Magnetic Field Sensitive Sensor
First Claim
1. A sensor comprising at least one magnetic field-sensitive GMR sensor element which is arranged in a housing, wherein the housing additionally includes one magnetic field source each associated to the at least one GMR sensor element,wherein the at least one GMR sensor element is firmly cast into an associated slot in the housing, wherein on at least one side of the slot a projection protrudes into an interior of the housing flush with a side wall of the slot, the projection including mounting recesses for accommodating the magnetic field source.
