About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X60S
The SCT32X30X60S is a tandem multi-position cylinder providing four fixed rod positions at 0 mm, 30 mm, 60 mm, and the total travel of 90 mm. Each 32 mm bore section delivers 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sorting or diverting tasks where multiple end-points are needed from a single pneumatic unit.
A built-in magnet allows CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke sensing at any of the four positions. The cylinder uses a 12 mm diameter rod, PT1/8 ports, and an M10x1.25 rod thread, with a 21 mm adjustable air cushion in each section to manage deceleration smoothly.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X60S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X60S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 30 / 60 mm |
| Total travel | 90 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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) | 30 mm |
| P2 (section 2) | 60 mm |
| P3 (both extended) | 90 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32X30X60S Is Used
Multi-Chute Diverter
Directs small packages to one of three lanes by pressurising section one, section two, or both, using the four discrete rod positions to align with different conveyor chutes.
Two-Depth Pressing
Provides two distinct pressing depths (30 mm and 90 mm) in a light assembly fixture, with a safe retracted home position and a partial-advance stop for delicate component insertion.
Staged Part Ejection
Ejects parts from a nest in two stages: a 30 mm push to break stiction, followed by a full 90 mm stroke to clear the part, all controlled by sequencing pressure to the tandem sections.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X30X60S the Right Cylinder?
Choose this 4-position SCT model when your process needs a single actuator to stop at 30 mm, 60 mm, and 90 mm, replacing two separate cylinders and external hard stops. If the 402 N push force per section is marginal, stepping up to a 40 mm bore provides 628 N per section at the same pressure. For replacement, match the 32 mm bore, both strokes (30 mm and 60 mm), PT port thread, and the integrated magnet (-S suffix).
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 30 + 60 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 SCT32X30X60S FAQ
This tandem cylinder reaches four discrete positions: fully retracted (0 mm), first section extended (30 mm), second section extended (60 mm), and both sections extended for the total travel of 90 mm. It does not provide infinitely variable positioning.
The -S suffix indicates a magnet is embedded in the piston, allowing CMSG, DMSG, or EMSG solid-state sensors to mount externally on the cylinder barrel. This provides non-contact position sensing at any of the four stops without additional brackets.
