CDQ2B20-40DZ Applications
This is the baseline 20 mm bore, 40 mm stroke compact cylinder for space-restricted automation: jig clamping, stopper and lifter duties, small gate and shutter actuation, and pick-and-place sub-motions where a full-size cylinder will not fit the envelope. The standard female-threaded rod end accepts a stud or screw-in tooling adaptor. The built-in magnet plus Z auto switch groove means position feedback can be added later without changing the cylinder.
