inductive proximity switch
As a key component in industrial automation, the inductive proximity switch can detect metal objects without any contact between them. The principle on which it relies can be seen in operation at many places: An alternating magnetic field is generated by this device and induces voltage in an object near enough to be affected. The main functions of an inductive proximity switch are, for instance, to see if there is anything there or not and count up objects as they pass by him. The fact that it can function well under harsh environments, is solid-state reliable and has a fast response time all increases its value. Typical applications of such sensors span a range including manufacturing (to test for the proper finish on metal surfaces before leaving them behind); industrial robot ROBOTICS. Material handling areas where positions are critically defined--In both cases detecting metals in particular is vital.
