This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X200-30S, 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 ACPJ Adjustable Compact Cylinder ACPJ12X200-30S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X200-30S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 200mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X200-30S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-30S
This AirTAC ACPJ12X200-30S is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 200 mm stroke by up to 30 mm on site, giving a usable range of 170-200 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 / 59.4 N at 0.7 MPa), running on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-500 mm/s. Note that the 200 mm stroke exceeds the 50 mm standard for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures where a full-length body cannot. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing. Rule of thumb for sizing: expect about 34 N of usable work at 0.5 MPa, which lifts roughly 2.9 kg vertically with a 2:1 margin. This model is discontinued; the current-production drop-in is ACEJ12X200, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X200-30S (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 |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-30S Is Used
Position-confirm gate on a small assembly cell
The fitted -S magnet lets a CMSE switch signal gate-open at the trimmed 170-200 mm position, while the 56.5 N push at 0.5 MPa is ample for a lightweight sliding guard.
Light-duty ejection of plastic caps
About 34 N of usable force at 0.5 MPa nudges small molded caps off a chute, and the 30 mm adjustment window lets the operator fine-tune the eject point without re-piping.
Sample pusher in a compact lab analyzer
The short body, roughly 50% shorter than an ISO 15552 profile cylinder, fits inside tight instrument housings, and the M3x0.5 female rod thread accepts a small custom pusher plate.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-30S with the ACEJ12X200-30S
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa versus 100.5 N for the 16 mm bore and 157.1 N for the 20 mm. Choose it for light clamps, gates and sensors under about 34 N of real load; step up a bore if your part weight or friction is higher. The 30 mm window only shortens the extend stroke (170-200 mm here) and acts as a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. Discontinued: order ACEJ12X200 as the current replacement and verify ISO 21287 dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X200-30S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-30S FAQ
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 maximum of 11.5 kgf at 1.0 MPa. It is double acting, runs 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air, tolerates -20 to +70 C, uses an M5x0.8 port and an M3x0.5 female rod thread, and carries fixed TPU bumpers at both ends. The 200 mm stroke is a non-standard, made-to-order length for this 12 mm bore.
The -30 code means a stop screw shortens the extend stroke by up to 30 mm, so the rod travels anywhere in a 170-200 mm window; it cannot lengthen the stroke past 200 mm. The stop is a mechanical end stop only and does not hold a load if air is lost. This ACPJ is discontinued; the current-production drop-in is ACEJ12X200 in the same bore, stroke and force class, but confirm the ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.
