SMC CDQ2A2550DMZ (CDQ2A25-50DMZ) - Compact Air Cylinder, 25mm Bore, 50mm Stroke
SMC CDQ2A2550DMZ Compact Air Cylinder — 25mm bore, 50mm stroke, double acting, standard type with rod end MALE thread (DMZ). SMC CDQ2A25-50DMZ is a CQ2-Z series compact air cylinder, standard type, double acting, single rod. Bore size 25 mm with a 50 mm standard stroke - the longest stroke offered on the 25 mm bore in this batch. Mounting style A = both ends tapped. The leading D denotes a built-in magnet, making the cylinder auto switch capable; the trailing Z denotes the auto switch mounting groove (2 surfaces on bore sizes 12 to 25 mm). Body option M = rod end male thread, which distinguishes this DMZ variant from the plain DZ (rod end female thread) cylinders in the same bore family. Port thread is the M thread type (M5 x 0.8) used on bores 12 to 25 mm. Supplied without auto switches fitted.

CDQ2A25-50DMZ Applications
The CDQ2A25-50DMZ combines the largest stroke of the 25 mm bore group with a male-threaded rod end, so knuckle joints, floating joints, clevises and rod end nuts thread on directly. That makes it the right pick for linkage-driven motion - swing arms, tilting chutes, transfer pushers, guard and door actuation - where the load is not bolted flush to the rod face. The built-in magnet supports auto switch position sensing in the side groove, and the both-ends-tapped body keeps installed depth to a minimum.
