CD85N12-40C-B Applications
The CD85N12-40C-B adds adjustable air cushioning to smoothly decelerate the piston at stroke ends, reducing impact, noise and wear during faster cycling. It fits medium-stroke positioning, transfer and clamping duties on ISO 6432 machinery, and its built-in magnet enables direct auto switch position feedback for reliable end-of-stroke detection.
