CES-AR-C Safety Switch


CES Category 4 Non-Contact Safety Switches are used to monitor the position of movable machine guarding by means of Inductive Coding. These systems feature an inductive read head with built-in evaluation and a digitally coded actuator. Unlike universally coded magnetic switches, the CES actuators are uniquely coded and cannot be bypassed by any means. The non-contact safety switch CES-AR C is suitable for systems on which a large number of safety doors need to be monitored. The small design of the actuator and read head (included integrated evaluation unit) allows easy mounting on the safety guard.
