Features:
Description:
OPB732 uses an Infrared LED and Phototransistor in a reflective switch configuration. 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 I
light striking the phototransistor. With the Infrared light from the LED not being reflected to the phototransistor, the
phototransistor turns “OFF,” minimizing the I
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
