This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X45-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X45-30S 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 ACPJ12X45-30S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X45-30S is a double acting, adjustable stroke 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 ACEJ12X45-30S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X45-30S
A double acting compact cylinder with an adjustable extend stroke, the ACPJ12X45-30S carries a 12 mm bore, a 45 mm stroke and a 30 mm trim window, so an external stop screw lets you set any usable extend length from 15 to 45 mm on site. Air pushes the rod out at 56.5 N and pulls it back at 42.4 N at 0.5 MPa; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. The hard-anodized aluminium body and S45C hard-chrome rod keep the short ISO 21287-class footprint, which saves about 50% of the mounting length of an ISO 15552 profile cylinder.
Because the -S code is ordered, the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke signalling. Plan on roughly 34 N of real work at 0.5 MPa (about 60% of the rated push), which lifts about 3 kg vertically with a 2:1 margin - enough for small covers, chutes or sensor carriages. Note this model is discontinued: the current-production drop-in is the ACEJ12X45, and buyers should confirm ISO 21287 mounting dimensions before swapping, since the ACP series was built to a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X45-30S (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 | 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 ACEJ12X45-30S 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 ACPJ12X45-30S Is Used
Signalled ejection on a small assembly station
The fitted magnet drives a CMSE switch to confirm each 15-45 mm push-off of a finished part from a nest, with 56.5 N of push at 0.5 MPa ample for lightweight components.
Trim-to-fit gate on a laboratory sample feeder
The 30 mm adjustment window lets a technician dial the extend stroke between 15 and 45 mm to match different tray pitches without changing the cylinder.
Low-force clamping inside a compact fixture
About 34 N of usable force at 0.5 MPa secures thin PCBs or small brackets in a jig where the short body, roughly half the length of an ISO 15552 profile cylinder, is the only actuator that fits.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X45-30S with the ACEJ12X45-30S
At 12 mm bore this is the smallest force class in the family: 56.5 N push at 0.5 MPa. Step up to the 16 mm bore for 100.5 N push at the same pressure, or drop to a direct-acting mini actuator if even 56.5 N is more than the job needs. The 30 mm window trims the 45 mm extend stroke down to 15 mm minimum; it is a mechanical end stop only, so on air loss the piston still drifts and it must never be relied on to hold a load. FA/FB flange and LB foot mountings plus I/Y rod knuckles bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. For new builds, order the ACEJ12X45 instead - same bore, stroke and force class, currently in production.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X45-30S
- ✓ 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 ACPJ12X45-30S FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is double acting with a 45 mm stroke trimmed by a 30 mm window (usable 15-45 mm), an M5x0.8 port, a female M3x0.5 rod thread, a 6 mm rod, fixed TPU bumpers at both ends, speed 30-500 mm/s, air filtered to 40 um, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi) and a -20 to +70 C temperature range.
Order the ACEJ12X45, the current-production ISO 21287 successor: swap the P for an E and you get the same 12 mm bore, 45 mm stroke and force class in a matching short body. Because the ACP series followed a DIN-standard footprint, confirm the ISO 21287 mounting dimensions against your fixture before swapping. The ACEJ also carries the optional -S magnet code for CMSE / DMSE switches, and FA/FB flange, LB foot and I/Y knuckle accessories bolt to its standard face.
