A sensor system may include a magnet arranged such that a linear position of the magnet corresponds to a position of a trigger element on a substantially linear trajectory, and such that an angular position of the magnet corresponds to a selected position of a selection element, the selected position being one of a plurality of selected positions. The sensor system may include a magnetic sensor to determine the position of the trigger element based on a strength of a first magnetic field component and a strength of a second magnetic field component, and determine the selected position of the selection element based on a strength of a third magnetic field component and the strength of the second magnetic field component. The first magnetic field component, the second magnetic field component, and the third magnetic field component may be perpendicular to each other.

Contactless magnetic sensing trigger system

A sensor system may include an object, a magnet, and a magnetic sensor. The magnet may be connected to the object such that a center of the magnet is offset from an axis of the object. The magnetic sensor may include a first three-dimensional (3D) sensing pixel and a second 3D sensing pixel. The magnetic sensor may be arranged such that the first 3D sensing pixel and the second 3D sensing pixel are at different distances from a tilt point of the object. The magnetic sensor may be arranged such that the first 3D sensing pixel and the second 3D sensing pixel are at different distances from the center of the magnet.

Stray field robust magnetic sensor system for detecting a state of a tiltable and rotatable object

A rotational angle sensor device and a corresponding method are provided. Two signals which have a phase offset with respect to one another are generated based on a modulated magnetic field using a sensor arrangement. Three signals which have a phase offset with respect to one another are generated from the signals.

Rotational angle sensor device and method for determining a rotational angle, and control device for an electric motor

Implementations relate to a sensor assembly for determining rotation about an axis and linear movement parallel to the axis. The sensor assembly comprises a magnetic structure comprising a north pole radially displaced from the axis and a south pole radially displaced from the axis and opposite to the north pole. The north pole and the south pole of the magnet extend radially into the direction of the axis at an axial end of the sensor assembly. The sensor assembly further comprises at least one sensor element sensitive to magnetic fields radially between the north pole and the south pole.

Sensor assembly for determining rotation about an axis and linear movement parallel to the axis

A method for determining a rotation angle of a magnet includes measuring a 3D magnetic field vector of a magnetic field generated by the magnet, wherein the 3D magnetic field vector describes at least a part of an ellipse in 3D space during a rotational movement of the magnet. The method further includes mapping the measured 3D magnetic field vector to a 2D vector based on a compensation mapping, wherein the compensation mapping is configured to map the ellipse in 3D space to a circle in 2D space. The method further includes determining the rotation angle of the magnet based on the 2D vector.
