CDQ2B25-15DZ Applications
With a 15 mm stroke this 25 mm bore compact cylinder covers medium-short travel jobs: opening and closing small gates and diverters, lifting or lowering guides, pushing parts off a conveyor line and driving clamp arms on machining fixtures. The very short body height is the main reason to specify a CQ2 over a round-body cylinder in a crowded machine. The built-in magnet and Z auto switch groove let you add position sensing without any external bracketry.
