Sensing the position or state of a machine is often the first step to monitoring its overall equipment effectiveness (OEE). A proximity sensor can get this data without interfering with the machine itself. There are more than a dozen different types of proximity or prox sensors, including radar, lidar, inductive, optical, and Hall effect.
In this lesson, learn how to wire a proximity sensor. We will use a hall effect sensor, which senses a magnetic field. You can apply the same concepts to monitor a digital signal from any device.
See Automation 101: Wire a Proximity Sensor (webpage) for a parts list, technical documents, wiring diagrams and more information.
