CD85N20-25-B Applications

Use this short-stroke C85 cylinder for compact clamping, indexing, part ejection and small gate or shutter actuation on packaging, assembly and material handling machines. The 25 mm stroke with rubber bumper suits light loads and moderate cycle rates where end-of-stroke impact energy stays within 0.27 J. The built-in magnet lets D-series auto switches, mounted with bands, confirm rod position without extra sensors, and the ISO 6432 round body drops directly into existing mini-cylinder mountings.
