Function
A ring magnet is connected to the axle of the
sensor crank (rotor).
A hall IC is positioned eccentrically between a
two-piece iron core (stator). It forms a single
unit together with the evaluation electronics.
Depending on the position of the ring
magnet, the magnetic field which penetrates
the Hall IC changes.
The resulting Hall signal is converted by the
evaluation electronics into a voltage signal
proportional to the angle. The control unit
J197 uses this analogue voltage signal to
determine the current vehicle level.

The angle sensor described here is
also used for the automatic
headlight range control system.
A total of 3 sensors are fitted into
vehicles with automatic headlight
range control.
