This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE32X20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE32X20 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 ATP32X20 is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE32X20 (ISO 21287 ACE), in the same bore, stroke and force class.
The ATP32X20 is a single acting pull cylinder: a spring extends the rod to its home position and compressed air retracts it, so the actuator is normally extended at rest and fails to the extended state when air is lost. This 32 mm bore, 20 mm stroke unit delivers 296 N of pull at 0.5 MPa (434.2 N at 0.7 MPa), figures already net of the return spring, and needs at least 0.2 MPa to overcome the spring. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarded assemblies. Note: the ATP family is discontinued; the current-production drop-in is the ATE32X20.
Practical sizing: plan on roughly 178 N of real work at 0.5 MPa rather than the full 296 N rating, which is about 15 kg of vertical pull with a 2:1 margin. The hard-anodized aluminium body carries a fixed TPU bumper at both ends, and the 12 mm S45C hard-chrome rod ends in a female M8x1.25 thread with a 1/8" PT port. No magnet is fitted on this code; order the optional -S version if you later need CMSE or DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE32X20 (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 | 296.0 N |
| 0.7 MPa | 434.2 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). |
|---|---|
| 32 | Bore size in mm. |
| ×20 | 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 keeps the clamp engaged on a machined aluminium bracket whenever air pressure drops; 296 N of pull retracts the clamp arm in 20 mm for part changeover.
A divert gate on a snack-food conveyor defaults to closed when air is lost, and the 32 mm bore pulls it open at up to 500 mm/s during normal running.
A pallet stop pin stays extended to locate a housing, then air retracts it 20 mm to release the part; the female M8x1.25 rod thread takes a standard knuckle.
At 296 N pull at 0.5 MPa this bore sits in the middle of the ATP range: step down to ATP25 for lighter clamps (170.9 N) or up to ATP40 for heavier retraction work (500.3 N). Strokes beyond 25 mm are made to order, so keep the 20 mm stroke for short-retraction tasks. Because the spring returns the rod on air loss, the cylinder will not hold a mid-stroke position - design your fixture around the extended home state. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the standard face, and the -S code adds the magnet for CMSE / DMSE sensing. For new projects specify the ATE32X20, the current replacement, and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
This single acting pull cylinder gives 296 N at 0.5 MPa and 434.2 N at 0.7 MPa, both net of the return spring. Working pressure is 0.2-1.0 MPa (28-145 psi) with 0.2 MPa as the minimum to beat the spring, proof pressure is 1.5 MPa (215 psi), speed range is 50-500 mm/s, and the port is 1/8" PT with a female M8x1.25 rod thread.
The ATP series is no longer in production. Order the ATE32X20, the current ISO 21287 replacement: swap the P for an E and you get the same 32 mm bore, 20 mm stroke and force class in a short compact body. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ATP was built to a DIN-standard footprint.
