This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE12X5B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE12X5B 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 ATP Single Acting Port Compact Cylinder ATP12X5B
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP12X5B is a single acting, pull (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 ATE12X5B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP12X5B
A single acting pull cylinder with spring return, the ATP12X5B keeps a 12 mm bore inside an ISO 21287 compact body: the spring extends the 6 mm rod and compressed air retracts it, so the unit sits normally extended and fails to EXTENDED when air is lost. Net pull is 25.9 N at 0.5 MPa and 42.9 N at 0.7 MPa, already after the spring has taken its share; at least 0.2 MPa (28-145 psi working band) is needed to overcome the spring. This model is discontinued, and the current-production drop-in is the ATE12X5.
Because the short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, it slots into slim test fixtures and micro-assembly heads where a full-length body cannot. The B code gives a male rod thread on the 6 mm rod with a PT port, and the fixed TPU bumper at both ends simply decelerates the travel. Plan work around roughly 15 N (about 0.6 of the 25.9 N rating), which is a vertical lift margin of roughly 1 kg - enough for small caps, pins or sensor flags. Note there is no magnet fitted: the optional -S code is required before any CMSE / DMSE switch can be used.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE12X5B (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 | Pull force (spring return) |
|---|---|
| 0.5 MPa | 25.9 N |
| 0.7 MPa | 42.9 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ATP Single Acting Port Compact Cylinder ATP12X5B Is Used
Lab sample flag retraction
The 25.9 N net pull retracts a small sensor flag or shutter in a benchtop test rig, with the spring returning it to the extended home position on air loss.
Micro-assembly pin clearance
A 5 mm pull clears a locating pin inside a compact dial-table fixture, where the short ISO 21287 body fits the 50% shorter envelope.
Packaging gate latch
Spring-extend action holds a small gate closed on a cartoning line; air at 0.2 MPa or more pulls it open, and the TPU bumpers quiet both ends of travel.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP12X5B with the ATE12X5B
At 25.9 N net pull at 0.5 MPa this bore 12 unit covers light retraction tasks; step up to bore 16 (53.3 N) or bore 20 (88.1 N) if the load grows, or down is not available since 12 mm is the smallest. The 5 mm stroke sits inside the standard range for this bore, so no made-to-order stroke is needed. Match FA/FB flange, LB foot or CA/CB clevis mounts to your fixture, add the -S code only if CMSE / DMSE switching is required, and confirm ISO 21287 mounting dimensions before swapping to the ATE12X5 replacement.
Replacement checklist
- ✓ Current-production ACE → ATE12X5B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ATP Single Acting Port Compact Cylinder ATP12X5B FAQ
Net of the return spring, pull is 25.9 N at 0.5 MPa and 42.9 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), speed 50-500 mm/s, temperature -20 to +70 C, air filtered to 40 um. Bore 12 mm, stroke 5 mm, 6 mm rod with male thread (B code), M5x0.8 port, PT, fixed TPU bumper both ends, hard-anodized aluminium body with S45C hard-chrome rod.
Order the ATE12X5, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ATP follows the older DIN-standard compact format.
