This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X40S, the same code under the new prefix. 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 ACPD Double Rod Compact Cylinder ACPD16X40S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED16X40S (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting compact cylinder with a rod leaving both covers, the ACPD16X40S pushes and pulls with identical 75.4 N output at 0.5 MPa because each stroke works on the rod-side area of the 16 mm bore. The through-rod resists rotation and light side load, gives a symmetric mounting point, and lets the rear rod carry a sensor flag, while fixed TPU bumpers pad both ends of the 40 mm travel.
This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. The hard-anodized aluminium body with an S45C hard-chrome rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, ideal for tight fixtures. Note that ACPD is discontinued: the current direct is ACED16X40, and you should confirm the ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on about 45 N (roughly 4.6 kg of vertical lift with margin) of usable work at 0.5 MPa rather than the full rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X40S (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).
| ACPD | DIN compact cylinder (double-rod, discontinued). |
|---|---|
| 16 | Bore size in mm. |
| ×40 | 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 (double rod, adjustable stroke).
The 75.4 N dual-direction output ejects finished connectors or bushings off a fixture, and the rear rod can trip a CMSE switch to confirm return.
A 40 mm through-rod stroke advances sample trays on a compact benchtop analyzer where a full-length profile cylinder will not fit.
With the -S magnet fitted, DMSE switches signal extend and retract inside guarded assembly cells, using the short ISO 21287 body to save panel space.
At 75.4 N per direction this 16 mm bore suits light clamping and positioning; step down to the 12 mm bore (42.4 N) for smaller fixtures or up to the 20 mm bore (117.8 N) when parts weigh more. The piston drifts if air is lost, so add a rod lock or pilot check where a load must stay put. This unit already includes the -S magnet for CMSE / DMSE switches, and FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Order ACED16X40 as the current-production replacement.
Replacement checklist
Output is 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa, equal in both directions because the double-rod design exposes the rod-side area on every stroke; peak force is 15.4 kgf at 1.0 MPa. This model carries the optional -S magnet, so CMSE and DMSE reed or solid-state switches mount directly. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
The hard-anodized aluminium ISO 21287-style body cuts mounting length by about 50% versus an ISO 15552 profile cylinder, with M5x0.8 ports, an M4x0.7 female rod thread, fixed TPU bumpers at both ends and FA/FB flange or LB foot options. ACPD16X40S is discontinued; ACED16X40 is the current direct in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before ordering.
