The XCKJ 10513 model exemplifies a limit switch model with a specialized actuator (roller lever or plunger) meant for ensuring positional accuracy under extreme conditions. The contacts are hermetically sealed, as in food processing and mining, and safeguard against dusty or humid environments. Heavier 1 million cycles of operation guarantees reliability in high-cycle applications. Panels in control centers are easier to wire with quick-connect terminals, which saves time and boosts productivity.
