About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X50S
The SCT32X100X50S is a double-acting multi-position cylinder that delivers four fixed rod positions—0 mm, 50 mm, 100 mm, and 150 mm total travel—from two independently controlled piston sections on a single rod line. With a 12 mm rod and M10x1.25 rod thread, each section generates 402 N of push force at 0.5 MPa, making it a compact solution for light-duty sequencing tasks.
A built-in magnet (the -S suffix) allows CMSG, DMSG, or EMSG sensors to mount directly on the tie-rod barrel for position feedback at every stop. The cylinder body has a length A of 233 mm and uses PT1/8 ports, with an adjustable air cushion of 21 mm on each section to decelerate the load smoothly.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X50S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X50S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 100 / 50 mm |
| Total travel | 150 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) | 100 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 150 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 SCT32X100X50S Is Used
Two-Stage Diverter Gate
Uses the 50 mm stroke to clear a main lane and the 100 mm stroke to reach a secondary sorting lane, giving four gate positions for routing packages.
Multi-Depth Label Applicator
The 0, 50, 100, and 150 mm stops allow a tamp pad to apply labels at three different product heights in one cycle without mechanical adjustment.
Sequential Part Clamping
First stroke (50 mm) brings a clamp to a pre-close position, and the second (100 mm) applies full clamping force, with sensors confirming each stage via the built-in magnet.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X100X50S the Right Cylinder?
Choose the SCT32X100X50S when your process needs four distinct linear positions without the complexity of two separate cylinders and external hard stops. The 100 mm and 50 mm stroke sections provide an asymmetric position set ideal for a two-step feed followed by a shorter final placement. If you need more force per section, step up to the 40 mm bore, which provides 628 N of push at 0.5 MPa.
For replacement, match the 32 mm bore, both stroke lengths (100 mm and 50 mm), the PT port thread, and the built-in magnet. This model uses a basic mount; if your application requires pivoting, consider the same code with a CA rear clevis.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 100 + 50 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 SCT32X100X50S FAQ
It provides four discrete rod positions: 0 mm (fully retracted), 50 mm (stroke2 only), 100 mm (stroke1 only), and 150 mm (both strokes extended). The positions are fixed by the two section strokes and are not infinitely adjustable.
No. Like all standard pneumatic cylinders, the SCT32X100X50S will drift or drop if pressure is lost or a valve is centered. To hold a load at a specific stop without live pressure, you must add an external rod brake or a pilot-operated check valve.
