This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE12X5SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE12X5SB 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 ATP12X5SB 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 ATE12X5SB (ISO 21287 ACE), in the same bore, stroke and force class.
The ATP12X5SB is a single acting pull cylinder with spring return: the spring extends the 6 mm rod and compressed air retracts it, so the rod sits normally extended and fails to the extended position on air loss. In the 12 mm bore class it delivers 25.9 N of pull at 0.5 MPa and 42.9 N at 0.7 MPa, both figures already net of the return spring, and it needs at least 0.2 MPa of air to overcome the spring. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted directly on the body, and the B code gives a male rod thread instead of the standard female version.
The short ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this size fits inside slim fixtures, small gating slides and tight sensor stations. A practical sizing rule: at 0.5 MPa plan on roughly 15 N of real working pull (about 60% of the rating), which corresponds to lifting about 1.3 kg vertically with a 2:1 margin. Note that this model is discontinued; the current-production drop-in is the ATE12X5, and you should confirm the ISO 21287 mounting dimensions before swapping, since the ATP follows the older DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE12X5SB (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 | 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.
| ATP | DIN compact cylinder (single-acting pull, spring-return, discontinued). |
|---|---|
| 12 | 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 5 mm pull stroke and the fitted -S magnet let a CMSE switch confirm a small part or clamp has reached its home position on a compact assembly station, with the spring guaranteeing the extended rest state on air loss.
In electronics fixture work, the 25.9 N spring-extended pin lifts or releases a light component (about 1.3 kg with a 2:1 vertical margin) the moment air is removed, a natural fail-safe for manual load stations.
Analytical and packaging lab devices use the 5 mm air-retracted motion at 0.2-1.0 MPa (28-145 psi) to clear a sensor window or release a latch, where the M5x0.8 port and tiny body fit inside the housing.
At 5 mm stroke this is a micro-positioning actuator, not a work cylinder. If 25.9 N at 0.5 MPa is marginal, step up to the 16 mm bore (53.3 N at 0.5 MPa); if you need less force and the shortest possible body, there is no smaller bore in the family, so check the ATE range instead. Because the spring returns the rod and no mid-stroke position is held, use it only where full retraction to the extended home position is acceptable. Match the mounting to your fixture with FA/FB flange, LB foot or CA/CB clevis brackets, and remember the -S magnet on this model is what enables CMSE / DMSE switch mounting. Order the ATE12X5 as the current replacement and verify the ISO 21287 mounting dimensions first.
Replacement checklist
It is a single acting pull cylinder: the spring extends the rod, air retracts it. Pull force is 25.9 N at 0.5 MPa and 42.9 N at 0.7 MPa, both net of the return spring, with a minimum working pressure of 0.2 MPa. For real work at 0.5 MPa, plan on about 15 N (roughly 60% of the rating), which is about 1.3 kg of vertical lift with a 2:1 margin. Operating range is 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), speed 50-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The ATP is an ISO 21287 compact cylinder with a hard-anodized aluminium body and S45C hard-chrome rod; its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length actuator will not. Both ends carry a fixed TPU bumper that simply decelerates the rod at the ends of travel. The ATP12X5SB is discontinued - the current-production drop-in is the ATE12X5 (same 12 mm bore, 5 mm stroke and force class). Confirm the ISO 21287 mounting dimensions before swapping, because the ATP follows the older DIN-standard footprint.
