Eaton Electrical Proximity Sensors include a range of inductive and capacitive proximity sensors. Inductive sensors are immune to dirt, grease, and other adverse conditions. These proximity sensors can detect metallic targets through non-metallic barriers and lightweight or small objects that are undetectable by mechanical limit switches. Eaton capacitive proximity sensors detect both metallic and nonmetallic targets. These capacitive sensors are ideal for liquid level control and sensing powdered or granulated material.
