Product Overview

The VT20N2 is a Photocell or Light-Dependent Resistor in TO-5 type housing. It can provide a very economical and technically superior solution for many applications where the presence or absence of light is sensed or where the intensity of light needs to be measured. Semiconductor light detector can be divided into two major categories junction and bulk-effect devices. The bulk-effect photoconductor has no junction. The bulk resistivity decreases with increasing illumination, allowing more photocurrent to flow. This resistive characteristic gives bulk-effect photoconductor an unique quality signal current from the detector can be varied over a wide range by adjusting the applied voltage. The photocell is thin-film device made by depositing a layer of a photoconductive material on a ceramic substrate.
  • Responsive to both very low light levels and to very high light levels
  • Low noise and distortion
  • Easy to use in DC or AC circuits
  • Suitable for 120/240VAC applications
