inductive sensor
An inductive sensor is an electronic device that can sense whether metallic objects are present or absent in the vicinity without contact with it, even if they are close together. The main applications of this kind of sensor including position detection, counting and material identification. Inductive sensors rely upon their technological advantages for non-contact detection, ability to withstand harsh environments and compatibility with different metals. These devices work by creating a magnetic field and then measuring changes in that field when there is an object nearby made of any metal but copper or aluminum. Inductive sensor applications are extensive. These functions, including automatic operation, security and safety enhancement in traffic systems, have earned them great favor at home and abroad where the desired results they provide perfected our lives that much more efficiently.
