Hall Effect Proximity Sensors 

Proximity Sensors

By Jess Buskirk Proximity sensors measure distances without requiring physical contact with the object being measured. Proximity sensing utilizes various forms of technology. All proximity sensors emit a field, and an object, often called the target, triggers the sensor when it enters the field. The type of target object dictates the kind of proximity sensor you need. Inductive proximity sensors are ideal for metallic objects while capacitive ... Read more
