CEM Read Heads

PDF

CEM Non-Contact read heads 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, external evaluation unit / safety module, and a digitally coded actuator. A CES read head and a solenoid are integrated into the CEM read head. The CEM read head is connected to the CES evaluation unit with a round M8 plug connector. The CEM actuator has a metal plate in addition to the transponder; this plate acts as an armature for the solenoid coil.
