uses an Infrared LED and a phototransistor in a slotted switch configuration. The assembly has 24鈥?/div>
(609.600 mm) wires on each terminal and uses an opaque housing to reduce the sensor鈥檚 ambient light
sensitivity. Each discrete has an 0.050鈥?(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 鈥渙n鈥?state, providing an I
C(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 鈥渙ff,鈥?minimizing the I
C(ON)
current
and thus allowing the electrical state to be switched.
