This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X15S, the same code under the new prefix. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACP Compact Cylinder ACP12X15S
The AirTAC ACP Compact Cylinder ACP12X15S is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X15S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X15S
A double acting compact cylinder in the DIN-standard ACP series, the ACP12X15S pairs a 12 mm bore with a 15 mm stroke and ships with the optional -S magnet already fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N push at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa.
The short ISO 21287-class body cuts mounting length by roughly half versus an ISO 15552 profile cylinder, which is why it suits slim fixtures, small gates and tight jigs. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and this model is discontinued: the current-production direct is the ACE12X15, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X15S (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACE12X15S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP12X15S Is Used
PCB push-off station
Ejects finished circuit boards from a test nest on an SMT line; 56.5 N at 0.5 MPa is ample for a 100 g board, and the fitted -S magnet feeds a CMSE switch to confirm ejection.
Micro part gating
Swings a small deflector across a pharma tablet chute between batches; the 15 mm stroke matches the chute width and the 42.4 N pull retracts the gate reliably.
Label head lift
Raises a lightweight print-and-apply label head about 1.7 kg with margin; the compact body tucks under the conveyor frame where a full-length cylinder would not fit.
Replacing the Airtac ACP Compact Cylinder ACP12X15S with the ACE12X15S
At 12 mm bore this is the smallest ACP size: 56.5 N push at 0.5 MPa against 100.5 N from a 16 mm bore and 157.1 N from a 20 mm bore. Step up one size if your part weight or clamp force sits near the limit, or drop to direct-acting linkages if 56.5 N is generous. The 15 mm stroke sits well inside the 50 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. The fitted -S magnet lets CMSE / DMSE switches report position; the female M3x0.5 rod thread accepts I/Y knuckles. Note that a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must hold. Order the ACE12X15 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE12X15S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP12X15S FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is a double acting 12 mm bore, 15 mm stroke unit with a 6 mm rod, M5x0.8 port, female M3x0.5 rod thread, operating range 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s and a fixed TPU bumper at both ends.
Order the ACE12X15, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same bore, stroke and force class and takes the same FA/FB flange, LB foot and CA/CB clevis brackets, but because the ACP was built to a DIN standard you should confirm the ISO 21287 mounting dimensions before committing the swap.
