Explanation: A proximity relay is a type of relay that uses an inductive or capacitive sensing element to detect the presence or absence of an object. These relays are commonly used in industrial applications to detect the position of moving parts or to sense the presence of a specific object. They can also be used in security systems to detect the presence of people or vehicles. They are versatile and are able to detect a wide range of materials, including metal, plastic, and glass, and can detect objects through non-metallic barriers.
