CMS-E-BR/ER/FR Evaluation Units


EUCHNER CMS safety switches are based on the magnetic principle. The tamper-proof coded system was specifically developed to monitor moving machine components and movable safety guards. These are a suitable replacement for safety relays. The CMS-E-BR/ER/FR evaluation modules can have up to 4 read heads attached and have a door monitoring output and feedback loop available. These CMS evaluation modules provide up to Safety Category 4.
