Airtac MID Series Double Rod Mini Cylinder MID12X50S
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID12X50S is a genuine double acting, double rod round-body mini air cylinder with a Ø12mm bore and 50mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MID Series Double Rod Mini Cylinder MID12X50S
Delivering 42.4 N of thrust in both directions at 0.5 MPa, this stainless steel round-body mini cylinder uses a through-rod design to equalize extend and retract forces. The twin Ø6 mm rod resists rotation and side load, providing steadier guiding without an external guide for light jobs. Because the rear rod end exits the back cover, it is free to trip a switch, carry a stop flag, or drive a second load. With a safe working load around 25 N, it can vertically lift about 2.2 kg each way with a 2:1 margin.
Built with a riveted stainless barrel and rod, it handles mild washdown and corrosion. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG switches. It uses the ISO 6432 mounting interface for standard mini brackets, features M5x0.8 ports, and relies on fixed TPU bumper pads to decelerate the stroke end.

Where the Airtac MID Series Double Rod Mini Cylinder MID12X50S Is Used
Symmetric Parts Shuttle
Drives a 2.2 kg workpiece carrier back and forth on a low-friction guide, using the equal 42.4 N force to push and pull components into a test fixture.
Back-Rod Switch Trip
Uses the protruding rear rod end to physically trip a limit switch or flag, confirming stroke completion without needing an internal sensor on that side.
Anti-Rotation Label Press
Steadily presses labels onto small cartons, relying on the twin Ø6 mm rod to resist twisting and side load during the 50 mm downstroke.
Is the Airtac MID Series Double Rod Mini Cylinder MID12X50S the Right Cylinder?
If you need less force, the MID10 offers 33.0 N at 0.5 MPa; if your payload is higher, the MID16 provides 86.4 N. Choose this double-rod model when you need anti-rotation stability, a back-rod stop, or symmetric shuttle movements. The twin rod keeps the payload steady without external guides for light tasks.
Mounting options include LB foot, FA flange, and TC trunnion, but the SDB pivot block is not available on this variant. Note that a plain cylinder does not hold its load on air loss; the piston drifts and the TPU bumper only softens the stroke end. For a held load, use an external rod lock or pilot check valve. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MID Series Double Rod Mini Cylinder MID12X50S FAQ
Because a rod exits both ends, force is equal both ways. It delivers 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a maximum theoretical force of 8.6 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. However, it does not hold position on air loss; the piston drifts. For holding, use an external rod lock or pilot check valve.
