The sensor shown is an inductive barrel prox, which is a common type of proximity sensor utilized in industrial automation. Sensors of this type are triggered when an object of a certain material (depending on the sensor’s detection mechanism) is nearby the sensor. Diffuse or “Reflective” (distinct from retro-reflective)Ī “ barrel prox“ a type of proximity sensor that threads into a tapped hole.Magnetic (Hall Effect) Proximity Sensors.In this article, we’ll look at some of the many different types of proximity sensors that are used in industrial automation. Proximity sensors are a specific subset of sensors in general. As examples, sensors may detect that a part is present, that a part is not present, that an actuator is in a certain position, that a lift is lowered or raised, that a door is open or closed, or that a spring-returned component is a certain distance away. Sensors provide indication to the PLC, robot, or other controller that some physical event has taken place. When you write logic in a PLC that initiates motion, you want to be certain that the motion you are expecting actually occurs.
