About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X200X15S
The SCT40X200X15S is a tandem multi-position cylinder that delivers four fixed rod positions—0 mm, 15 mm, 200 mm, and the combined 215 mm stroke—from a single compact assembly. Its built-in magnet allows direct mounting of CMSG/DMSG sensors for reliable end-of-stroke or intermediate-position detection without external brackets.
Each of the two piston sections produces a push force of 628 N at 0.5 MPa, scaling to 1130 N at the maximum operating pressure of 0.9 MPa. The 40 mm bore uses a 16 mm diameter rod and PT1/4 ports, with a 21 mm adjustable air cushion in each section to manage deceleration. The body length A is 235 mm, making it a space-efficient alternative to two separate cylinders for short-long stroke sequencing.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X200X15S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X200X15S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 200 / 15 mm |
| Total travel | 215 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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) | 15 mm |
| P3 (both extended) | 215 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT40X200X15S Is Used
Two-Stage Clamp & Feed
The 15 mm stroke brings a soft clamp into contact with a delicate part, and the 200 mm stroke feeds the clamped assembly into a press or test station.
Sorting Gate with Sensor Confirmation
The built-in magnet and sensors confirm the gate is at the 15 mm divert position or the full 215 mm bypass position, preventing collisions on a conveyor.
Short Probe & Long Retract
A 15 mm extension places a measurement probe precisely on a surface, and the 200 mm retraction clears the probe fully for part changeover.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X200X15S the Right Cylinder?
Choose the SCT40X200X15S when your process needs a short 15 mm advance for a low-force locating or clamping action followed by a longer 200 mm transfer stroke, all from one air circuit. If the 628 N push force per section is marginal, stepping up to the 50 mm bore (SCT50) raises the per-section push to 982 N at 0.5 MPa; for lighter, faster moves the 32 mm bore provides 402 N. This model is a direct replacement for an existing AirTAC SCT40X200X15S with magnet, PT ports, and basic mounting—always verify both stroke sections match, as the position sequence is fixed by the two strokes. For the 200 mm section, consider external guiding or a rod-alignment coupler if the load applies a side force or the rod is fully extended.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 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 SCT40X200X15S FAQ
The four discrete rod positions are 0 mm (fully retracted), 15 mm (section 2 extended), 200 mm (section 1 extended), and 215 mm (both sections extended). Pressurise the respective section or both to reach each stop.
Yes, if your sequence requires a 15 mm and a 200 mm stroke on the same axis. The SCT40X200X15S with magnet and PT ports replaces that pair in a shorter overall package, but ensure the per-section force of 628 N at 0.5 MPa meets your load requirement for each move.
