Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X150S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X150S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 200mm and 150mm give 4 controllable stop positions across a 350mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X150S
The SCT32X200X150S is a tandem multi-position cylinder that delivers four fixed rod positions from two strokes on a single axis: 0 mm (fully retracted), 150 mm, 200 mm, and the combined total travel of 350 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 a single actuator must reliably index between multiple hard stops.
A built-in magnet is integrated into the piston, allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing at any of the four stops. The cylinder uses a 12 mm diameter piston rod with M10x1.25 threads, PT1/8 ports, and a 21 mm adjustable air cushion in each section to manage end-of-stroke deceleration without requiring external shock absorbers.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 200 / 150 mm |
| Total travel | 350 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) | 200 mm |
| P2 (section 2) | 150 mm |
| P3 (both extended) | 350 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 SCT32X200X150S Is Used
3-Way Diverter Gate
Actuates a product gate to three distinct positions—retracted for lane A, 150 mm for lane B, and 200 mm for lane C—using a single cylinder controlled by two 5/2 valves.
Multi-Depth Pressing
Provides two controlled pressing depths (150 mm and 200 mm) plus a full-extend 350 mm position for part ejection, all from one compact tandem unit with sensor feedback at each stop.
Staged Part Feeding
Indexes a workpiece through a 150 mm pre-stage and a 200 mm final-stage position on a linear transfer line, with the built-in magnet confirming arrival at each discrete stop.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X150S the Right Cylinder?
Select this 4-position unit when a process needs to stop a load at three distinct extended points without the complexity of two separate cylinders and a coupler. The SCT approach guarantees the relative distance between the 150 mm and 200 mm stops is mechanically fixed by the piston sections, eliminating drift between two independent actuators. If higher push force is needed, stepping up to the 40 mm bore SCT40 series provides 628 N of push per section at the same 0.5 MPa pressure.
For replacement, match the bore (32 mm), both stroke lengths (200 mm and 150 mm), the PT port thread, and the built-in magnet (-S suffix). This model is a basic configuration without mounting brackets; if the application requires pivoting, a rear clevis (CA or CB) can be added to the ordering code. With a 200 mm stroke on the first section, ensure the load is guided if side forces are present to prevent rod bending on the 12 mm rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 150 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 SCT32X200X150S FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 150 mm (stroke 2 extended), 200 mm (stroke 1 extended), and 350 mm (both sections extended). These are fixed positions, not infinitely adjustable.
Yes, it is a direct functional replacement that guarantees the spatial relationship between the two strokes. Ensure the replacement matches the 32 mm bore, PT1/8 ports, and the -S magnet option for sensor compatibility.
