Capacitance is the ability of a system to store an electric charge. In a capacitive sensor, two electrodes are separated by a dielectric (air, liquid, or solid material), forming a capacitor. When an object enters the electric field generated by the sensor, it alters the capacitance. This change is detected and interpreted by the sensor electronics.
Capacitive sensors are versatile tools widely used across industries for their reliability, precision, and ability to operate without physical contact. https://www.rechner-sensors.com/en They play a crucial role in automation, consumer electronics, and various other applications requiring sensitive and non-intrusive detection capabilities.
Capacitive sensors, often referred to as KAS sensors (Kapazitive Sensoren in German), are devices used to detect the presence or proximity of objects by measuring changes in capacitance. Used in manufacturing for object detection and quality control. Touchscreens on smartphones and tablets utilize capacitive sensing. Capacitive switches and controls in appliances.
