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. *4: Typical gamma characteristics (within ±0.10 variations) between 100 lx to 10 lx
γ 100 = 10
log (R100) - log (R10) log (E100) - log (E10)
E, E: illuminance 100 lx, 10 lx x R, R: resistance at 100 lx and 10 l respectively *5: The rise time is the time required for the sensor resistance to reach 63 % of the saturated conductance level (resistance when fully illuminated). The fall time is the time required for the sensor resistance to decay from the saturated conductance level to 37 %.
