VISIBLE DETECTOR
CdS photoconductive cell
Metal package type
Hermetically sealed for high reliability
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.
