This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE12X5 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE12X5 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 ATP12X5
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP12X5 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 ATE12X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP12X5
A single acting compact pull cylinder, the ATP12X5 uses an internal spring to extend the rod and compressed air to retract it, so the 12 mm bore delivers a net pull of 25.9 N at 0.5 MPa (42.9 N at 0.7 MPa) after the spring is subtracted. It needs at least 0.2 MPa of air to overcome the spring, runs on 40 um filtered air at 0.2-1.0 MPa (28-145 psi), and moves at 50-500 mm/s. This model is discontinued; the current-production replacement is the ATE12X5 in the same bore, stroke and force class.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits micro jigs and sensor stations where every millimetre counts. The hard-anodized aluminium body carries an S45C hard-chrome rod with a female M3x0.5 thread, and fixed TPU bumpers sit at both ends. Plan on about 15 N of usable pull at 0.5 MPa, which lifts roughly 1.5 kg vertically with a 2:1 margin. No magnet is fitted on this code; order the optional -S version to enable CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE12X5 (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 ATP12X5 Is Used
Micro part ejection from vision-inspection nests
The spring-extended rod holds a tiny ejector pin forward at rest; 25.9 N of air pull at 0.5 MPa retracts it 5 mm so the camera gets a clear view of the part.
Spring-forward gate on a small rotary indexing table
On air loss the spring returns the gate to its extended home position, a fail-safe posture for clearing jammed components in a compact 5 mm travel window.
Sample probe retraction in a laboratory dispenser
The 1.5 kg-class vertical pull (about 15 N usable) is enough to withdraw a light sampling probe, and the short body fits inside the instrument housing.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP12X5 with the ATE12X5
At 25.9 N of net pull at 0.5 MPa this 12 mm bore is the smallest in the family; step up to the 16 mm bore (53.3 N) if your mechanism needs roughly twice the retraction force, or downsize from a 16 if 25.9 N already covers it. The 5 mm stroke is well 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 brackets to your fixture, add the -S code only if you need CMSE / DMSE position switches, and confirm the ATE12X5 ISO 21287 mounting dimensions before swapping from this discontinued unit.
Replacement checklist
- ✓ Current-production ACE → ATE12X5
- ✓ 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 ATP12X5 FAQ
Net of the return spring, the 12 mm bore pulls 25.9 N at 0.5 MPa and 42.9 N at 0.7 MPa; 0.2 MPa minimum air is needed to beat the spring. Operating range is 0.2-1.0 MPa (28-145 psi), proof 1.5 MPa (215 psi), temperature -20 to +70 C, speed 50-500 mm/s, stroke 5 mm with a 6 mm rod on a female M3x0.5 thread and an M5x0.8 PT port. The model is discontinued; the ATE12X5 is the current drop-in.
The spring pushes the rod to its extended home position and holds it there, so the cylinder fails to extended; it does not hold a mid-stroke position and the fixed TPU bumpers only decelerate the rod at each end of travel. If you need position sensing, order the optional -S magnet version, which accepts CMSE / DMSE switches - this base code carries no magnet.
