OPB885Z Featur es : 24 (610 mm) long 26 gauge wired assembly Non-contact infrared switch Opaque plastic housing 0.375 (9.5 mm) slot width 0.595 (15.1 mm) slot depth De scr ip ti o n : OPB 885 uses an Infrared LED and a phototransistor in a slotted switch configuration. The assembly has 24 (610mm) 26 AWG wires on each terminal and uses an opaque housing to reduce the sensors ambient light sensitivity. Each discrete has an 0.050 (1.27 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. In the normal unobstructed slot, infrared light from the LED, radiates the phototransistor and becomes forward biased and is considered to be in the on state, providing an I current that is proportional to the light striking the phototransistor. C(ON) As the light is blocked by using an opaque object that blocks the infrared light from the LED to the phototransistor, the phototransistor turns o,ff minimizing the I current and thus allowing the electrical state to be considered switched. C(ON) Custom electrical, wire and cabling and connectors are available.
