General Magnetically coded safety switches CMS The advantages of magnetically coded safety switches Magnetically coded safety switches are interlocking devices that are designed to protect people and machines. Compared with electromechanical safety switches, they are used if: f Non-contact safety door monitoring: no mechanical wear on the sensor hygiene requirements must be met (e.g. in the food industry) f a precise door guide is not possible f compact dimensions are required. The EUCHNER safety system CMS is based on the magnetic principle. The tamper-proof, coded system was specifically...

General System components at a glance Evaluation units Using internal relays, CMS evaluation units switch the safety circuit depending on the position of the contacts in the read head. Selection of the evaluation unit depends on the number of read heads to be connected and on the Performance Level to be achieved according to EN ISO 13849-1 by the overall system. Depending on version, up to 30 read heads can be connected. CMS evaluation units feature 1 to 2 safety contacts, an auxiliary contact and a connection for a feedback loop. Depending on version, the evaluation unit features...

General System components at a glance Safety Relays ESM Safety relays series ESM perform safe evaluation of connected components such as mechanical safety switches, emergency stop devices and electro-sensitive protective equipment, and safely shut down the hazardous machine functions. Various safety relays to which extension modules can be added on the output side are available for the safety system CMS. The advantage of the ESM modular principle is that different safety evaluations can be implemented with only a few module variants. The safety relays can be operated with various types of...
