SMC CDQ2A1620DZ (CDQ2A16-20DZ) - Compact Air Cylinder, 16 mm Bore, 20 mm Stroke
SMC CDQ2A1620DZ Compact Air Cylinder — 16 mm bore, 20 mm stroke, D double acting with no C or M body option (no cushion, rod end female thread), both-ends-tapped mount, built-in magnet. SMC CDQ2A16-20DZ is a CQ2-Z series standard compact cylinder, double acting, single rod, with a 16 mm bore and 20 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. No body option letter follows the D, so the cylinder is supplied without a rubber bumper and with the standard rod end 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 without cushion at 16 mm bore is 0.038 J.

CDQ2A16-20DZ Applications
One of the most widely used sizes in the CQ2 compact range, this 16 mm bore, 20 mm stroke cylinder handles clamping, part ejection, stopping, gating and small transfer motions where a full-size round-body cylinder would not fit. Both-ends-tapped mounting means it can be bolted from either the rod or head cover, simplifying installation in dense tooling plates. The rod end female thread takes a screw or stud directly. The built-in magnet allows D-M9 series auto switches to be fitted in the body groove, giving reliable extended and retracted confirmation signals to the machine controller.
