CET-AX Read Heads


CET-AX Non-Contact Safety Switches 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 safety switch CET-AX with guard locking is based on the proven transponder principle. When used in conjunction with the CES evaluation unit, the system provides up to safety category 4.
Note: CET-AX requires the use of an external evaluation unit.
