Abstract
A magnetic sensor includes a housing in which flux producing means which comprises an electromagnet or a permanent magnet is received. A pair of magnetoelectric transducer elements are secured to a surface of the flux producing means which represents a magnetic pole, with a given spacing between the elements. In order to dispose the magnetoelectric transducer elements as close as possible to the outer surface of the housing, the latter is formed with a through opening at a corresponding position. The through opening is covered by a thin shield cap to protect the magnetoelectric transducer elements from a member being detected which is passed in sliding contact with or very close to the outer surface of the housing and to provide an enclosed construction for the housing.
