PROD Model:φ3
Maximum Applied Voltage: the maximum voltage that can be continuously applied to a component in the dark
Dark Resistance: resistance value at 10 seconds after 10Lux illumination is turned off
Maximum Power Consumption: maximum power consumption when the ambient temperature is 25 ° C
Bright Resistance: after 2 hours of exposure with 400-600Lux light, the
test value under 10Lux light of standard light source (color temperature
2856K)
γ Value: logarithm of the ratio of the standard resistance value at 10Lux illuminance to 100Lux illuminance
γ= Lg(R10/R100) /Lg (100/10) =Lg(R10/R100)
A photoresistor is a resistance made of a
semiconductor material whose conductivity changes with the change of
illuminance. This feature is used to make photoresistors of different
shapes and light-receiving areas. Photoresistors are widely used in
toys, lamps, cameras and other industries.
Epoxy encapsulation
Good reliability
Small size
High sensitivity
Fast response
Good spectral characteristics
Applications
They have a very simple structure and they are low cost and rugged devices.They are widely used in many different items of electronic equipment including photographic light meters, fire or smoke alarms as well as burglar alarms, and they also find uses as lighting controls for street lamps.
