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 CEM actuators are uniquely coded and cannot be bypassed by any means. The CEM has a digitally coded actuator with an electromagnet built into housing. The electromagnet will hold the guarding during the operation.

TYPICAL APPLICATIONS INCLUDE

Due to the unique capabilities of this product, it is suitable almost anywhere where safety and reliability is of the utmost of concern.
