About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X200S
The SCT32X300X200S is a tandem multi-position pneumatic cylinder that provides four discrete rod stops: 0 mm (fully retracted), 200 mm, 300 mm, and the full 500 mm total travel when both sections are pressurized. Operating at 0.5 MPa, each piston section delivers 402 N of push force and 345 N on the pull stroke, making it suitable for light sorting and diverting tasks where multiple fixed positions are required without complex servo controls.
This model features a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, enabling reliable end-of-stroke and intermediate position detection. It is a tie-rod design with a 12 mm diameter piston rod and PT1/8 port threads. The adjustable air cushion at each end is 21 mm long, providing smooth deceleration across the 30-800 mm/s speed range.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X200S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 300 / 200 mm |
| Total travel | 500 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) | 300 mm |
| P2 (section 2) | 200 mm |
| P3 (both extended) | 500 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 SCT32X300X200S Is Used
Two-Stage Part Diverting
Actuates a diverter gate to three distinct positions—neutral, first divert path, and second divert path—using the 200 mm and 300 mm strokes to route packages on a conveyor line.
Sequential Stop Feeding
Controls a feed mechanism with an intermediate pause. The rod extends 200 mm to a pre-feed position, pauses, then extends to the full 500 mm to complete the material advance.
Multi-Depth Light Pressing
Provides two controlled pressing depths in a light assembly fixture. The 200 mm stroke sets a shallow insertion depth, while the 300 mm stroke completes a deeper seating operation.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X300X200S the Right Cylinder?
Select the SCT32X300X200S when your application requires four precise, repeatable stop positions from a single compact actuator, eliminating the cost and complexity of two separate cylinders and external hard stops. The 300 mm and 200 mm strokes provide asymmetric positioning ideal for two-step feeding or ejection sequences. For higher thrust, consider stepping up to the 40 mm bore SCT, which provides 628 N of push force per section at 0.5 MPa.
As a direct replacement, match an SCT with a 32 mm bore, 300 mm first stroke, 200 mm second stroke, PT thread, and the -S magnet option. For strokes of this length, ensure the rod is adequately guided if side loads are present, as the 12 mm rod is susceptible to bending under off-axis forces.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 300 + 200 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 SCT32X300X200S FAQ
This model provides four distinct mechanical stop positions: 0 mm (fully retracted), 200 mm (second section extended), 300 mm (first section extended), and 500 mm (both sections extended for total travel).
No, a standard single-rod SC cylinder only provides two positions (fully retracted and fully extended). To replicate the four fixed stops of this SCT, you would need a tandem SCT model with the exact same bore (32 mm), both strokes (300 mm and 200 mm), port thread, and the -S magnet option for sensor compatibility.
