Abstract: A sensor for a magnetic measuring device for detecting a rotational or translational movement of a body includes a permanent magnet which is connected to the body for conjoint rotation and which moves with the body. The sensor is fastened to a body by a method, and the sensor can be used in a magnetic measuring device for contactlessly detecting a rotational movement of a body. Plastic-bonded permanent magnet material is injection-molded onto the body, acting as an extension thereof, and forms a free end of the body acting as a permanent magnet.

Abstract: A method for producing a measurement value transmitter for a sensor device includes providing a magnetic body, providing a coil configured to be supplied with a current, and shaping the coil into a helical winding with an internal diameter that is greater than an outer contour of the magnetic body. The winding is shaped such that the pitch of the winding changes at least in some sections when viewed along the longitudinal extension of the winding. The method further includes arranging the magnetic body within the coil, in particular coaxially to the coil, and supplying the coil with a current so as to magnetize the magnetic body in order to produce the measurement value transmitter.

Abstract: A displacement sensor has a magnetic measuring transducer and at least two sensor units, which are arranged at different positions spaced from each other, the measuring transducer being slidably mounted relative to the sensor units. The measuring transducer is magnetized such that it has a magnetic field which rotates at least partially about an axis of rotation along the measuring transducer, and the axis of rotation of the magnetic field runs parallel to the sliding direction of the measuring transducer. The sensor units are designed to each sense two magnetic measured variables proportionally to the magnetic field strength, both measured variables being sensed by both sensor units.

Abstract: An angle sensor for determining a rotation angle of a rotatable body, such as a steering column in a motor vehicle, includes a gear wheel. The orientation of a magnetic field generated by the gearwheel is configured to be detected by a magnetic field sensor. The gear wheel is comprised of a magnetisable material, such as hard ferrite, into which a magnetization is introduced. The gear wheel is stronger in a central region than in an edge region in which the teeth are arranged. In order to weakly magnetize the edge region, which minimizes a negative influence of the teeth on the homogeneity of the generated magnetic field, the front face of the gear wheel is configured to be magnetized. The magnetization process advantageously takes place at the same time as an injection moulding process to form the gearwheel. A method is implemented to produce the gear wheel.

A magnetic measuring arrangement configured to detect motion of the object includes at least one permanent magnet and at least one sensor element configured to detect the magnetic variable.
