Physical and Environmental Characteristics

Photoconductive Cell Typical Application Circuits

General

Light Dependent Resistor is easy to use in projects. It requires a device or circuit to be automatically switched on or off in darkness or light. The resistance will change depending on the intensity of light it is exposed to.

Three material shell:
1.)the epoxy body
2.)the metal body
3.)the glass body
All specification or diameter: 3mm, 4mm, 5mm, 6.5mm, 7mm, 8mm, 10mm, 11mm, 12mm, 20mm, 25mm and so on .

Test Condition

Max. External Voltage: The max. voltage can be consistently imposed in the components in darkness.
Dark Resistance:The resistance which is get from closed the 10 lux light for 10 seconds. Max. Power:When the environment temperature is 25℃ using the biggest power Light Resistance:The resistance which is get after 400-600lux light for 2 hours, test with the standard light (CCT:2854K) 10 lux get the value.
Γ Value: The ratio gets from the standard resistance in 10 lux illuminance and 100lux illuminance’s rate.
Lg (R10/R100)
γ= =Lg(R10/R100)
Lg (100/10)
R10､R100 the resistance value in 10lux and 100 lux respectively. (γ’s tolerance is ±0.1)
