HIGH RPM PROXIMITY SENSOR

The basic purpose of a proximity sensor is to perceive occurrence of any object without being in contact with it. A proximity sensor makes a field around it by emitting electromagnetic radiations. The beam of electromagnetic radiations traces any object or hurdle in its way. The term target is used for the object that a proximity sensor intuits in its path. The sensor looks for any alteration made in its field. Target usually replaces a certain beam of the field or hurdles its projection. Different fields or sensors are used to detect different targets.
