The AirTAC SDAT double acting multi-position cylinder SDAT32X5X5 is a genuine COMPACT duplex cylinder (Ø32mm bore) built from two stacked piston sections of 0 mm and 0 mm. Switching the two chambers gives fixed rod stops at 0, 0 and 0 mm — three repeatable positions from a single actuator.
The SDAT32X5X5 is a double-acting compact duplex cylinder that reaches three repeatable stops from a single actuator: fully retracted (0 mm), 5 mm out, and 10 mm out. Its two stacked piston sections are selected by air chambers, so a fixture gets mechanical intermediate positions without external stop blocks or a second cylinder.
Thrust comes from one piston only, matching a plain SDA of 32 mm bore: 402.1 N push and 345.6 N pull at 0.5 MPa. The duplex layout adds positions, never extra force. End-of-stroke damping is a fixed NBR bumper, and the 12 mm rod carries a female M6x1.0 thread with PT1/8 ports.

| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper |
| Stroke rule | Stroke 1 + Stroke 2 ≤ standard max |
Stroke 1 + Stroke 2 must not exceed the standard stroke maximum for the bore. Confirm the exact stop sequence against the AirTAC SDAT datasheet before wiring the valves.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force is set by the single piston area (same as an SDA of this bore) — the duplex design adds positions, not thrust. Actual usable force is lower than theoretical.

On a small parts dial plate, the rod stops at 5 mm for partial ejection of short pieces and 10 mm for full knock-off, clearing stuck parts without changing tooling.
In a compact feeder magazine, the 10 mm total travel lets a gate present parts at two check heights, sized well within the 402.1 N push capability at 0.5 MPa.
A electronics test nest uses the 0/5/10 mm sequence to clamp, pre-align, then seat a PCB carrier, all from one cylinder with fixed NBR bumper ends.
At 0.5 MPa this bore pushes 402.1 N. If your load needs less, the 25 mm bore version gives 245.4 N; if you need more, step up to 40 mm for 628.3 N. Confirm bore, S1=5, S2=5, PT1/8 port, rod thread, and whether the -S magnet option is required.
Both sections must be valved, so budget two solenoid lines to hit all three stops. Note that positions are held only while pressure is live - if air is lost the stops let go, so add an external lock for load holding. Speed range is 30-500 mm/s.
Quick checklist
Stops are at 0, 5, and 10 mm. Force equals a single 32 mm SDA piston: 402.1 N push and 345.6 N pull at 0.5 MPa, 563.0 N push at 0.7 MPa, with a maximum push near 82 kgf at 1.0 MPa. The duplex build does not double thrust.
Air is routed to different combinations of the two piston chambers. One chamber pairing holds the rod at 5 mm, another drives it to 10 mm, and exhausting both returns it to 0. Each stop is a mechanical position, so two solenoid valves are needed in the circuit.
