About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X50S
The SCT32X200X50S is a double-acting tandem cylinder that provides four fixed rod positions by combining two piston sections on a common 12 mm rod. The reachable stops are 0 mm (fully retracted), 50 mm, 200 mm, and the total travel of 250 mm, selected by pressurising the sections individually or together.
Each 32 mm bore section generates 402 N of push force at 0.5 MPa (724 N at 0.9 MPa), giving predictable thrust for multi-step sequences. The built-in magnet allows CMSG or DMSG sensors to clamp directly to the tie-rod barrel for non-contact position sensing. It features a 21 mm air cushion and PT1/8 ports, with a body length A of 233 mm.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X50S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 200 / 50 mm |
| Total travel | 250 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32–100; each of the two sections has a 500 mm max standard stroke (800 mm max). Confirm against the product label before installation. Thread options: PT (standard) / G.
Stop Positions (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 200 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 250 mm |
Positions are set by pressurising section 1, section 2, or both. With equal strokes you get 3 distinct positions; with unequal strokes you get 4.
Theoretical Output Force (Ø32mm)
| 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 per actuated piston section (single-piston, same as the SC bore): push uses the full bore area, pull subtracts the rod area. Size with a safety margin.

Where the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X50S Is Used
Two-Stage Sorting Gate
The four positions (0, 50, 200, 250 mm) allow a diverter gate to retract fully, extend to a partial bypass at 50 mm, a full divert at 200 mm, or a flush-out position at 250 mm, all from one compact actuator.
Multi-Depth Pressing
Achieve two distinct pressing depths in a single cycle. The 50 mm stroke sets a light pre-form depth, while the 200 mm stroke delivers the main forming depth, with the 250 mm total travel used for part ejection.
Staggered Part Feeding
Use the 50 mm and 200 mm stops to advance parts in two increments on a conveyor escapement. The built-in magnet provides precise end-of-stroke confirmation at each position via reed sensors.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X50S the Right Cylinder?
Choose the SCT32X200X50S when an application needs a compact, repeatable four-position sequence without the complexity of two separate cylinders and external stops. The 0, 50, 200, and 250 mm positions are ideal for a two-stage feed-and-eject cycle. If higher force is needed, stepping up to the SCT40 series provides 628 N of push per section at 0.5 MPa. For drop-in replacement, match the 32 mm bore, both strokes (200 mm and 50 mm), PT port thread, and the -S magnet option. With a 200 mm stroke on section one, ensure the load is guided if side forces are present to prevent rod bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 50 mm suit your layout?
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Plumb the two sections to the correct valves for each stop.
- check Adjust end cushion screws for smooth stops.
- check Use SCT mounting accessory (FA / FB / CA / CB / LB).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X50S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 50 mm (section two extended), 200 mm (section one extended), and 250 mm (both sections extended, total travel). The positions are fixed by the two stroke lengths and cannot be infinitely adjusted.
No. Like all standard pneumatic cylinders, the SCT32X200X50S will drift or drop if pressure is lost or the valve is centered. The air cushion is for end-of-stroke deceleration, not position locking. If the load must be held at a mid-stroke position without pressure, an external rod lock or pilot-operated check valve is required.
