About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X200X100S
The SCT80X200X100S tandem cylinder delivers four fixed rod positions—0 mm, 100 mm, 200 mm, and the full 300 mm total travel—by pressurising its two piston sections independently. Each section generates a push force of 2513 N at 0.5 MPa (4523 N at 0.9 MPa), driven by a 25 mm diameter rod through PT3/8 ports, making it a robust choice for multi-stop material handling.
A built-in magnet is integrated into the piston, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing at every stop. The 28 mm air cushion at each end decelerates the 2513 N moving mass smoothly, and the body length A(SCT) is 296 mm before adding the 300 mm total stroke.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X200X100S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø80 mm |
| Stroke 1 / Stroke 2 | 200 / 100 mm |
| Total travel | 300 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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, 28 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) | 100 mm |
| P3 (both extended) | 300 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SCT80~100 Multi-Position Tandem Cylinder SCT80X200X100S Is Used
Four-Position Diverter Gate
Direct packages to four separate conveyor lanes by stopping the gate at 0, 100, 200, or 300 mm, controlled by two 5/3 valves and sensed by the integrated magnet.
Multi-Depth Pressing Station
Achieve three pressing depths plus a retracted home position for assembling components that require different insertion forces at 100 mm, 200 mm, and 300 mm.
Staged Part Feeding
Feed parts to three distinct pick points on an assembly line by advancing the rod to 100 mm, 200 mm, or the full 300 mm position, using the CMSG sensors for precise stop confirmation.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT80X200X100S the Right Cylinder?
Choose the SCT80X200X100S when your process needs four distinct mechanical stops without the complexity of two separate cylinders and external hard stops. If your load requires more force, stepping up to the 100 mm bore provides 3927 N of push per section at 0.5 MPa; for a lighter, more compact solution, the 63 mm bore offers 1559 N. This model is a direct replacement for another AirTAC SCT80 with 200 mm and 100 mm strokes, PT ports, and a magnet.
With a 200 mm stroke on the first section, ensure the rod is guided if the load applies significant side force, as the 25 mm rod may require external support to prevent bending in cantilevered applications.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 100 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 SCT80~100 Multi-Position Tandem Cylinder SCT80X200X100S FAQ
This cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 100 mm (section 2 extended), 200 mm (section 1 extended), and 300 mm (both sections extended). The positions are fixed and selected by pressurising the appropriate cylinder ports.
Yes, if your application requires stops at 0, 100, 200, and 300 mm. The SCT integrates both strokes into one tie-rod body, saving space and eliminating the need to synchronise two actuators. Ensure the replacement matches the 200 mm and 100 mm strokes, PT3/8 ports, and the -S magnet option.
