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
l Variety of package size
l Highly resistant to moisture and dust
Applications
l Sensor for office machine
l Safety device for heating system and boiler
(flame monitor for oil burner)
l Night/day check sensor and sunlight sensor for air conditioner
l Alarm and safety sensor

*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 10lx.
*4: Typical gamma characteristics (within0.10 variations) between 100lx to 10lx
E
, E
: illuminance 100lx, 10lx
R
, R
: resistance at 100lx and 10lx 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 %.
