Abstract

A Hall effect sensor with multiple Hall effect elements, each of the Hall effect elements having a first contact terminal, a second contact terminal, and a third contact terminal arranged along a straight line. The multiple Hall effect elements are electrically connected in series in a closed circuit. The second contact terminals of the Hall effect elements are supply voltage connections or Hall voltage pickoffs, and the applicable second contact terminal of the Hall effect element is a center contact of the Hall effect element. The Hall effect elements form two pairs, and the Hall effect elements of one pair each measure the same component of a magnetic field and an operating current is impressed on the series circuit in the two Hall effect elements of this one pair, and a supply voltage is applied to the Hall effect elements of the other pair.
