Description
The VT202BE is an electronic component model that falls under the product category of IC chips. It is a type of photoconductive cell used in various circuits and applications.
Semiconductor light detectors can be classified into two major categories: junction and bulk effect devices. The VT202BE belongs to the junction device category and operates in the photoconductive mode. It utilizes the reverse characteristic of a PN junction, acting as a light-controlled current source. The output of the VT202BE is proportional to incident illumination and is relatively independent of applied voltage.
Photoconductive cells like the VT202BE find applications in analog and digital circuits and devices. They are commonly used in camera exposure control, auto slide focus (dual cell), photocopy machines (density of toner), colorimetric test equipment, densitometers, electronic scales (dual cell), automatic gain control with modulated light source, automated rearview mirrors, automatic headlight dimmers, night light control, oil burner flame out detection, street light control, absence/presence (beam breaker) detection, and position sensors.
