Apparatus for detecting a magnetic field, the vertical hall - sensor and the magnet has been shown and described a detection method

摘要

Apparatus for detecting a magnetic field with a vertical hall - sensor, which has the following features:a hall - effect - region (11); anda plurality of contacts (21, 24), which in the or on a surface of the hall - effect - region are formed, the contacts in a sequence are arranged along a path extending between a first end and a second end of the hall - effect - region extends;the apparatus is designed in such a way thatthe plurality of contacts at least four spinning - current - contacts and at least two only - supply - contacts;the spinning - current - contacts according to a spinning - current - scheme alternately as supply contacts and act as a detection of contacts;the at least four spinning - current - contacts along a middle section of the path are located; andthe at least two only - supply - contacts on a distributed manner on opposite sides of the central section are configured and arranged for this purpose, the hall - effect - region according to a widening of the spinning - current - diagram to be supplied with electric energy.
