Additional Information

This is a miniature light dependent resistor (LDR), suitable for use in projects which require a device or circuit to be automatically switched on or off in darkness or light.
As the amount of light falling on this LDR increases, its resistance decreases.

The light detector itself is just 5mm in diameter with a clear epoxy finish.

Technical Specifications

Dark resistance: 1 MOhm
Resistance at 10 Lux: 10-20 kOhm
Resistance at 100 Lux: 2-4 kOhm

This LDR can dissipate up to 100mW and can be used in systems with peak voltages from 0-150 Volts DC or AC. Operating temperature is from -30 to +70 degrees Celcius.
