About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X175S
The SCT32X15X175S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions: 0 mm (fully retracted), 15 mm, 175 mm, and the combined total travel of 190 mm. Each of its two 32 mm bore sections generates 402 N of push force at 0.5 MPa, making it suitable for light-duty sorting or diverting tasks where two distinct extended stops are needed alongside the home position.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position confirmation at each stop. The 12 mm diameter rod and PT1/8 ports keep the package compact, while the 21 mm adjustable air cushion at each end helps manage end-of-stroke impact during the 30-800 mm/s speed range.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X175S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 15 / 175 mm |
| Total travel | 190 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) | 15 mm |
| P2 (section 2) | 175 mm |
| P3 (both extended) | 190 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 SCT32X15X175S Is Used
Two-Way Part Diverting
Use the 15 mm stop for a reject gate and the 175 mm stop for the main pass-through lane, directing parts on a conveyor with a single actuator.
Multi-Depth Stopping
Stop a pallet or carrier at a 15 mm pre-stop for scanning and then advance to the 175 mm position for a full pick-and-place operation.
Dual-Position Clamping
Clamp a thin workpiece at the 15 mm stroke and a thicker variant at the 175 mm stroke without changing tooling, using sensor feedback from the built-in magnet.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X175S the Right Cylinder?
Choose the SCT32X15X175S when your process requires two different extended positions from a single compact actuator, eliminating the complexity of two separate cylinders and external hard stops. The 15 mm and 175 mm strokes give you a short precise advance and a longer feed motion from one unit. If you need more force per section, stepping up to the 40 mm bore SCT40 provides 628 N of push at 0.5 MPa. For drop-in replacement, match the 32 mm bore, both strokes (15 mm and 175 mm), PT port thread, and the -S magnet option. Since the 175 mm section stroke is under 300 mm, rod side-loading is minimal in standard horizontal mounting.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 15 + 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 SCT32X15X175S FAQ
This tandem cylinder provides 4 discrete mechanical stops: 0 mm (fully retracted), 15 mm (first section extended), 175 mm (second section extended), and 190 mm (both sections extended). The stops are fixed by the two stroke lengths and are not infinitely adjustable.
Yes, the -S suffix indicates a built-in magnet, so you can directly mount CMSG reed switches or DMSG/EMSG solid-state sensors on the cylinder's tie-rod barrel to detect each of the four positions.
