Abstract
Sensor arrangements are disclosed. A magnetic sensor is mounted to a printed circuit board. A pole element is arranged next to the magnetic sensor. The pole element acts as a magnetic field concentrator for the magnetic sensor. A movable magnet may be positioned in proximity to the magnetic sensor and the pole element. The movable magnet may be held in a magnet holding element. The magnet holding element may be attached to a rotatable element, such as a shaft.
