SMC CDQ2A40100DCMZ (CDQ2A40-100DCMZ) - Compact Air Cylinder, 40mm Bore, 100mm Stroke
SMC CDQ2A40100DCMZ Compact Air Cylinder — 40mm bore, 100mm stroke, both-ends-tapped mount, Rc port thread, double acting with rubber bumper and rod end male thread (DCMZ), built-in magnet. SMC CDQ2A40-100DCMZ is a CQ2-Z series compact air cylinder with a 40 mm bore and 100 mm stroke. The CDQ2 prefix denotes a built-in magnet for auto switch mounting; mounting style A is both ends tapped. The blank port-thread symbol specifies Rc port threads. Body options C and M add a rubber bumper and a rod end male thread in place of the standard female rod end. Double acting, single rod. Operating fluid is air, proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa and minimum operating pressure 0.05 MPa. Piston speed range is 50 to 500 mm/s, lubrication is not required (non-lube), and stroke length tolerance is +1.0/0 mm. Ambient and fluid temperature is -10 to 70 C without auto switch and -10 to 60 C with auto switch. Allowable kinetic energy at 40 mm bore is 0.52 J with the rubber bumper fitted. The Z suffix indicates the CQ2-Z auto switch mounting groove, available on four surfaces for bore sizes 32 to 100 mm.

CDQ2A40-100DCMZ Applications
Used where a full-stroke actuator would not fit: clamping, indexing, part transfer and press-fit stations on assembly and packaging machines. The rubber bumper absorbs end-of-stroke impact for quieter, gentler cycling, while the male rod end thread accepts rod clevises, floating joints and knuckle joints directly. Rc ports suit standard tapered-thread fittings, and the built-in magnet allows auto switches to confirm position on any of four body surfaces.
