It is a component widely used in the automatic control industry for detection, control, and non-contact switching. When the proximity switch is near a target object, it outputs a control signal. As a capacitive proximity switch, it can detect conductive and non-conductive materials, including liquids and powders such as plastic, water, glass, and oil. It is commonly used in machinery, paper manufacturing, and light industry applications for position limiting, orientation, counting, and speed sensing.
