About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X65S
The SCT32X100X65S is a double-acting multi-position tandem cylinder that delivers four discrete rod positions: 0 mm, 100 mm, 65 mm, and the full 165 mm total travel. By pressurising the two piston sections independently or together, it replaces complex multi-actuator setups with a single tie-rod unit. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, driven through a 12 mm diameter rod with M10x1.25 threads.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for non-contact position confirmation at each stop. The compact body has an A-length of 233 mm, with 21 mm of adjustable air cushion in each section to decelerate the load smoothly. Operating on standard PT1/8 ports, it suits filtered air systems from 0.15 to 1.0 MPa and ambient temperatures from -20 to +70 °C with its TPU seals.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X65S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 100 / 65 mm |
| Total travel | 165 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) | 65 mm |
| P3 (both extended) | 165 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 SCT32X100X65S Is Used
3-Way Diverter Gate
Use the four discrete stops to route packages to three different conveyor lanes. The 100 mm stroke shifts the gate to a middle lane, while the 65 mm stroke provides a precise offset for a third position.
Two-Depth Pressing Station
Achieve a shallow pre-press at 65 mm and a full-depth press at 165 mm total travel. The integrated magnet sensors confirm each depth before the next cycle, improving part consistency.
Multi-Stop Component Feed
Advance a workpiece carrier to a 100 mm inspection point, then a 65 mm offset for a secondary drilling operation. The 12 mm rod and tie-rod construction maintain alignment across all four positions.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X65S the Right Cylinder?
Choose the SCT when your application requires two fixed intermediate positions without the cost and alignment complexity of two separate cylinders and external hard stops. The 32 mm bore is ideal for light sorting or diverting tasks; if you need more force, stepping up to the 40 mm bore provides 628 N of push per section at the same 0.5 MPa pressure. For replacement, match the bore, both strokes (100 mm and 65 mm), the PT port thread, and the built-in magnet (-S suffix) to ensure sensor compatibility. This basic mounting configuration requires the machine frame to support the cylinder body directly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 65 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 SCT32X100X65S FAQ
This tandem cylinder provides four distinct rod positions: fully retracted (0 mm), the first section extended (100 mm), the second section extended (65 mm), and both sections extended for the total travel of 165 mm. The unequal strokes create four unique stopping points.
Yes, the -S suffix indicates a built-in magnetic band on the piston, making it compatible with AirTAC CMSG, DMSG, and EMSG series reed and solid-state sensors. These sensors clamp directly onto the cylinder barrel to detect each of the four discrete positions.
