The AirTAC SDAT double acting multi-position cylinder SDAT32X5X10SB 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.
This SDAT32X5X10SB is a double-acting compact duplex cylinder built for short multi-position moves. The rod pauses at 0 mm, 5 mm and 15 mm because two piston sections share the compact riveted body. Selecting which chamber receives air snaps the rod to the chosen mechanical stop, doing the job of two slim cylinders in the space of about one.
Force scales with a single piston of the 32 mm bore: 402.1 N push at 0.5 MPa. Duplex stacking changes the number of dwell points, never the thrust. Even with both sections stacked the body stays short, which suits tight machine envelopes where two separate cylinders would not fit. A fixed NBR bumper cushions end-of-travel shock and offers no adjustment. The supplied magnet pairs with AirTAC reed or electronic switches to report every stop.

| 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.

| 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.

A 5 mm pre-clamp guards delicate electronics housings, then 15 mm adds full clamping force. 402.1 N push at 0.5 MPa is ample for small fixture work on the 12 mm rod.
Short 5 and 15 mm kicks nudge packs onto a checkweigher belt by preset offsets. Two valves toggle between stops, replacing an added stopper cam at the discharge.
Lab automation raises a microscope slide stage to 5 mm or 15 mm sampling heights. The compact stacked body fits where two cylinders would crowd the frame, and reed switches log each height.
Sizing check at 0.5 MPa push: 245.4 N from a 25 mm bore may be too little, while 628.3 N from a 40 mm bore may be overkill. The 32 mm bore at 402.1 N push sits between them, so verify load plus friction before committing. Two solenoid valves are required to reach 0, 5 and 15 mm. Stops are pressure-dependent - if air drops or valves sit mid-position the rod is not held, so add an external brake for unpowered load holding.
Confirm the spec set: bore 32, S1 5, S2 10, PT1/8 ports, -S magnet option, male rod thread M10x1.25 (the B suffix). Speed window is 30-500 mm/s.
Quick checklist
Positions are 0, 5 and 15 mm (S1 5 plus S2 10). Thrust is that of one 32 mm piston - duplex does not double it: 402.1 N push, 345.6 N pull at 0.5 MPa, 563.0 N push at 0.7 MPa, and a maximum 82 kgf push at 1.0 MPa. Proof pressure is 1.5 MPa and speed runs 30-500 mm/s.
The B suffix specifies a male M10x1.25 rod-end thread instead of the standard female M6x1.0. The -S magnet built into the piston works with AirTAC reed or electronic (solid-state) switches held in the body grooves, letting you wire one switch per stop position.
