SMC CDQ2B1225DMZ (CDQ2B12-25DMZ) - Compact Air Cylinder, 12 mm Bore, 25 mm Stroke
SMC CDQ2B1225DMZ Compact Air Cylinder — 12 mm bore, 25 mm stroke, double acting single rod, body option M = rod end MALE thread (with rod end nut), built-in magnet, Z auto switch groove. SMC CQ2-Z Series compact air cylinder, standard type, double acting, single rod, with rod end male thread. Decoded and confirmed on the SMC WEB Catalog: D = built-in auto switch magnet, B = through-hole mounting (standard), 12 = 12 mm bore, blank port thread = Rc/M thread (M thread on 12-25 mm bores), 25 = 25 mm standard stroke, D = double acting, M = body option 'rod end male thread' (the M is the body option, NOT a port or switch code), Z = auto switch mounting groove (2 surfaces on 12-25 mm bores). This is the male-rod-end sibling of CDQ2B12-25DZ, which has the standard female rod end thread. Official CQ2 catalog specifications for the pneumatic 12-100 mm bore range: fluid air; proof pressure 1.5 MPa; maximum operating pressure 1.0 MPa; minimum operating pressure 0.07 MPa (12-25 mm bore); ambient and fluid temperature -10 to 70 C without magnet, -10 to 60 C with magnet; non-lube; piston speed 50 to 500 mm/s; cushion: without cushion or with rubber bumper.

CDQ2B12-25DMZ Applications
Specified when the load is attached with a nut, knuckle joint or clevis rather than screwed into a female rod end: linkage-driven flaps, single knuckle joints, rod end bearings and lever mechanisms. The 12 mm bore, 25 mm stroke size fits small clamping and pushing duties in assembly cells, electronics handling and packaging equipment. Grooves on two faces take D-series auto switches for stroke-end confirmation, and the through-hole body bolts directly to a mounting plate.
