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.

*1: All characteristics are measured after exposure to light (100 to 500
lx)
for one to two hours.
*2: The light source is a standard tungsten lamp operated at a color temperature of 2856 K.
*3: Measured 10 seconds after removal of light of 10
lx.

when fully illuminated). The fall time is the time required for the sensor resistance to decay from the saturated conductance
level to 37 %.
