Photoresistor 5-10kohm @10Lux LXD3516 Light Dependent Resistor (LDR) Ø3mm CdS Photocell Serie

The LXD3516 CdS photocell consists of a thin film of photoconductive material on a ceramic substrate . A unique method of lead wire attachment provides metallurgical bonding of the wire to the electrode and rigid anchoring of the lead in the ceramic , thus eliminating the need for conductive pastes . A thin plastic coating provides protection for the active surface. These sensors are non-polar resistive elements with spectral response characteristics close to the human eye (luminous efficiency), and the light dependent resistors are available in a wide range of resistance values . CdS photoconductive cells utilize photoconductive effects in semiconductors that decrease their resistance when illuminated by light , thus making their operating circuits simple and small.
