ZapFREE® Fiber Optic Microswitch

MR386 Fiber Optic Microswitch GIF

The MR386 ZapFREE® Fiber Optic Microswitch paired with a MR380 series Controller provides a innovative signaling solution that can be deployed in challenging and hazardous environments over long distances. The switch sensor employs a photo interrupt scheme operating over a duplex multimode optical link that allows for reliable signal detection. This product provides the same mechanical attributes and form factor as ubiquitous electrical micro switches.
