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
