VISIBLE DETECTOR
CdS photoconductive cell
Resin coating type (5R type)
Standard type designed for general-purpose, wide application
CdS photoconductive cells utilize photoconductive effects in semiconductors that decrease their resistance when illuminated by light. These sensors are non-polar resistive elements with spectral response characteristics close to the human eye (luminous efficiency), thus making their operating circuits simple and small.
Features
l Small size, thin package l Low price l Wide range of sensor lineup
Applications
l Programed electronic shutter and stroboscope light control for compact camera
l Auto dimmer for digital display, CRT and room illumination l Sensor for automatic light on/off l Sensor for electronic toy and teaching aid material
