Euchner-U.S.A., Inc. Non-Contact Read Head CEM

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. Features Safety switch with guard locking Integrated transponder coding Status LED's High locking forces up to 1,000 N (225 lb) Digitally coded sensor Battery free actuator No maintenance High level of vibration resistance High level of tamper resistance available Optional adjustable adhesive force Benefits Achieves the highest level of safety when used in conjunction with CES evaluation module. Approved for safety category 4 according to EN 954-1 Highest protection against tampering Non-contact system Non-contact system Overcomes misalignment issues Vibration resistant Fault diagnostics Minimizes down-time Operates under extreme environmental conditions e.g. dirt, moisture, ambient temperature Technical Actuator with electromagnet holding force Aluminum housing Fully encapsulated plastic read head and actuator Galvanized steel electromagnet and plate Environmental Protection IP67 - oil and dust tight, and water resistant Ambient operating temperature -25 to 50°C Inductive sensing Switching distance (depending on configuration) On-2mm minimum Off-20mm maximum Electromagnetic holding force CEM-A-LE05K-S2 500 N (112 pounds) CEM-A-LE05R-S2 500 N (112 pounds) without remanence CEM-A-LH10K-S3 1000 N (225 pounds) CEM-A-LH10R-S3 1000 N (225 pounds) without remanence
