Abstract:
The inductive incremental displacement sensor is characterized in that the first sensor unit and the second sensor unit each have a first inductive sensor and a second inductive sensor disposed at a distance from each other and that the first sensor unit and the second sensor unit deliver a switching signal relevant to a conductive region of the graduated track when the difference or the ratio of the detection signals from the inductive sensors allocated to the respective sensor unit as generated by the conductive region is less than a specifiable threshold. Furthermore, the invention relates to a method for determining the displacement of a first object relative to a second object as well as to an inductive sensor unit.
