About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X15S
The SCT32X100X15S is a tandem multi-position cylinder that delivers four fixed rod positions from two integrated strokes on a single axis. With a 100 mm primary section and a 15 mm secondary section, the reachable stops are 0 mm (fully retracted), 15 mm, 100 mm, and 115 mm total travel. Each piston section provides 402 N of push force at 0.5 MPa, driven through a 12 mm diameter rod.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing at each stop. The compact body has an A-length of 233 mm and uses PT1/8 ports with M10x1.25 rod-end threads. An adjustable air cushion on each section decelerates the load smoothly, making it suitable for compact sorting gates where two distinct extended positions are needed.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X15S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 100 / 15 mm |
| Total travel | 115 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) | 100 mm |
| P2 (section 2) | 15 mm |
| P3 (both extended) | 115 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 SCT32X100X15S Is Used
Two-Position Diverter Gate
Uses the 15 mm and 115 mm stops to shift a compact diverter chute between two separate lanes on a conveyor, with the 0 mm position serving as a home or third bypass lane.
Staged Part Ejection
The 100 mm stroke pushes a part clear of a die, while the 115 mm total stroke provides a secondary over-travel to ensure separation, with sensor confirmation at each stage via the built-in magnet.
Dual-Depth Labeling Press
Applies pressure at the 100 mm stop for a primary label and uses the 15 mm differential to set a lighter secondary placement depth without re-tooling the press head.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X15S the Right Cylinder?
Choose the SCT32X100X15S when your process requires a short discrete step and a longer primary stroke without installing two separate cylinders and external hard stops. The per-section push force is 402 N at 0.5 MPa; if your load needs more thrust, stepping up to the 40 mm bore provides 628 N per section. For replacement, match the 32 mm bore, both strokes of 100 mm and 15 mm, PT port thread, basic mounting, and the -S magnet option to retain sensor feedback. Since the primary stroke reaches 100 mm, ensure the rod is guided if the load applies significant side force to prevent bending the 12 mm rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 15 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 SCT32X100X15S FAQ
This tandem cylinder provides four discrete positions: 0 mm (fully retracted), 15 mm (secondary section extended), 100 mm (primary section extended), and 115 mm (both sections extended). The per-section push force is 402 N at 0.5 MPa.
Yes, it consolidates two strokes into one tie-rod body, saving space and eliminating the need to align two separate actuators. A direct replacement must match the 32 mm bore, 100 mm and 15 mm strokes, PT ports, and the -S magnet option for sensor mounting.
