Title:
POSITION SENSOR
Document Type and Number:
WIPO Patent Application WO/2016/157900
Kind Code:
A1
Abstract:
A sensor includes a source including an electromagnetic structure generating an electromagnetic near-filed upon receiving energy and a detecting unit including at least one coil arranged in proximity to the source such that the electromagnetic near-filed induces, via an inductive coupling, a current passing through the coil. The sensor also includes a measuring unit for measuring a voltage across the coil and a processor for detecting a presence of a target structure in proximity to the source upon detecting a change in a value of the voltage. The target structure is an electromagnetic structure moving at a distance from the source.
