Mrk engineers provides inductive proximity sensors. These sensors have typical application for detecting the presence of a wide range of metallic targets. The detection is accomplished without contacting the target and is mechanically wear free. In principle, an inductive proximity switch comprises of a high frequency oscillator circuit followed by a level detector and a post amplification signal circuit, and drives a buffered solid state output. In effect, when a metallic object is brought within the effective range of the emitted field of the oscillator, a damping action results which reduces the amplitude of the oscillator. This amplitude shift is converted to a digital signal by the level detection [ie, a schmitt trigger] which drives a buffer stage. When the object is removed, the oscillator and the digital signal is turned to its former state. The sensors are available in dc as well as ac versions, with various sizes from m8- m80, with various configurations and sensing distances. Inductive micro box sensor and other types of sensors can be supplied as per the specific requirement.
