Inductive Proximity Sensors and Their Ability to Detect Objects at Distance
Inductive proximity sensors are an important tool utilized in many industries, as they provide a cost-effective way to detect the presence of an object without contact. These sensors use electromagnetic fields to detect objects within their sensing range. Depending on the type of inductive proximity sensor, certain objects can be detected at a further distance than others.
Metal Objects
Metal objects are the easiest objects for inductive proximity sensors to detect at a distance. These sensors are able to detect metallic objects up to a distance of two to three times the sensor’s sensing range. For example, a sensor with a sensing range of 10mm would be able to detect metal objects up to a distance of 20 to 30mm. This makes metal objects the best type of object for inductive proximity sensors to detect at the farthest range.
Non-metallic Objects
Non-metallic objects are more difficult for inductive proximity sensors to detect at a distance. These sensors work best when the object is made of a conductive material, such as metal. Non-metallic objects can be detected at a distance, but the range is not as far as metal objects. Non-metallic objects can typically be detected up to a distance of half of the sensor’s sensing range. For example, a sensor with a sensing range of 10mm would be able to detect non-metallic objects up to a distance of 5mm.
Conclusion
Inductive proximity sensors are an important tool for detecting the presence of objects without contact. Depending on the type of object, these sensors can detect objects up to a certain distance. Metal objects are the best type of object for inductive proximity sensors to detect at the farthest range, whereas non-metallic objects can typically only be detected up to a distance of half of the sensor’s sensing range.
