Airtac ATE Single Acting Guided Compact Cylinder ATE12X5S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE12X5S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø12mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ATE Single Acting Guided Compact Cylinder ATE12X5S
This ATE12X5S is a single acting pull cylinder, where the spring extends the rod and air retracts it, with forces already net of the spring. The 12 mm bore delivers a 25.9 N pull at 0.5 MPa, suitable for light clamping or indexing tasks in tight spaces.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting length. With the optional -S magnet fitted, you can add CMSE or DMSE switches for position sensing, and the fixed TPU bumper at both ends absorbs end-of-stroke energy without adjustment.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø12mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 25.9 N |
| 0.7 MPa | 42.9 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa. Single-acting strokes are short (Ø12 to 10 mm, Ø16-100 to 25 mm).

Where the Airtac ATE Single Acting Guided Compact Cylinder ATE12X5S Is Used
Jig Clamping
Use the 25.9 N pull to retract a small clamp pin in a CNC fixture, freeing the operator's hands for part loading in a compact workcell.
Tight Gantry Stop
Mount this 5 mm stroke cylinder on a pick-and-place gantry to pull a locating pin clear of a pallet, fitting where a full-length cylinder would not.
Position Feedback
With the -S magnet, fit a CMSE switch to confirm the rod is fully retracted before a downstream process starts, ensuring sequence reliability in automated assembly.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE12X5S the Right Cylinder?
For a lighter pull, consider the ATE16X25S with 53.3 N at 0.5 MPa, or step up to the ATE20X25S for 88.1 N if you need more force. This 5 mm stroke is ideal for short, precise movements; the spring returns the rod to its extended home position on air loss, but it does not hold a mid-stroke load. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Single-acting: do not force the rod against the spring.
- check Installation by qualified personnel per AirTAC docs.
Airtac ATE Single Acting Guided Compact Cylinder ATE12X5S FAQ
The pull force is 25.9 N at 0.5 MPa and 42.9 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi).
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight jigs and guards. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
