## Description

25pcs 8-20 k ohm Photoresistor LDR Photo Resistors Light-dependent /0.2 x 0.169 Inches Photo Light Sensitive Resistor Photoresistor Optoresistor / SG5528 Photoresistor LDR Photo Resistors Light-dependen The SG5528 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. Applications ● Camera Exposure Control ● Auto Slide Focus - dual cell ● Photocopy Machines - density of toner ● Colorimetric Test Equipment ● Densitometer ● Electronic Scales - dual cell ● Automatic Gain Control - modulated light source ● Automated Rear View Mirror Digital Applications: ● Automatic Headlight Dimmer ● Night Light Control ● Oil Burner Flame Out ● Street Light Control ● Absence / Presence (beam breaker) ● Position Sensor

## Features

- ● Epoxy encapsulated
