The AirTAC SDAW Dual-Axis Compound Multi-Position Cylinder SDAW32X45X50SB is a genuine COMPACT duplex-end cylinder (Ø32mm bore) with a 0 mm and a 0 mm section combined at the rod end. Switching the two chambers parks the rod at 0, 0 and 0 mm — three repeatable stops without an external stopper.
The SDAW32X45X50SB is a double-acting compact duplex-end multi-position cylinder. The rod-end section sits behind the working chamber, so the single rod stops at three repeatable positions: 0, 45 and 95 mm. Which stop is reached depends on how the two chambers are pressurised, giving fixed indexing without a second cylinder.
Force is set by one piston area only: this 32 mm bore delivers 402.1 N push at 0.5 MPa, the same as a single SDA of the same size - the duplex-end layout adds positions, not thrust. The body carries standard sensor grooves, and since this model has the S magnet option, AirTAC reed or electronic switches can be mounted directly to confirm each stop. Travel speed spans 30-500 mm/s and a fixed NBR bumper absorbs end shock.

Force is set by the single piston area (same as an SDA of this bore) — the duplex-end design adds positions, not thrust. Actual usable force is lower than theoretical.

A sorting line needs trays pushed into three different lanes. Stops at 0, 45 and 95 mm from one rod-end duplex actuator replace two cylinders in the short bay, with 402.1 N push at 0.5 MPa moving loaded trays.
A packaging conveyor uses a gate that must park flush, half-raised or fully raised depending on carton size. The 45 mm and 95 mm stops match the two gate heights, and the S magnet lets a reed or electronic switch verify each gate state.
A machining fixture plate is lifted to three preset heights for different part families. The male M10x1.25 rod thread takes the lift bracket directly, and the fixed NBR bumper quiets each stop at 30-500 mm/s travel.
Check thrust before ordering. Bore 25 gives 245.4 N push at 0.5 MPa; bore 40 gives 628.3 N - pick the bore whose single-piston force covers your load with margin, because the duplex-end never doubles output. Total travel here is 95 mm, inside the 120 mm standard-stroke limit for bore 32.
Plumbing matters: two solenoid lines are required to reach all three positions, and with no air applied the rod will not hold its stop or the load - use an external locking device if load holding without pressure is needed. Choose SDAW when the extra section must sit at the rod end for a shorter body; choose SDAT if a stacked layout suits the machine better. Confirm bore 32, S1 = 45, S2 = 50, PT1/8 port, male rod thread M10x1.25 (B option) and the S magnet code on your order.
Quick checklist
Stops are at 0 mm, 45 mm and 95 mm (S1 + S2), selected by the two chambers. Force comes from one piston area, not doubled: 402.1 N push at 0.5 MPa, 345.6 N pull at 0.5 MPa, 563.0 N push at 0.7 MPa, and up to 82 kgf push at 1.0 MPa for the 32 mm bore.
In the SDAW the second piston section is built at the rod end, while the SDAT stacks it behind the first section - both give multi-position stops with single-piston force. The body sensor grooves only work with the -S magnet code, which this model has; then AirTAC reed or electronic switches confirm each stop.
