Abstract: A magnetic sensor includes a sensor housing having a front end directed toward a member to be sensed. A magneto-electric transducer is mounted in the sensor housing and disposed adjacent to the front end of the sensor housing. A magnetic flux-collecting chip of a high-permeability material is supported on the front end of the sensor housing. The magnetic flux-collecting chip is disposed forwardly of the magneto-electric transducer. The magnetic flux-collecting chip has an exposed front face directed away from the magneto-electric transducer. The sensing ability or performance of the magneto-electric transducer is substantially determined by a magnetic gap between the front face of the magnetic flux-collecting chip and the member to be sensed.

Abstract: A sensor includes a housing which is narrow at least at its front portion. An insertion portion of a holder is inserted in the front portion of the housing. A plurality of elongate conductors are printed on an outer surface of the insertion portion of the holder, the conductors extending generally in the direction of the axis of the housing. A sensing element is mounted within the front portion of the housing and is disposed forwardly of the holder. The sensing element has terminals extending therefrom toward the holder in generally parallel relation to the printed conductors. The terminals are soldered respectively to the printed conductors, thereby retaining the sensing element on the holder.
