Abstract
Eddy-current type proximity sensor is a non-contact type sensing device to detect the approach of a conductor. This paper investigates electromagnetic properties of the proximity sensor with magnetic flux shield which has closed magnetic circuit geometry by FEM analysis and experiments. Although it has closed magnetic flux path, its sensing property is enhanced compared with the conventional proximity sensor
