CES-AH Safety Switch


EUCHNER CES-AH Category 3 / PL d, Non-Contact Safety Switchers 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, and a digitally coded actuator. Unlike universally coded magnetic switches, the CES-AH actuators are uniquely coded and cannot be bypassed by any means. The CES-AH is an evaluation unit and read head in one featuring high current outputs.
