5mm & 12mm Metal Housing LDR Light Sensor with 100VDC Max Voltage and -30°C to +70°C Operating Range
This 5mm and 12mm CdS photoconductor features a durable metal housing designed for harsh industrial environments with operating temperatures up to 70°C.
The Light Dependent Resistor (LDR) is manufactured using semiconductor materials that exhibit photoconductive properties. Electrical conductivity changes proportionally with light intensity - higher illuminance results in lower resistance values. Available in 5mm and 12mm diameters to meet diverse application requirements.
