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.

 

 

 

The MR386 Microswitch has a standard  V-series form factory and is compatible with Omron and Honeywell microswitch accessories, including lever arms and roller arms. Below is MR386 microswitch with Omron VAL2 Roller Leaf Spring.
