CDQ2B20-45DZ Applications
The 45 mm stroke gives a little more reach than the common 40 mm variant while keeping the same short 20 mm bore body, which suits stopper and lifter mechanisms, small door and flap drives, and feed or ejection strokes on compact assembly cells. The through-hole mount bolts straight through the body into a plate, and the built-in magnet with the Z auto switch groove supports flush-fitting reed or solid-state switches for end-of-stroke confirmation.
