MR387
Emergency Stop Sensor
The MR387 Series Emergency Stop Sensor Systems is a new, innovative emergency signaling system that can be deployed in hazardous environments or over long distances – beyond the capabilities of conventional electromechanical solutions. The MR387 E-STOP system employs a photo interrupt scheme operating over a duplex fiber link – multimode 50/125 or 62.5/125 fiber, 9/125 singlemode fiber or 1mm POF.
The MR387 E-STOP is designed for applications where a system needs to be deactivated when the E-STOP switch sensor is depressed or any system malfunction occurs.
Our FO E-Stop Components can be arranged in different ways, click on the following diagrams for more information:
