Abstract
A magnetic sensor arrangement for determining a position of an actuator may include a magnetic sensor to determine the position of the actuator, where the actuator may be configured to reciprocate along a longitudinal axis of an actuator housing of the actuator, such that at least a portion of the actuator may cross an end plane of the actuator housing when reciprocating along the longitudinal axis, and the magnetic sensor may sense a set of components of a magnetic field generated by a magnet, and determine, based on the sensed set of components of the magnetic field, a position of the actuator along the longitudinal axis of the actuator housing of the actuator, where the magnet may be connected to or forms part of the actuator, and where the magnetic sensor may be connected to the actuator housing, and where a portion of the magnetic sensor may be positioned at least in a first actuator position beyond the end plane of the actuator housing.
