OPB608C Description
OPB608 reflective switches consist of an infrared emitting device (LED or VCSEL) and a NPN silicon phototransistor mounted “side-by-side” on a parallel axis in a black opaque plastic housing. All OPB608’s (except OPB608R) have an emitting device and a phototransistor that are encapsulated in a visible filtering epoxy. The phototransistor responds to radiation from the emitter only when a reflective object passes...
