This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X150-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X150-100S in place of this model. 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 ACPJ12X150-100S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-100S is a double acting, adjustable stroke 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 ACEJ12X150-100S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-100S
A double acting compact cylinder with an adjustable extend stroke, the ACPJ12X150-100S carries a 12 mm bore and a 150 mm stroke trimmed by a 100 mm stop-screw window, so the effective range is 50-150 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N push at 0.7 MPa. The 150 mm stroke exceeds the 50 mm standard limit for bore 12, so it is a made-to-order build. Note this model is discontinued: the current-production drop-in is ACEJ12X150, same bore, stroke and force class.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim pick-and-place heads and guarded test rigs. The -S magnet is fitted on this unit, so CMSE / DMSE reed or solid-state switches can be clamped on for end-of-stroke signals. As a buyer rule of thumb, plan on roughly 34 N of usable push at 0.5 MPa (about 60% of rating), which lifts about 2.9 kg vertically with a 2:1 margin. A fixed TPU bumper sits at each end; the stop screw sets stroke length but never holds a load if air is lost.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X150-100S (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 ACEJ12X150-100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-100S Is Used
Small-part ejection on assembly stations
The 56.5 N push at 0.5 MPa clears finished micro-components from nests, and the 50-150 mm adjustable range lets one station handle multiple part heights without swapping cylinders.
Sample indexing in compact lab analysers
With the fitted -S magnet driving CMSE switches, the 150 mm stroke positions sample trays inside tight analyser housings where a full-length profile cylinder cannot fit.
End-of-stroke confirmation on gated chutes
DMSE solid-state switches on the magnet flag gate-open position on packaging chutes, while the stop screw trims the gate swing to match each carton size.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-100S with the ACEJ12X150-100S
Size against neighbours: bore 10-class small cylinders fall well under the 56.5 N push of this 12 mm bore at 0.5 MPa, while bore 16 gives 100.5 N push at the same pressure if your fixture needs more margin. The 100 mm window suits machines where one cylinder must serve several product lengths. FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Because the adjuster is a mechanical end stop, not a mid-stroke lock, add a separate valve or brake if the load must stay put on air loss. Order ACEJ12X150 as the current replacement and confirm ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X150-100S
- ✓ 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 ACPJ12X150-100S FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting, 12 mm bore, 150 mm stroke with a 100 mm adjustment window (usable 50-150 mm), M5x0.8 ports, female M3x0.5 rod thread, 0.15-1.0 MPa (22-145 psi) operating range, 30-500 mm/s speed and a fixed TPU bumper at both ends. The 150 mm stroke is made to order since bore 12 standard tops out at 50 mm.
No - the ACPJ family is discontinued. Order ACEJ12X150 instead: swap the P for an E and you get the current-production ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before redesigning your fixture.
