CES-A-S5H Safety Switch


EUCHNER CES Category 4, Non-Contact Safety Systems are used to monitor the position of movable machine guarding by means of Inductive Coding. These systems are designed for use in areas where a high level of tamper resistance and safety is required. These systems feature an inductive read head, evaluation unit / safety module, and a digitally coded actuator. Unlike universally coded magnetic switches, the CES actuators are uniquely coded and cannot be bypassed by any means. The CES-A-S5H is an evaluation unit and read head in one. 14 different position actuators and 1 safety actuator can be detected. Four binary outputs indicate the number of the actuator being detected.
