About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X200X100S
The SCT63X200X100S is a double-acting multi-position cylinder that delivers four fixed rod positions from two independent piston sections on a common rod line. With strokes of 200 mm and 100 mm, the reachable stops are 0 mm (fully retracted), 100 mm, 200 mm, and the total travel of 300 mm, selected by pressurising either or both sections.
Each 63 mm bore section generates 1559 N of push force at 0.5 MPa, rising to 2805 N at the maximum operating pressure of 0.9 MPa. The cylinder features a 20 mm diameter rod with an M16x1.5 thread, PT1/4 ports, and a 28 mm adjustable air cushion. The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors for non-contact position feedback.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X200X100S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | ร63 mm |
| Stroke 1 / Stroke 2 | 200 / 100 mm |
| Total travel | 300 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16ร1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 โ 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 โ 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32โ100; 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) | 100 mm |
| P3 (both extended) | 300 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 (ร63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | โ |
| Max (@1.0 MPa) | 318 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 SCT63X200X100S Is Used
Two-Stage Sorting Gate
Uses the 100 mm and 200 mm positions to divert packages to three separate conveyor lanes from a single actuator, simplifying the sorting mechanism.
Multi-Depth Pressing
Provides three controlled pressing depths (100, 200, and 300 mm) for forming or assembly operations that require different insertion or compression levels in one cycle.
Sequential Clamping
First extends to 100 mm to clamp a thin workpiece, then to 200 mm for a thicker variant, or to the full 300 mm for the thickest part, all with a single cylinder.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X200X100S the Right Cylinder?
Choose the SCT63X200X100S when your application requires four distinct mechanical stops without the complexity of servo control or the space of two separate cylinders. The 200 mm and 100 mm stroke combination is ideal for a two-step advance with an intermediate position. If higher force is needed, stepping up to the 80 mm bore provides 2513 N of push per section at 0.5 MPa. For a direct replacement, match the 63 mm bore, both the 200 mm and 100 mm strokes, PT port thread, and the integrated magnet (-S). Note that with a 200 mm section stroke, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- โ Need 4 repeatable stops?
- โ Section strokes 200 + 100 mm suit your layout?
- โ Required force at your working pressure
- โ Port/thread type (PT/NPT/G)
- โ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 โ 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 SCT63X200X100S FAQ
It has four distinct mechanical stop positions: 0 mm (fully retracted), 100 mm, 200 mm, and the total combined travel of 300 mm. These are achieved by pressurising the first section, the second section, or both simultaneously.
Yes, if your sequence requires fixed stops at 100, 200, and 300 mm. The SCT provides these three extended positions from a single tie-rod body, saving space and eliminating the need to synchronise two separate actuators. Ensure the per-section force of 1559 N at 0.5 MPa meets your load requirements.
