MR380 1-3 Universal MM/SM E-Stop and Switch Controller

MR380 1-3 Universal MM/SM E-Stop and Switch Controller

MR380 Fiber Optic Signaling Sensors are used anywhere where conventional electromechanical controls cannot be used – both harsh and hazardous environments. The MR380-1-3 Universal Controller Module is the active optical and electrical interface for all MR380 series ZapFREE® Emergency Stop, Microswitch, and other Signaling Sensor products. This controller is compatible with both multimode (50/125 and 62.5/125) and single mode (9/125) based sensors in the MR380 series.
