CDQ2B25-30DCZ Applications
The CDQ2B25-30DCZ adds a rubber bumper to the standard 25 mm bore compact cylinder, absorbing impact energy at both stroke ends. This makes it well suited to higher-cycle or higher-speed applications where metal-to-metal end contact would generate noise, shock or premature wear, such as reciprocating feeders, stoppers and pick-and-place tooling. The through-hole body and built-in magnet keep installation and position sensing straightforward in tight machine envelopes.
