Airtac MDD Multi-position Double Rod Cylinder MDD6X30S

The MDD6X30S is an AirTAC multi-mount cylinder, a compact square-body actuator you can fix from 6 directions: front, back, left, right, top and bottom. Because the body bolts down any way you need it and several units can sit side by side, it packs serious function into tight panels. This is the double rod variant in double acting form: a rod extends from both ends of the 6 mm bore body, giving you a 30 mm stroke with working force available at each end, around 10.6 N per rod side at 0.5 MPa (the rod-side figure for this bore). Cushioning at end of travel is a bumper, and the body carries magnetic-switch slots, so reed or hall-effect switches clamp on without brackets.

This is a genuine AirTAC part from the MD standard family, so rod rotation is not actively prevented; if your tooling must stay square, step up to the MK no-rotating family instead. The trailing S in the code means this SKU includes the magnet for position sensing. Operating range is 0.15-1.0 MPa (22-145 psi) on filtered air, running 30-500 mm/s, with M5x0.8 PT ports. Exact envelope dimensions for this stroke and any sizing check can be confirmed from the datasheet on request.

Choose the bore for the force you need: at 0.5 MPa this 6 mm bore delivers around 14.1 N on the push side and 10.6 N on the pull side, so verify your load, friction and orientation before committing. Pick the MDD double rod format when you need a working rod on both ends of the body. Double acting means air drives the piston both ways for controlled extend and retract at 30-500 mm/s. The 30 mm stroke sits within the 35 mm maximum listed for the 6 mm bore, and the body is deliberately compact, so do not stretch an over-long stroke beyond what the short covers are meant to carry. The trailing S adds the magnet; without it the cylinder is identical but blind to switches. Ports are PT thread by default, with G available if your fittings call for it.
