This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X45S, 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 ACPD12X45S
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X45S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 45mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X45S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X45S
A double acting compact cylinder with a rod leaving both covers, the ACPD12X45S works on the 12 mm bore of AirTAC's DIN-standard ACP series and delivers 42.4 N in either direction at 0.5 MPa, because both strokes use the rod-side area. The 45 mm stroke sits inside the 50 mm standard limit for this bore, and the fitted -S magnet lets you clip CMSE or DMSE reed and solid-state switches straight onto the hard-anodized aluminium body. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and a fixed TPU bumper pads each end of travel.
The through-rod gives you a symmetric mount, resists rotation and side load, and leaves a spare rod end at the back for a sensor flag. Note that this model is discontinued: the current-production direct is the ISO 21287 ACED12X45, so confirm the mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X45S (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 ACPD12X45S Is Used
Position feedback on small slides
The fitted -S magnet with a CMSE switch reports end-of-stroke on a 45 mm slide, while the back rod carries a second flag for mid-travel detection on a lab automation axis.
Bidirectional push of light carriers
Equal 42.4 N output both ways at 0.5 MPa suits a shuttle that must push a small electronics tray in and out of a test nest without a return spring or reverse regulator trim.
Compact actuation in instrument enclosures
A body about 50% shorter in mounting length than an ISO 15552 profile cylinder fits inside a benchtop analyzer cabinet, with the M3x0.5 female rod thread taking a small fixture stud.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X45S with the ACED12X45S
At 42.4 N per side at 0.5 MPa this is the smallest ACPD bore, suited to light positioning rather than heavy clamping; step up to the 16 mm bore (75.4 N) or the 20 mm bore (117.8 N) if the load grows. The piston drifts when air is lost, so add a rod lock or pilot check if the load must stay put. The -S magnet on this unit pairs with CMSE / DMSE switches, and the discontinued status means ACED12X45 is the part to order going forward - verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ACED12X45S
- ✓ 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 ACPD12X45S FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal each way: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, peaking at 8.6 kgf at 1.0 MPa. The rod is 6 mm, the port is M5x0.8, the rod end thread is female M3x0.5, and the 45 mm stroke is within the 50 mm standard maximum for this bore. This model is discontinued; the replacement is ACED12X45.
The S means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted on the body; without the -S code there is no magnet. Before swapping to the ACED12X45, confirm the ISO 21287 mounting dimensions, since the ACP series was built to a DIN-standard footprint. The fixed TPU bumpers at both ends simply decelerate the piston and do not hold a load when air is lost.
