A proximity switch is an essential electronic device used to detect the presence or absence of an object without physical contact. Commonly found in automation systems, these switches operate based on electromagnetic fields, capacitive sensing, or optical detection. They play a crucial role in various applications, from industrial machinery to smart home devices, enabling efficient operation and safety. By detecting objects at a close range, proximity switches streamline processes, enhance productivity, and reduce wear and tear on mechanical components. Their reliability and versatility make them a preferred choice in modern technology, driving innovation across multiple industries
