SMC CDQ2A1215DCZ (CDQ2A12-15DCZ) - Compact Air Cylinder, 12 mm Bore, 15 mm Stroke
SMC CDQ2A1215DCZ Compact Air Cylinder — 12 mm bore, 15 mm stroke, D double acting with C rubber bumper body option, both-ends-tapped mount, built-in magnet. SMC CDQ2A12-15DCZ is a CQ2-Z series standard compact cylinder, double acting, single rod, with a 12 mm bore and 15 mm stroke. The leading D denotes a built-in magnet for auto switch mounting. Mounting code A is both ends tapped. Action code D is double acting. Body option C specifies the cylinder is supplied with a rubber bumper; with no M in the body option the rod end is the standard female thread. The trailing Z is the CQ2-Z auto switch mounting groove, provided on 2 surfaces for bores 12 to 25 mm. Fluid is air, proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa, minimum operating pressure 0.07 MPa, piston speed 50 to 500 mm/s, lubrication not required. Allowable kinetic energy with rubber bumper at 12 mm bore is 0.043 J.

CDQ2A12-15DCZ Applications
Compact cylinders like this one are used where axial space is severely limited, such as small clamping fixtures, part ejectors, stoppers and pick-and-place end effectors inside tight machine envelopes. The C body option adds a rubber bumper that cushions the piston at both stroke ends, roughly doubling the allowable kinetic energy over the plain no-cushion version and reducing impact noise and shock on the workpiece. Both-ends-tapped mounting lets the cylinder be bolted from either the rod cover or head cover face, and the built-in magnet allows D-M9 auto switches in the body groove.
