About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X65X65S
The SCT50X65X65S is a double-acting multi-position tandem cylinder that provides three fixed rod positions: fully retracted (0 mm), an intermediate stop at 65 mm, and full extension at 130 mm. Each 50 mm bore section delivers 982 N of push force at 0.5 MPa, driven by a 20 mm diameter piston rod and equipped with a 21 mm adjustable air cushion for smooth end-of-stroke deceleration.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position sensing. With a body length of 243 mm, it is a compact solution for sorting or diverting tasks that require a precise mid-stroke location without the complexity of two separate cylinders.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X65X65S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X65X65S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø50 mm |
| Stroke 1 / Stroke 2 | 65 / 65 mm |
| Total travel | 130 mm |
| Stop positions | 3 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 65 mm |
| P2 (both extended) | 130 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCT50X65X65S Is Used
3-Position Diverter Gate
Uses the three distinct stops (0, 65, 130 mm) to route packages or parts down two different conveyor lanes from a single in-feed point, simplifying line design.
Two-Depth Pressing Station
Provides a retracted safe position, a partial insertion depth at 65 mm for pre-forming, and a final press depth at 130 mm, all from one compact tandem unit.
Staged Part Feeding
Advances components in two controlled steps. The built-in magnet confirms the cylinder has reached the 65 mm mid-point before the control system commands the final 130 mm extension.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT50X65X65S the Right Cylinder?
Choose the SCT when your application needs a defined intermediate stop position without the cost and plumbing of two individual actuators. For this 65 mm per section stroke, the 50 mm bore is a strong starting point; if your load requires less force, stepping down to a 40 mm bore provides 628 N of push per section at 0.5 MPa. For a direct replacement, match the 50 mm bore, both 65 mm strokes, PT port thread, basic mounting, and the -S magnet option to ensure sensor compatibility.
As the total travel reaches 130 mm, ensure the load is guided if there is any off-axis weight to prevent rod bending. The SCT is a tie-rod design and is not interchangeable with ISO 15552 profiles.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 65 + 65 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 SCT50X65X65S FAQ
It provides 3 discrete mechanical stops: 0 mm (fully retracted), 65 mm (first section extended), and 130 mm (both sections extended). Because both strokes are equal at 65 mm, the total travel is 130 mm.
Yes. The 'S' suffix signifies a built-in magnet along the piston. You can directly clamp AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors onto the cylinder's tie-rods to detect the 65 mm and 130 mm positions.
