Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X23X23S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X23X23S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 23mm and 23mm give 3 controllable stop positions across a 46mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X23X23S
The SCT32X23X23S is a tandem multi-position cylinder that delivers three fixed rod positions: fully retracted (0 mm), extended to the first stroke (23 mm), and fully extended at the combined travel of 46 mm. 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 two distinct extended stops are needed from a single tie-rod body.
This model includes a built-in magnet (-S suffix), allowing easy attachment of CMSG, DMSG, or EMSG sensors along the barrel for non-contact position feedback. The 12 mm diameter rod and PT1/8 ports keep the footprint small, while the 21 mm adjustable air cushion at each end section helps manage end-of-stroke impact. The body length A(SCT) is 233 mm, providing a rigid base for basic foot mounting.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X23X23S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 23 / 23 mm |
| Total travel | 46 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) | 23 mm |
| P2 (both extended) | 46 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 SCT32X23X23S Is Used
Two-Way Part Diverting
Uses the 23 mm and 46 mm stops to guide small parts into two separate chutes or lanes from a single feed point, simplifying conveyor routing.
Dual-Depth Stop Gate
Provides a partial-open (23 mm) and full-open (46 mm) gate position for metering or separating components of different sizes on an assembly line.
Two-Stage Clamping
Applies a light pre-clamp at the 23 mm position before a final, full-pressure clamp at 46 mm, useful for delicate assembly processes.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X23X23S the Right Cylinder?
Choose the SCT32X23X23S when an application requires two fixed extension points without the complexity of two separate cylinders and external stops. The 32 mm bore is ideal where space is tight; if higher force is needed, stepping up to the 40 mm bore (628 N push at 0.5 MPa) is a direct path. For replacement, match the 32 mm bore, both 23 mm section strokes, PT port thread, and the -S magnet option. As both strokes are non-standard at 23 mm, this is a made-to-order configuration, so lead times may differ from standard-stroke models.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 23 + 23 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 SCT32X23X23S FAQ
It provides 3 distinct rod positions because both section strokes are equal at 23 mm. The positions are 0 mm (fully retracted), 23 mm (first section extended), and 46 mm (both sections extended, which is the total travel).
Yes. The -S suffix in the model code means it has a built-in magnet. This allows you to mount AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the cylinder's tie-rod barrel to sense each of the three discrete positions.
