About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X110X10S
The SCT40X110X10S is a double-acting multi-position cylinder that provides four distinct rod positions from its two piston sections: 0 mm, 10 mm, 110 mm, and the total travel of 120 mm. Each section delivers a push force of 628 N at 0.5 MPa, making it a capable actuator for tasks requiring a short, precise first stop and a longer second advance.
This genuine AirTAC unit features a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors on its tie-rod barrel for reliable end-of-stroke or mid-position detection. The 40 mm bore model uses a 16 mm diameter rod with M12x1.25 threads and PT1/4 ports, with a body length of 235 mm plus the combined stroke.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X110X10S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X110X10S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 110 / 10 mm |
| Total travel | 120 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) | 110 mm |
| P2 (section 2) | 10 mm |
| P3 (both extended) | 120 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 SCT40X110X10S Is Used
Two-Stage Clamping
Uses the 10 mm stroke for a low-force initial contact, then the 110 mm stroke applies full pressure, preventing damage to delicate parts.
Part Sorting Gate
The four positions divert items to separate lanes, with sensors on the magnet-equipped barrel confirming each stop for the controller.
Dual-Depth Pressing
Achieves two different insertion or forming depths in one cycle, with the 10 mm stop acting as a precise gauging position before the full 120 mm travel.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X110X10S the Right Cylinder?
Choosing the SCT40X110X10S over two separate cylinders or an SC with external stops simplifies the circuit to a single actuator with fixed, repeatable stopping points. If your application needs more force, the 50 mm bore SCT provides 982 N of push per section at the same pressure. For a direct replacement, match the 40 mm bore, both the 110 mm and 10 mm strokes, the PT port thread, and the integrated magnet; the basic mount offers flexibility for custom bracketry.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 110 + 10 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 SCT40X110X10S FAQ
The rod stops at 0 mm (fully retracted), 10 mm (first section extended), 110 mm (second section extended), and 120 mm (both sections extended). The strokes are unequal, giving four distinct positions.
Yes, the built-in magnet designated by the 'S' in the model code makes it compatible with AirTAC's CMSG, DMSG, and EMSG series sensors, which clamp directly onto the cylinder's tie-rod barrel.
