallest bore in the series, there is no smaller standard SDA option. To confirm your ordering essentials: specify the 12mm bore, 30mm stroke, M5x0.8 port, the required -S magnet, and the female rod thread.
Note that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. If your machine requires a held load without live pressure, you must 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 SDA12X30S FAQ
The double-acting single-rod SDA12X30S generates a push of 56.5 N and a pull of 42.4 N at 0.5 MPa. At 0.7 MPa, it pushes 79.2 N and pulls 59.4 N. The theoretical maximum push is 12 kgf at 1.0 MPa, which is the maximum operating pressure.
Yes, the -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches mounted in the body grooves. Regarding cushioning, it uses a fixed NBR bumper at each end to decelerate the stroke; it is not an adjustable air cushion, so you should slow the approach or add an external shock absorber for high-energy loads.
