Airtac SDA Ultra Thin Cylinder SDA12X15N
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X15N is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 15mm 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 SDA12X15N
The AirTAC SDA12X15N is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It delivers a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa, yielding a safe working load of roughly 34 N (about 60% of the 0.5 MPa push figure) and a vertical lift capacity of 2.9 kg with a 2:1 safety margin. The 12 mm bore uses an M5x0.8 port and a 6 mm piston rod.
A fixed NBR bumper at each end decelerates the piston near the stroke limits, functioning as an end-stop rather than a field-adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot host AirTAC reed or electronic switches. If your sequence requires position feedback, you must select the -S variant instead.

Where the Airtac SDA Ultra Thin Cylinder SDA12X15N Is Used
PCB Ejector Pins
Provides the 56.5 N push at 0.5 MPa needed to pop delicate printed circuit boards out of test fixtures without damaging traces.
Lab Dispenser Valving
Acts as a compact 15 mm stroke gate for micro-fluidic dispensing heads, fitting into cramped multi-head analytical equipment arrays.
Small Part Sorting Diverters
Pushes lightweight plastic components down conveyor chutes with a safe working load of 34 N, ensuring gentle but positive diversion.
Is the Airtac SDA Ultra Thin Cylinder SDA12X15N the Right Cylinder?
When sizing this 12 mm bore actuator, consider stepping up to the SDA16 if your application requires more thrust, as the 16 mm bore provides 100.5 N of push force at 0.5 MPa compared to the 56.5 N offered here. As the smallest bore in the SDA series, there is no smaller standard option downward. To finalize your order, confirm the 12 mm bore, 15 mm stroke, M5x0.8 port, female M3x0.5 rod-end thread, and the absence of a piston magnet. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only slows the piston near the end of travel and does not act as a locking brake. To hold a load securely without live pressure, 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 SDA12X15N FAQ
This double-acting 12 mm bore cylinder outputs 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. It operates between 0.15 and 1.0 MPa, tolerates temperatures from -20 to +70 C, and cycles at speeds of 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to order the -S variant to utilize the magnetic switch grooves machined around the riveted body.
