CDQ2B12-20DZ Applications

A short-body actuator for space-restricted automation: small clamps, indexing stops, ejectors and product diverters on assembly, labelling and electronics handling machines. The 12 mm bore delivers a modest force well matched to light tooling, while the 20 mm stroke covers typical open/close travel of grippers and gates. Auto switch grooves on two faces accept D-series magnetic switches for end-position sensing, and the through-hole body mounts flat against a plate with two bolts.
