This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X90S, 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 ACPD Double Rod Compact Cylinder ACPD12X90S
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X90S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X90S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X90S
A double acting compact cylinder with a rod leaving both covers, the ACPD12X90S pushes and pulls with identical output: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa in each direction, because both strokes work on the rod-side area. The 12 mm bore drives a 6 mm through-rod over a 90 mm stroke, with a fixed TPU bumper at each end and M5x08 ports - note the port is M5x0.8. Because the piston rod passes through both covers, it resists rotation and side load and the rear rod can carry a sensor flag.
The hard-anodized aluminium body keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, so it slots into tight fixtures. The 90 mm stroke is longer than the 50 mm standard maximum for this bore, so it is a made-to-order build. This model carries the optional -S magnet, so CMSE or DMSE switches can be mounted directly. The ACPD family is discontinued; the current-production direct is the ACED12X90 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X90S (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD12X90S Is Used
Two-position part presence flag
The rear rod carries a flag past a CMSE or DMSE switch to confirm a PCB magazine or small tray has fully seated, with equal 42.4 N return force.
Light electronics fixture clamp
Clamps connector housings or small die-cast covers on an SMT bench fixture; about 25 N of practical force at 0.5 MPa is enough for delicate parts.
Symmetric push-pull gate
Slides a small guard or indexing shuttle where identical force in both directions matters - the double rod delivers 59.4 N at 0.7 MPa either way.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X90S with the ACED12X90S
At 42.4 N per side at 0.5 MPa this 12 mm bore suits light clamping and sensing tasks; step up to the 16 mm bore (75.4 N) or 20 mm bore (117.8 N) if the load needs more margin. The through-rod gives a symmetric mount and the female M3x0.5 rod thread accepts standard knuckles. Remember the piston drifts if air is lost - add a rod lock or pilot check where a load must stay put. Order the ACED12X90 instead: it is the current ISO 21287 successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACED12X90S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD12X90S FAQ
Yes - as a double-rod cylinder both strokes use the rod-side area, so force is equal each way: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a maximum of 8.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 90 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
This model is discontinued; the current-production replacement is the ACED12X90 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 short-body format - confirm the mounting dimensions before swapping since the ACP was DIN-standard. On this unit the -S magnet is fitted, so CMSE or DMSE reed or solid-state switches mount directly; on a new order the magnet is an optional code, not standard.
