The assembly is offered with either PCBoard through hole pins (OPB732) or 24” (610 mm), 26 AWG wires (OPB732WZ), and uses an opaque housing to reduce the sensor’s 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. While an object is in the reflective path of the device, light from the LED will be reflected back to the housing irradiating the surface (base) of the phototransistor. When Infrared light strikes the phototransistor, the transistor becomes forward biased and is considered to be in the “ON” state, providing an IC(ON) current proportional to the light striking the phototransistor. With the Infrared light from the LED not being reflected to the phototransistor, the phototransistor turns “OFF,” minimizing the IC(ON) current. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
