ABSTRACT:
This invention is a magnetic-field sensor assembly comprising a preformed housing shell having a first end which includes an opening, and a second end which includes a window and having a cylindrical shape with a flattened portion to produce a truncated circular cross-section, a sensor package including an integrated-circuit magnetic-field-sensor chip encapsulated in a protective body with first and second opposite and mutually parallel faces and a plurality of integral conductive leads, each lead having a proximal portion, a distal portion, and a central portion, the proximal portion of each of said plurality of leads extending from said body, the central portion of said plurality of leads extending away from the body and positioned substantially normal the faces of the body, said sensor-package body being positioned in said housing shell part way through said window with said one body face extending outwardly from said housing shell and with said lead distal portions extending from said housing shell through said opening, a magnet having a first end and a second end and positioned in said housing shell with said first end adjacent to said second sensor-package body face, and an endcap adapted to close said opening in said housing shell.
