Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

Proximity sensors, which are designed to detect the presence of nearby objects without any physical contact, have evolved from narrow application in industrial automation systems into broad use. They ...

Proximity detection enables a system to make a decision based on the relative distance of an object to the proximity sensor. The purpose of proximity detection in most applications is to enable or ...
