This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE40X10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE40X10S 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 ATP40X10S is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø40mm bore and 10mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE40X10S (ISO 21287 ACE), in the same bore, stroke and force class.
A single acting pull cylinder with spring return (discontinued), the ATP40X10S keeps its 12 mm rod retracted by air and lets the internal spring extend it to the home position whenever pressure drops. At 0.5 MPa it delivers a net pull of 500.3 N (729 N at 0.7 MPa), already discounted for the spring, so what you see is what reaches the work. The 40 mm bore takes a 1/8" port and the rod end carries a female M8x1.25 thread.
The short ISO 21287-style body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight clamping nests and guarded stations. Because this unit carries the optional -S magnet, CMSE or DMSE reed and solid-state switches can be bolted on for end-of-stroke signalling. Plan on about 300 N of usable work at 0.5 MPa, or roughly 25 kg of vertical lift with a 2:1 margin. Note this model is discontinued; the current-production drop-in is the ATE40X10, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE40X10S (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 | 500.3 N |
| 0.7 MPa | 729.0 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). |
|---|---|
| 40 | Bore size in mm. |
| ×10 | 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).
On a CNC fixture the spring holds the clamp engaged by default; 500.3 N of air pull at 0.5 MPa releases the part only while pressure is applied, a fail-safe pattern for power-off events.
A 10 mm pull stroke is ideal for retracting a vacuum cup or gripper jaw on small electronics assemblies, where the 25 kg vertical-lift equivalent covers lightweight carriers.
With the -S magnet fitted, CMSE or DMSE switches confirm the rod is fully extended before a packaging machine interlock allows the next cycle.
Size by pull, not push: this 40 mm bore nets 500.3 N at 0.5 MPa. If your load needs less, the 32 mm bore (296 N at 0.5 MPa) saves space; if it needs more, step up to the 50 mm bore at 775 N. The spring returns the rod to extended on air loss and will not hold a mid-stroke position, so add external locators if you need to park a load. Match FA/FB flange, LB foot or CA/CB clevis brackets to your fixture, and keep the -S magnet if you run CMSE / DMSE switches. Order the ATE40X10 as the current replacement for this discontinued model.
Replacement checklist
At 0.5 MPa the net pull is 500.3 N and at 0.7 MPa it is 729 N, both already reduced by the return spring, so no further derating is needed. Air retracts the rod and the spring extends it; at least 0.2 MPa (28-145 psi operating band, 0.2-1.0 MPa) is required to overcome the spring. Speed range is 50-500 mm/s and the rod end is a female M8x1.25 thread on a 12 mm rod.
No, the ATP family is discontinued. The current-production successor is the ATE40X10, which swaps the P for an E and matches the same 40 mm bore, 10 mm stroke and force class in a short ISO 21287 body with FA/FB flange, LB foot and CA/CB clevis mounting options. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, and re-order the -S magnet code if you rely on CMSE / DMSE switch signalling.
