Airtac SDA Ultra Thin Cylinder SDA12X15S
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X15S 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 SDA12X15S
The AirTAC SDA12X15S is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly merges the barrel, rear cover, piston, and rod to minimize axial mounting depth, outperforming standard round-body units where space is constrained. At 12mm bore, it generates 56.5 N of push force and 42.4 N of pull force at 0.5 MPa.
This unit includes the S option, meaning a built-in piston magnet enables position detection via an AirTAC reed or electronic switch housed in the body grooves. The 6mm piston rod features an M3x0.5 female thread, and end-stops rely on a fixed NBR bumper rather than an adjustable air cushion. With a safe working load around 34 N (roughly 60% of the 0.5 MPa push figure), it is ideal for low-mass positioning tasks.

Where the Airtac SDA Ultra Thin Cylinder SDA12X15S Is Used
PCB Edge-Guiding
Shifts thin electronic circuit boards laterally on a pick-and-place conveyor using a lightweight 56.5 N push force without crowding the routing head.
Lab Dispenser Pinching
Actuates a small fluid pinch-valve in diagnostic equipment where a short 15mm stroke and compact body footprint are critical for dense packaging.
Small Part Ejection
Pushes miniature plastic components out of an injection mold cavity, utilizing the M3x0.5 female rod thread for easy mounting of a custom soft-tip ejector pin.
Is the Airtac SDA Ultra Thin Cylinder SDA12X15S the Right Cylinder?
When sizing this 12mm bore actuator, sizing down is not an option as this is the smallest available SDA series diameter. If your application requires slightly more force, stepping up to the SDA16 increases the 0.5 MPa push capacity to 100.5 N. For this SDA12X15S configuration, confirm your ordering essentials: 12mm bore, 15mm stroke, M5x0.8 port, built-in magnet (S), and female rod thread.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke end without acting as a lock. If your setup demands vertical position holding, such as lifting a 2.9 kg mass with a 2:1 safety margin, 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 SDA12X15S FAQ
This 12mm bore double-acting cylinder provides 56.5 N push and 42.4 N pull at 0.5 MPa, and 79.2 N push at 0.7 MPa. The theoretical maximum push force is 12 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No, it uses a fixed NBR bumper at each end to decelerate the stroke end, which is not a field-adjustable air cushion. This specific model has a female M3x0.5 rod thread (a male M5x0.8 thread requires the B option). The S suffix means it has a piston magnet ready for an AirTAC reed or electronic switch.
