Airtac SDA Ultra Thin Cylinder SDA12X10H
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X10H 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 SDA12X10H
The AirTAC SDA12X10H is a double-acting single-rod compact cylinder engineered for extremely tight machinery. It features a 12mm bore and 10mm stroke, generating 56.5 N of push force and 42.4 N of pull force at 0.5 MPa. The short riveted body significantly reduces axial mounting depth compared to round-body alternatives, making it ideal for space-constrained footprints. This H variant utilizes a fluororubber (FKM) seal for enhanced thermal and oil resistance.
Equipped with a 6mm piston rod and an M5x0.8 air port, this model operates at speeds between 30 and 500 mm/s. It relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot directly host magnetic switches; the -S variant is required for reed or electronic switch sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA12X10H Is Used
PCB Pick & Place
Drives a tiny 10mm stroke to position micro-suction nozzles for electronic component placement on dense printed circuit board assembly lines.
Lab Dispenser Valve
Actuates a precision reagent dispensing head where the FKM seal resists chemical exposure and the compact body fits inside analytical instruments.
Micro-Part Ejection
Pushes small plastic or metal connectors out of an injection mold cavity, utilizing 56.5 N of push force at 0.5 MPa within a narrow machine frame.
Is the Airtac SDA Ultra Thin Cylinder SDA12X10H the Right Cylinder?
When sizing this 12mm bore actuator, stepping up to the SDA16 increases the 0.5 MPa push force to 100.5 N for heavier loads. A safe working load for the SDA12 is approximately 34 N (about 60% of its 56.5 N capacity), yielding a vertical lift capability of roughly 2.9 kg with a 2:1 safety margin. 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, and the fixed bumper only decelerates near the stroke end. For secure load holding, an external rod lock or pilot-operated check valve is required. To order, confirm the 12mm bore, 10mm stroke, M5x0.8 port, female M3x0.5 rod thread, and FKM seal.
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 SDA12X10H FAQ
This double-acting 12mm bore cylinder provides 56.5 N push and 42.4 N pull at 0.5 MPa, 79.2 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum push of 12 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the speed range is 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You must select the -S option code to enable magnetic sensing. Additionally, end-stop deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
