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
• Variety of package size
• Highly resistant to moisture and dust

APPLICATIONs
• Sensor for office machine
• Safety device for heating system and boiler (flame monitor for oil burner)
• Night/day check sensor and sunlight sensor for air conditioner
• Alarm and safety sensor
