| VISIBLE DETECTOR CdS photoconductive cell Resin coating type (7R,10R type) Standard type designed to withstand high voltage and high power 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 Applications l Small size, thin substrate l Low price l Suitable for high voltage and high power application l Auto dimmer for digital display, CRT and room illumination l Automatic light on/off sensor l Sensor for electronic toy and teaching aid material s Absolute maximum ratings / Characteristics (Typ.
