## Description

CdS photoconductive cells utilize photoconductive effects in semiconductors that decrease their resistance when illuminated by light. These sensors are non-polar resistive elements with spectral response characteristics close to the human eye (luminous efficiency), thus making their operating circuits simple and small. PART NO：LXD20537A Allowable Power Dissipation ( PD ) .......... 500 mW ( Derate above 25 ℃：1.0 mW/℃ ) Maximum Applied Voltage (at 25℃) .......... 500V DC or AC VDC Ambient Temperature Range ( TA ) .......... -40 ～+75 ℃ Soldering Temperature*（0.118 inch from base for 3seconds with heat sink）.......... 260℃ Light Resistance at 1ftc .......... 20-30KΩ Dark Resistance at 0 Lux*2..........2.0/MΩ Peak Spectral Response..........560Nm ※Light Resistance: Measured at 1ftc with standard light A (2856K color temperature) and 2hr pre-illumination at 40-60ftc prior testing.  ※2Dark Resistance:Measured 8 seconds after closed 0ftc.

## Features
