CEM-AY-C40 Safety Switch


EUCHNER CEM-AY-C40 Safety Switches are used for process protection. They work by means of integrated CES-AR 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 with integral evaluation unit, electromagmet latch, and a digitally coded actuator. These switches are good for Safety Category 4 and PL e according to EN ISO 13849-1 for door position monitoring.
