Airtac MID Series Double Rod Mini Cylinder MID12X75S
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID12X75S is a genuine double acting, double rod round-body mini air cylinder with a Ø12mm bore and 75mm 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 MID12X75S
Delivering 42.4 N of thrust at 0.5 MPa in both directions, the AirTAC MID12X75S is a double-acting, through-rod mini cylinder built for symmetrical motion. Because a Ø6 mm piston rod exits both end covers, the extend and retract areas are identical, completely eliminating the force differential found in single-rod units. The twin-rod geometry also resists rotation and side loads, providing steadier guiding for light-duty tasks without requiring an external guide rail.
Constructed with a stainless-steel round barrel and riveted rolled ends, this model offers reliable mild corrosion and washdown resistance. It uses the ISO 6432 mounting interface for easy integration into standard mini brackets. The -S suffix denotes a built-in piston magnet, enabling position sensing with CMSG, DMSG, or EMSG switches. Operating on a 30-800 mm/s speed range with an M5x0.8 port, it provides a safe working load of roughly 25 N, easily moving about 2.2 kg vertically each way with a 2:1 safety margin.

Where the Airtac MID Series Double Rod Mini Cylinder MID12X75S Is Used
Symmetric Shuttle Transfer
With 42.4 N of equal force both ways, this cylinder smoothly pushes a small parts tray back and forth between two machining stations without stroke asymmetry.
Back-Rod Switch Tripping
The rear protruding rod is used to mechanically trip an external limit switch, while the internal -S magnet handles primary position sensing via DMSG reed switches.
Anti-Rotation Guiding Push
Twin rods resist torsional twist while pressing a delicate 2 kg electronic connector into a housing, maintaining precise alignment without an external guide.
Is the Airtac MID Series Double Rod Mini Cylinder MID12X75S the Right Cylinder?
When sizing this bore, step down to the MID10X75S for lighter duties (33.0 N @0.5 MPa) or move up to the MID16X75S when your application demands greater force (86.4 N @0.5 MPa). The double-rod layout is specifically advantageous here if you need to attach a stop or flag to the back rod, trip a remote switch, or drive a second load simultaneously.
Keep in mind that the fixed TPU bumper pads only soften the stroke end; they do not lock the piston. If air pressure drops, the cylinder will drift, so fit an external rod lock or pilot check valve for held loads. For mounting, utilize LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is unavailable for this double-rod variant), and leverage the internal magnet for non-contact sensing.
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 MID12X75S FAQ
Yes, force is equal both ways because the through-rod design means both faces use the rod-side area. It delivers 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a maximum theoretical output of 8.6 kgf at 1.0 MPa.
The -S suffix indicates a built-in magnet, allowing you to mount CMSG, DMSG, or EMSG switches. The double-rod design resists rotation and side load, while the rear rod end is free to carry a flag or drive a secondary load.
