Capacitive Proximity Sensors: Working Principle, Ranges

WebA touch switch, as the name suggests, is one of various types of activation switches that need only be subjected to some degree of physical contact/pressure from an operator or object in order to actuate. Touch switches are, in many ways, the simplest kind of tactile sensor; they are most often a type of binary on/off electronic switch that ... In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric constant different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity, pressure, position and displacement, force, humidity, fluid level, and acceleration.
