Capacitive proximity switch is a sensor that senses the presence or position of an object by detecting changes in its capacitance. Due to its sensitive sensing ability towards various materials (including metals, non metals, liquids, etc.), it has been widely used in various fields such as industrial automation, home appliance control, and material detection. Main application: Material detection: In industrial production lines, capacitive proximity switches can be used to detect the presence or absence of materials, liquid level height, etc. For example, in the packaging industry, liquid can be detected inside packaging bottles, or in the food processing industry, the presence of materials on production lines can be detected. Position control and detection: capacitor proximity
