Capacitive switch that detects nonconductive objects beyond metals. It can sense liquids and solids such as plastic, water, glass, and oil. When an object enters the sensing field, it outputs a control signal for noncontact switching. Widely used in automatic control industries for detecting objects, controlling processes, and providing noncontact switching. Key benefits Noncontact sensing reduces mechanical wear and contamination risk. Detects a wide range of materials, including liquids and plastics. Easy integration with standard control circuits that require a switch signal. Applications and scenarios Presence detection on packaging or assembly lines for plastic or glass parts. Detection of liquids such as water or oil in containers or tanks where a nonconductive liquid is present. Noncontact switching to actuate conveyors, feeders, or alarms in automatic control systems.
