This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE25X5B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE25X5B 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.

The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP25X5B is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø25mm 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 ATE25X5B (ISO 21287 ACE), in the same bore, stroke and force class.
Single acting pull cylinder with spring return (discontinued): the spring extends the rod and compressed air retracts it, so the ATP25X5B rests normally extended and fails to the extended position on air loss. In the 25 mm bore this delivers a net pull of 170.9 N at 0.5 MPa (253.3 N at 0.7 MPa), already after the spring is subtracted, and it needs at least 0.2 MPa of air to overcome the spring. The B code gives a male rod thread on a 10 mm rod, and the port is M5x0.8.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body cannot. As a working rule, plan on about 102 N (roughly 10 kg of pull) for real work at 0.5 MPa instead of the full rating, and expect about 8 kg of vertical lift capability with a 2:1 margin. Note that this model is discontinued; the current-production drop-in is the ATE25X5 (swap the P for an E), so confirm the ISO 21287 mounting dimensions before swapping. This unit has no magnet fitted - the optional -S code is what enables CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE25X5B (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.
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 170.9 N |
| 0.7 MPa | 253.3 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.
| ATP | DIN compact cylinder (single-acting pull, spring-return, discontinued). |
|---|---|
| 25 | Bore size in mm. |
| ×5 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (adjustable stroke).
The spring-extended 5 mm stroke kicks finished washers or terminals out of a die pocket the moment air is lost, and the 170.9 N pull retracts the pin for the next cycle.
Normally extended by the spring, the male-thread rod holds a guard latch closed; 0.2 MPa of air pulls it open only when the line is running.
A short 5 mm pull clears a vial from a sensor position between tests, with the compact body fitting inside a tight analysis module.
Size both ways: if 170.9 N at 0.5 MPa is more than your clamp needs, the 20 mm bore (88.1 N pull at 0.5 MPa) saves space; if you need more, step up to the 32 mm bore at 296.0 N. Because the spring cannot hold a mid-stroke position, use this only where returning to the extended home position on air loss is acceptable. Match FA/FB flange, LB foot or CA/CB clevis mounting to your fixture, and order the -S code if you want CMSE / DMSE switch capability. For new designs, specify the ATE25X5 instead, as the ATP line is discontinued.
Replacement checklist
Net of the return spring, the 25 mm bore pulls 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa. It runs on 0.2-1.0 MPa (28-145 psi) of air filtered to 40 um, proof pressure is 1.5 MPa (215 psi), temperature range -20 to +70 C, speed 50-500 mm/s, rod 10 mm with male thread, port M5x0.8, and a fixed TPU bumper at both ends.
Order the ATE25X5, the current-production ISO 21287 successor: swap the P for an E and you get the same 25 mm bore, 5 mm stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, and remember the magnet is only present when the -S code is ordered.
