About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X100X25S
The SCT40X100X25S provides four fixed rod positions: fully retracted, 25 mm, 100 mm, and a total extended travel of 125 mm. Each of its two piston sections delivers 628 N of push force at 0.5 MPa, making it suitable for multi-stop diverting or sorting tasks. The 16 mm diameter rod and PT1/4 ports ensure a robust connection for pneumatic lines.
A built-in magnet is integrated into the piston, allowing direct mounting of CMSG, DMSG, or EMSG sensors to detect position without external brackets. The cylinder body has an A-length of 235 mm and features an adjustable air cushion of 21 mm at each end to decelerate the load smoothly.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X100X25S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X100X25S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 100 / 25 mm |
| Total travel | 125 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) | 100 mm |
| P2 (section 2) | 25 mm |
| P3 (both extended) | 125 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 SCT40X100X25S Is Used
Two-Stage Sorting Gate
Diverts packages to two different lanes using the 25 mm and 100 mm stop positions, controlled by two solenoid valves.
Multi-Depth Pressing
Applies a light touch at 25 mm stroke for alignment, then full 125 mm travel for the main pressing operation.
Sequential Part Feeding
Advances a pusher plate to a mid-point for staging, then completes the full stroke to load the next component.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X100X25S the Right Cylinder?
This 4-position tandem cylinder is ideal when an application requires two different extend strokes from a single unit, eliminating the complexity of two separate cylinders and valves. If higher force is needed, the SCT50 series provides 982 N of push per section at the same pressure. For a drop-in replacement, match the 40 mm bore, both 100 mm and 25 mm strokes, PT thread, and the -S magnet option exactly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 25 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 SCT40X100X25S FAQ
It provides four discrete mechanical stops: 0 mm (fully retracted), 25 mm, 100 mm, and 125 mm (total travel). The positions are fixed by the two different stroke lengths.
Yes, the -S suffix indicates a built-in magnet specifically designed for AirTAC's CMSG, DMSG, or EMSG series sensors to clamp directly onto the tie-rod barrel.
