| Slotted Switch OPB885Z Features: * * * * * 26 gauge wired assembly Non-contact infrared switch Opaque plastic housing 0.375" (9.525 mm) slot width 0.595" (15.113 mm) slot depth Product Photo Here Description: OPB885 uses an Infrared LED and a phototransistor in a slotted switch configuration. The assembly has 24" (609.600 mm) wires on each terminal and uses an opaque housing to reduce the sensor's ambient light sensitivity. Each discrete has an 0.050" (1.270 mm) aperture that focuses the switching sensitivity and limits ambient light absorption by the phototransistor. The housing is made from an opaque plastic with IR transmissive plastic in the front of each aperture to provide dust protection. The phototransistor can be configured as a common collector or common emitter device. When the gap is unobstructed or has material that is transmissive to infrared light from the LED, the light will penetrate the housing and aperture to irradiate 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 that is proportional to the light striking the phototransistor. As the light is blocked by using an opaque object that blocks the infrared light from the LED to the phototransistor, the phototransistor turns "off," minimizing the IC(ON) current and thus allowing the electrical state to be switched.
