About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X175S
The SCT32X200X175S is a tie-rod multi-position cylinder that delivers four fixed rod positions from two independent piston sections on a common 12 mm rod. With strokes of 200 mm and 175 mm, the reachable stops are 0 mm (fully retracted), 175 mm, 200 mm, and the total travel of 375 mm when both sections are pressurised. Each section provides 402 N of push force at 0.5 MPa, rising to 724 N at the 0.9 MPa maximum operating pressure.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the tie-rod barrel for end-of-stroke or mid-position confirmation. The PT1/8 ports and 21 mm adjustable air cushion on each section give you fine control over deceleration. The body length A(SCT) is 233 mm, making it a compact solution for multi-stop sorting or diverting tasks where sensor feedback is essential.

| Total travel | 375 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) | 175 mm |
| P3 (both extended) | 375 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 SCT32X200X175S Is Used
Multi-Gate Diverter
Use the four discrete positions (0, 175, 200, 375 mm) to direct parts into three separate lanes on a conveyor, with sensor confirmation at each stop via the built-in magnet.
Two-Depth Pressing
Achieve two distinct pressing depths in a single cycle. The 175 mm stroke sets the first depth, and the 200 mm stroke sets the second, deeper position, with the total 375 mm travel for part ejection.
Staged Part Transfer
Pick a component at 0 mm, advance it 175 mm to a vision inspection station, then extend the second section to 200 mm for placement, using the sensor magnet to verify each transfer step.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X175S the Right Cylinder?
Choose the SCT32X200X175S when your application requires four discrete mechanical stops without the complexity of servo drives or multiple single-stroke cylinders and external hard stops. The 200 mm and 175 mm stroke combination is ideal for two-depth insertion or a three-gate diverter. If you need more force per section, step up to the 40 mm bore SCT40, which delivers 628 N push at 0.5 MPa. For replacement, match the bore (32), both strokes (200 and 175), the -S magnet, and the PT port thread. Note that with a 200 mm stroke section, ensure the rod is adequately guided if significant side loads are present to prevent bending of the 12 mm rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 175 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 SCT32X200X175S FAQ
This cylinder provides 4 distinct mechanical stop positions because the two section strokes are different (200 mm and 175 mm). The exact positions are 0 mm (fully retracted), 175 mm, 200 mm, and the combined total travel of 375 mm. You select a position by pressurising the first section, the second section, or both simultaneously.
Yes, in many cases it can. It replaces two individual SC32 cylinders and their mounting hardware with a single tandem unit that provides four fixed stops. To be a direct functional replacement, ensure the replacement SCT matches the 32 mm bore, both the 200 mm and 175 mm strokes, the -S magnet for sensors, and the PT1/8 port thread. The per-section force (402 N push at 0.5 MPa) is identical to a standard SC32.
