CES-AZ-AES Evaluation Units


EUCHNER CES-AZ-AES Evaluation Units are used to monitor the position of movable machine guarding by means of Inductive Coding. These RFID 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. The Unicode evaluation unit comes in versions to accomodate 1, 2 or 4 read heads.
One terminal connection set (ordered separetely) is needed for each evaluation unit.
