CMS-R Coded Magnet Switches


EUCHNER CMS safety switches are magnetic (non-contact) read heads that sense a coded magnetic actuator.The read heads only respond to specifically coded actuator types to pervent tampering.CMS evaluation units can be chosen depending on the number of read heads used and the overall system safety category desired.The CMS magnetic systems are particularly suitable for areas where dirt and cleaning are major factors.Actuators and read heads can be fitted behind stainless steel making them ideal for pharmaceutical and food industry applications.
Note: CMS actuators are sold separately.CMS requires the use of an external evaluation unit.
