The OPB732WZ is a long distance Reflective Switch uses an infrared LED and phototransistor in a reflective switch configuration. The assembly is offered with 26AWG wires and uses an opaque housing to reduce the sensor ambient light sensitivity. The emitter and sensor are protected by a clear window, providing a device that can operate in a dusty environment. The phototransistor can be configured as a common collector or common emitter device.
