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.

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