SMC CDQ2B125DZ (CDQ2B12-5DZ) - Compact Air Cylinder, 12 mm Bore, 5 mm Stroke

SMC CDQ2B125DZ Compact Air Cylinder — 12 mm bore, 5 mm stroke (shortest standard stroke), double acting single rod, built-in magnet, rod end female thread, Z auto switch groove - NOT a 125 mm bore. SMC CQ2-Z Series compact air cylinder, standard type, double acting, single rod. Parsing note: the compressed part number CDQ2B125DZ resolves to CDQ2B12-5DZ, i.e. 12 mm BORE with a 5 mm STROKE - not a 125 mm bore. This was verified on the SMC WEB Catalog, which returns Bore Size 12 (12 mm) and Cylinder Stroke 5 (standard stroke 5 mm) for CDQ2B12-5DZ; 5 mm is the shortest standard stroke listed for the 12 and 16 mm bores (5, 10, 15, 20, 25, 30 mm). Code breakdown: D = built-in auto switch magnet, B = through-hole mounting (standard), 12 = bore, blank port thread = Rc/M thread (M thread on 12-25 mm bores), 5 = stroke, D = double acting, blank body option = rod end female thread, Z = auto switch mounting groove (2 surfaces). Official CQ2 catalog specifications (pneumatic, 12-100 mm bore): fluid air; proof pressure 1.5 MPa; maximum operating pressure 1.0 MPa; minimum operating pressure 0.07 MPa; 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.

CDQ2B12-5DZ Applications

A very short-travel actuator for micro-clamping, pin locating, marking, stamping and hold-down duties where only a few millimetres of movement are required. Typical uses include holding a workpiece against a fixture face, actuating small valves or levers, and short indexing stops in electronics and small parts assembly. Its 12 mm bore and compact body allow several units to be packed close together on a jig plate, and the built-in magnet supports D-series auto switches for end-position confirmation.
