Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X200S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X200S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 200mm and 200mm give 3 controllable stop positions across a 400mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X200S
The SCT32X200X200S is a double-acting multi-position cylinder that provides three fixed rod positions: fully retracted (0 mm), mid-stop at 200 mm, and full extension at 400 mm. Each of its two piston sections delivers 402 N of push force at 0.5 MPa, making it a precise actuator for light-duty sorting or diverting tasks where intermediate stops are required.
Equipped with a built-in magnet, this model accepts CMSG, DMSG, or EMSG sensors directly on its tie-rod barrel for non-contact position sensing. The 12 mm diameter rod and PT1/8 ports keep the footprint compact, while the 21 mm air cushion at each end absorbs energy quietly at the end of stroke.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X200S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X200S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 200 / 200 mm |
| Total travel | 400 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 200 mm |
| P2 (both extended) | 400 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 SCT32X200X200S Is Used
3-Position Sorting Gate
Directs packages to three separate conveyor lanes by stopping the rod at 0, 200, and 400 mm, controlled by pressurizing one or both cylinder sections.
Two-Depth Marking Fixture
Brings a stamp or laser head to a clearance position, a shallow mark depth, and a deep mark depth using the three discrete rod stops.
Multi-Stop Clamping
Applies a light clamp force at 200 mm and full clamp force at 400 mm by engaging the second piston section, simplifying low/high-pressure circuits.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X200S the Right Cylinder?
Select the SCT32X200X200S when your application needs three defined stopping points without the complexity of two separate cylinders and external stops. If you require higher force, consider stepping up to the 40 mm bore, which provides 628 N of push per section at the same pressure. For a direct replacement, match the 32 mm bore, both 200 mm strokes, PT port thread, and the -S magnet option. Ensure any guided loads are supported externally, as the tandem design does not constrain rod rotation.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 200 + 200 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 SCT32X200X200S FAQ
It provides three distinct rod positions: 0 mm (fully retracted), 200 mm (first section extended), and 400 mm (both sections extended). The two equal strokes create three stops.
Each piston section generates 402 N of push force and 345 N of pull force when operated at 0.5 MPa. The force does not double; each section acts independently.
