About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X15S
The SCT32X15X15S is a double-acting multi-position cylinder that delivers three fixed rod positions—0 mm, 15 mm, and 30 mm—by pressurising its two tandem piston sections. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks where a standard cylinder would need external hard stops.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for end-of-stroke or mid-position confirmation. The 12 mm diameter rod and M10x1.25 rod thread provide adequate strength for small guided loads, while the 21 mm air cushion at each end helps decelerate the piston quietly.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X15S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X15S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 15 / 15 mm |
| Total travel | 30 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 15 mm |
| P2 (both extended) | 30 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 SCT32X15X15S Is Used
3-Way Diverter Gate
Positions a small flap or gate to three fixed angles—closed, partial bypass, and full divert—using the 0, 15, and 30 mm rod stops for material routing on a compact conveyor.
Two-Depth Insertion
Drives a probe or pin to a shallow 15 mm depth for one part variant and a full 30 mm depth for another, with the fully retracted position serving as the safe home state.
Multi-Stop Label Applicator
Provides three discrete tamp positions for applying labels at different heights on a package, using the integrated magnet sensors to verify each stop before firing.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X15X15S the Right Cylinder?
Choose the SCT32X15X15S when your application needs two distinct extended stops without the complexity of two separate actuators. If the 402 N push force per section is insufficient, stepping up to the 40 mm bore SCT40 delivers 628 N per section at the same pressure. For replacement, match the 32 mm bore, both 15 mm strokes, the PT port thread, and the integrated magnet; the basic mounting style means the cylinder body mounts directly via the tie-rod nuts.
As both strokes are short, rod buckling is not a concern, but ensure the load is guided if it applies any side force to the 12 mm rod.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 15 + 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 SCT32X15X15S FAQ
It provides three distinct mechanical stops: fully retracted (0 mm), the first section extended (15 mm), and both sections extended together (30 mm). Because the two strokes are equal, the 15 mm position is shared, giving three unique rod-end locations.
Yes, if your sequence requires the rod to reach 15 mm and 30 mm from a common retracted position. The SCT32X15X15S achieves this in a single tandem body, saving space and eliminating the need to synchronise two separate cylinders. Ensure the porting and the -S magnet option match your sensor requirements.
