This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X150S, 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 ACP12X150S
The AirTAC ACP Compact Cylinder ACP12X150S is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X150S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X150S
The ACP12X150S is a double acting DIN-standard compact cylinder with a 12 mm bore and a 150 mm rod stroke. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarding where a full-length body cannot. The 150 mm stroke is beyond the 50 mm standard limit for this bore, so it is a made-to-order build.
Because the -S code is in this model number, the magnet is fitted, and CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing. The hard-anodized aluminium body carries a fixed TPU bumper at each end, and the S45C hard-chrome rod ends in a female M3x0.5 thread. Note this model is discontinued: the current-production replacement is ACE12X150, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X150S (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 ACE12X150S 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 ACP12X150S Is Used
Ejecting small PCB carriers
The fitted -S magnet with a DMSE switch confirms each 150 mm push of a circuit-board carrier off a conveyor stop, at 56.5 N of push force at 0.5 MPa.
Light gate pusher
The short body fits inside small packaging machine frames, pushing carton flaps or dividers with 79.2 N available at 0.7 MPa.
Replacing the Airtac ACP Compact Cylinder ACP12X150S with the ACE12X150S
Size check: if 56.5 N at 0.5 MPa is marginal, step up to the 16 mm bore (100.5 N push); if it is oversized, the same bore at a shorter standard stroke may cost less. A plain cylinder drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. The 150 mm stroke is non-standard for a 12 mm bore (50 mm max standard) and is built to order. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the ISO 21287 face. This model is discontinued - order ACE12X150 as the direct successor and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE12X150S
- ✓ 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 ACP12X150S FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N; the theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting, runs 30-500 mm/s on air filtered to 40 um, and operates at 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure. The 150 mm stroke exceeds the 50 mm standard limit for a 12 mm bore, so it is made to order.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options on the ISO 21287 face. The -S code in ACP12X150S means the magnet is fitted, so CMSE or DMSE switches can be mounted. This model is discontinued; ACE12X150 is the current direct replacement - confirm the ISO 21287 mounting dimensions before ordering.
