About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X15X100S
The AirTAC SCT100X15X100S is a tandem multi-position cylinder that delivers four fixed rod positions—0 mm, 15 mm, 100 mm, and 115 mm total travel—from a single compact unit. Its 100 mm bore generates a substantial 3927 N of push force per actuated section at 0.5 MPa, making it ideal for heavy-duty staging or sorting tasks where two distinct intermediate stops are required.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for reliable end-of-stroke or mid-position detection. The 25 mm diameter rod and 29 mm adjustable air cushion at each end help manage kinetic energy during high-cycle operation, while the PT1/2 port threads ensure straightforward pneumatic connections.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X15X100S Technical Specifications
| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X15X100S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 15 / 100 mm |
| Total travel | 115 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/2 |
| 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, 29 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) | 15 mm |
| P2 (section 2) | 100 mm |
| P3 (both extended) | 115 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCT100X15X100S Is Used
Two-Stage Clamping
Uses the 15 mm stroke for a rapid low-force approach and the 100 mm stroke for full-power clamping, protecting delicate parts from impact damage.
Dual-Position Diverter Gate
Directs packages to one of two lanes by stopping at the 15 mm or 115 mm position, with sensor confirmation via the integrated magnet.
Sequential Press Operations
Executes a light 15 mm pre-press followed by a 100 mm deep-draw stroke in progressive die tooling, all from a single cylinder body.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X15X100S the Right Cylinder?
Choose the SCT100X15X100S when your process needs a short 15 mm advance and a longer 100 mm secondary stroke without the complexity of two separate actuators and external hard stops. For lighter loads, stepping down to an 80 mm bore reduces the per-section push force to 2513 N at 0.5 MPa, which may be sufficient and can lower air consumption. If you are replacing an existing unit, match the 100 mm bore, both the 15 mm and 100 mm strokes, PT port threads, and the built-in magnet suffix (-S) to ensure sensor compatibility.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 15 + 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 SCT100X15X100S FAQ
This tandem cylinder provides four discrete positions: fully retracted (0 mm), first section extended (15 mm), second section extended (100 mm), and both sections extended (115 mm total travel).
Yes, the -S suffix indicates a built-in magnet, making it fully compatible with AirTAC CMSG, DMSG, and EMSG series reed and solid-state sensors that clamp directly onto the cylinder's tie-rods.
