Proximity sensors are electronic devices that detect the presence of nearby objects without physical contact. They work by emitting an electromagnetic field or a beam of radiation and then monitoring the changes in the field or beam caused by the presence of an object. Proximity sensors are commonly used in industrial automation, robotics, and security systems to detect objects and trigger actions based on their presence or absence. They are reliable, accurate, and can operate in harsh environments, making them an essential tool in many industries.
