This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X20S, 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 ACPD12X20S
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X20S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X20S
A double acting compact cylinder with a rod leaving both covers, the ACPD12X20S delivers 42.4 N in each direction at 0.5 MPa (59.4 N at 0.7 MPa) because both strokes work on the rod-side area of the 12 mm bore. The 20 mm stroke sits well inside the 50 mm standard limit for this bore, and the M5x0.8 ports suit small pneumatic manifolds. Its hard-anodized aluminium body is an ISO 21287 short build, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder.
The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag in a tight fixture. Because the S code is in this model, the magnet is fitted, so CMSE or DMSE reed and solid-state switches mount directly on the body. A fixed TPU bumper pads each end of travel, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note this model is discontinued: the current direct is the ACED12X20, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X20S (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 ACPD12X20S Is Used
PCB push-off station
The fitted magnet and CMSE switch confirm end position as the through-rod ejects finished circuit boards from a test nest at 42.4 N per side.
Lab sample indexer
A 20 mm stroke and M5x0.8 ports make this compact body ideal for stepping microplate trays between assay stations on a benchtop analyzer.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X20S with the ACED12X20S
At 42.4 N per side at 0.5 MPa this 12 mm bore suits light clamping, sorting and positioning tasks; step down is not available below 12 mm, while the 16 mm bore gives 75.4 N if you need more. The through-rod gives a symmetric mount and the female M3x0.5 rod thread accepts standard I/Y knuckles. The magnet is fitted here (the -S option), enabling CMSE / DMSE switches. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. This model is discontinued - order the ACED12X20 as the current ISO 21287 replacement and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED12X20S
- ✓ 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 ACPD12X20S FAQ
Because a rod exits both covers, force is equal in both directions: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a maximum of about 8.6 kgf at 1.0 MPa. Both strokes use the rod-side area of the 12 mm bore, so push and pull are identical. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and guards. The S code means the magnet is fitted, letting CMSE or DMSE reed or solid-state switches sense stroke position. A fixed TPU bumper pads each end, and the model is discontinued - the ACED12X20 is the current replacement.
