The AirTAC Airtac MDD Multi-position Double Rod Cylinder MDD32X20S is a genuine MD multi-mount cylinder (double rod), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 N of push force at 0.5 MPa. A bumper cushions the impact.
The MDD32X20S is a 32 mm bore, 20 mm stroke multi-mount cylinder with rods on both sides and a built-in magnet for position switch detection. With rods reducing the effective area on each face, theoretical thrust at 0.5 MPa is 345.6 N per rod side. The compact square body fixes from 6 directions - front, back, left, right, top and bottom - so cylinders mount side by side to save space, with magnetic-switch slots around the body and high guide precision (no added lubricant). Operating pressure is 0.15-1.0 MPa (22-145 psi), medium is air filtered to 40 um, speed is 30-500 mm/s, and cushioning is a bumper.
This is a genuine AirTAC part from the MD family: a standard double-rod variant, not the no-rotating MK version. As the SKU shows, the magnet is included (the S suffix). The port is 1/8" with PT thread. Dimensions and side-load limits vary with stroke, so we confirm exact figures from the AirTAC datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
The 32 mm bore is the largest multi-mount size, delivering 345.6 N theoretical thrust per rod side at 0.5 MPa for the heaviest clamping or pressing jobs. The S suffix in MDD32X20S means the magnet is fitted, so Reed or Hall-effect switches can be seated in the body slots to signal end positions; the magnet-free version drops the S. The double-rod MD layout suits dual-sided actuation; if rod rotation must be prevented, choose the MK family instead. The 20 mm stroke stays well inside the bore 32 table (up to 60 mm), but keep strokes short on this compact cover. Thread can be PT (this model) or G.
Clamp small workpieces in a fixture and confirm open and closed states with switches in the body slots, using both rods for symmetric pads.
Drive a conveyor stopper or gate and verify retraction electrically before the next part is released, fixed to the frame from any of 6 directions.
Install several magnet-equipped 32 mm bodies side by side in a narrow station to index parts and confirm each move at every cycle.
The trailing S means the magnet is fitted, so magnetic switches can be seated in the slots around the body to detect rod position - useful for confirming clamp or gate states. Without the S, the cylinder is the same 32 mm bore, 20 mm stroke, double-rod unit but carries no magnet. Match the suffix to whether your controls need position feedback.
The MDD double-rod design has a rod on both faces, so the piston area on each side is the annular area. Theoretical thrust at 0.5 MPa is 345.6 N per rod side, while a single-rod MD of the same bore pushes with 402.1 N at 0.5 MPa. Overall dimensions and allowable side-load vary with stroke, so confirm them from the datasheet.
