This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE12X5B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE12X5B 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 ASP Single Acting Guided Compact Cylinder ASP12X5B
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP12X5B is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø12mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE12X5B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP12X5B
The ASP12X5B is a single acting push cylinder with spring return: air extends the 6 mm rod and the internal spring retracts it, so only one air line is needed. This 12 mm bore delivers 40 N of push at 0.5 MPa (62.7 N at 0.7 MPa), already net of the spring, and it needs just 0.2 MPa to overcome the spring and start moving. It is discontinued - order the ASE12X5, the current ISO 21287 successor in the same bore, stroke and force class.
The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why this size fits inside slim test fixtures and micro-assembly heads. Because the 40 N push at 0.5 MPa equals about 4 kgf, plan on roughly 2 kg of vertical lift with a 2:1 margin. The B code gives a male rod thread and a PT port; the -S magnet for CMSE / DMSE switches is optional and not fitted on this code.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE12X5B (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 (spring return) |
|---|---|
| 0.5 MPa | 40.0 N |
| 0.7 MPa | 62.7 N |
Single-acting push: air extends the rod; the return spring retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ASP Single Acting Guided Compact Cylinder ASP12X5B Is Used
Micro pin ejection
The 5 mm stroke and 40 N push at 0.5 MPa eject a dowel pin or blank from a small fixture die in one quick tap, with the spring pulling the rod back instantly for the next cycle.
Part presence check
In an electronics assembly head, the short body probes whether a connector is seated; order the -S magnet version to add a CMSE or DMSE switch for a go / no-go signal.
Light clamping in tight cells
At about half the installed length of an ISO 15552 profile cylinder, this 12 mm unit clamps small PCB brackets inside a compact jig where a full-length body will not fit.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP12X5B with the ASE12X5B
At 40 N push at 0.5 MPa this bore suits light ejection and part-present tasks; step up to the 16 mm bore (78.4 N at 0.5 MPa) if the load creeps up, or down to nothing smaller since 12 mm is the smallest in the family. Remember the spring returns the rod home on air loss - it will not hold a mid-stroke position. Match LB foot or FA/FB flange brackets to your fixture, add the -S code only if you need CMSE / DMSE sensing, and confirm ISO 21287 mounting dimensions before swapping to the ASE12X5.
Replacement checklist
- ✓ Current-production ACE → ASE12X5B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ASP Single Acting Guided Compact Cylinder ASP12X5B FAQ
Push force, already net of the return spring, is 40 N at 0.5 MPa and 62.7 N at 0.7 MPa. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, air filtered to 40 um, speed 50-500 mm/s, temperature -20 to +70 C. The 6 mm rod carries a male thread (B code) and the port is M5x0.8 with PT body thread.
Only if you order the optional -S magnet code - this ASP12X5B has no magnet, so no switch can be mounted as-is. With -S, AirTAC CMSE or DMSE reed or solid-state switches sense end positions. Also note the model is discontinued; the ASE12X5 is the current drop-in, so confirm ISO 21287 mounting dimensions before you swap.
