This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE12X5S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE12X5S 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 ATP12X5S
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP12X5S 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 ATE12X5S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP12X5S
Single acting pull cylinder with spring return (discontinued): the spring extends the 6 mm rod and compressed air retracts it, so the ATP12X5S sits normally extended and fails to the extended position on air loss. At the smallest bore in the family it delivers 25.9 N of pull at 0.5 MPa (42.9 N at 0.7 MPa), figures already net of the return spring, with a minimum working pressure of 0.2 MPa (28-145 psi across the 0.2-1.0 MPa range). The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke detection.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why this 12 mm bore suits slim fixtures and micro-assembly heads. In practice, plan on about 15.5 N of usable pull at 0.5 MPa, and expect it to lift roughly 1.3 kg vertically with a 2:1 margin (the raw 25.9 N equals about 2.6 kgf). A fixed TPU bumper at both ends absorbs end-of-travel shock, and the hard-anodized aluminium body with S45C hard-chrome rod keeps wear low. This model is discontinued; the current drop-in is the ATE12X5 - confirm ISO 21287 mounting dimensions before swapping, since the ATP follows the DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE12X5S (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 ATP12X5S Is Used
Lab sample probe retraction
The 25.9 N pull at 0.5 MPa withdraws a microscope or tester probe head 5 mm clear of a sample stage, and the spring pushes it back home the moment air is lost.
Micro-assembly latch release
In a compact electronics fixture, the normally extended rod holds a tiny latch open; 0.2 MPa of air is enough to retract it and seat a PCB or connector.
Vision inspection gate
With the fitted -S magnet driving a CMSE switch, a camera station confirms the 5 mm swing-away shutter is fully retracted before each image capture.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP12X5S with the ATE12X5S
At 25.9 N pull at 0.5 MPa this 12 mm bore covers tiny retraction jobs like releasing a latch or withdrawing a sensor probe; step up to the 16 mm bore (53.3 N at 0.5 MPa) if the load doubles, or downsize from a 20 mm bore (88.1 N) to save space. The 5 mm stroke is well inside the standard range for this bore, so no made-to-order stroke is needed. The female M3x0.5 rod thread takes I/Y knuckles directly, and the fitted -S magnet pairs with CMSE / DMSE switches. Because the spring only returns the rod to its extended home and never holds a mid-stroke position, do not use it to park a load. Order the ATE12X5 instead - this ATP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ATE12X5S
- ✓ 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 ATP12X5S FAQ
It is a single acting pull cylinder: the spring extends the rod and air retracts it. Pull is 25.9 N at 0.5 MPa and 42.9 N at 0.7 MPa, both net of the return spring, and at least 0.2 MPa is needed to overcome the spring. For sizing, treat about 15.5 N as usable pull at 0.5 MPa - roughly a 1.3 kg vertical lift with a 2:1 margin. Speed range is 50-500 mm/s and the M5x0.8 PT port feeds the 12 mm bore.
The S means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed or solid-state switches can be mounted to signal the retracted position; without the -S code there is no magnet. Note the ATP12X5S itself is discontinued: the current-production replacement is the ATE12X5, which matches the bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap.
