Capacitive Proximity
Switches

Introduction
❖ Capacitive proximity sensors detects a wide variety of materials with permittivity and can not only detects conductive materials such as iron and metal but also non conductive materials such as plastics water, stone, built in sensitivity allows users to apply in a diverse area of users convenience.
❖ The capacitive proximity switches are used for sensing metallic as well as non metallic material.

The Major Application Of Capacitive Switches :
• Liquid level/Plastic Granules/Component/Sand/Bulk Material Level
• Food/Grain/Paper & Rubber/Glass Industries

Working Principle
The switches works on th principle of resonant oscillator circuit. Two brass plates are used as electrodes of capacitor & the sensing objects acts as a dielectric media. The change in capacitance the object is sensed by a sensing circuit and output signal is generated.

Type : CPS13 - DC/CPS12-AC
