About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X150S
The SCT40X30X150S tandem cylinder provides four fixed rod positions: 0 mm, 30 mm, 150 mm, and 180 mm total travel. Each piston section delivers 628 N of push force at 0.5 MPa, driven by a 16 mm diameter rod through PT1/4 ports. The body length A is 235 mm, and the integrated air cushion absorbs 21 mm of end-of-stroke energy.
A built-in magnet is standard on this -S variant, allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for non-contact position feedback. This genuine AirTAC tandem cylinder suits multi-stop tasks where electronic sensing is required without external brackets.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X150S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X150S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 30 / 150 mm |
| Total travel | 180 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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) | 150 mm |
| P3 (both extended) | 180 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT40X30X150S Is Used
Two-Stage Sorting Gate
Diverts packages to three lanes using the 30 mm and 150 mm stops, with the 180 mm position clearing a reject path.
Depth-Selective Press
Sets two distinct pressing depths in a light assembly fixture, using the short stroke for contact and the long stroke for full insertion.
Multi-Stop Pusher
Advances products along a conveyor in two increments, first by 30 mm for orientation, then by 150 mm to the next station.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X30X150S the Right Cylinder?
Choose the SCT40X30X150S when an application needs four distinct mechanical stops from a single compact unit. It replaces setups that would otherwise require two separate cylinders and external hard stops, simplifying plumbing and control logic. For higher thrust, the 50 mm bore SCT offers 982 N of push force per section at the same pressure. As a direct replacement, match the 40 mm bore, both 30 mm and 150 mm strokes, PT ports, and the -S magnet option exactly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 30 + 150 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 SCT40X30X150S FAQ
It has four discrete rod positions: fully retracted (0 mm), the first section extended (30 mm), the second section extended (150 mm), and both sections extended together (180 mm total).
Yes, if the strokes match. The SCT40X30X150S replaces a 30 mm and a 150 mm stroke cylinder in tandem, saving space and eliminating the need for external couplers. Ensure the replacement matches the 40 mm bore, PT ports, and the -S magnet option.
