摘要:
A position detector arrangement for detecting a position of a packaging material with magnetic marking comprises a sensor assembly comprising a plurality of magnetic sensor units each comprising an output providing an output signal. The magnetic sensor units are arranged in at least two sensor unit pairs, with the sensor units of each pair arranged with opposite sensitivity directions, and with the sensor units arranged to sense magnetic markings of the packaging material. A signal processing assembly is connected to the outputs of the magnetic sensors and comprises a combiner arranged to aggregate the output signals of the sensors to an aggregated signal; and a detector arranged to determine the position of the packaging material from the aggregated signal. Further, a method for detecting a position of a packaging material with magnetic markings is disclosed.

Disclosed is a magnetic sensor array which comprises at least one magnetic field-sensitive sensor element (3) and whose electrical properties can be modified in accordance with a magnetic field of a working magnet (5), said magnetic field being optionally influenced by a moved transmitter element. The inventive magnetic sensor array is poured in a plastic primary packaging at least together with the sensor element (3), optionally the working magnet (5; 5a) and additional components (15), while the primary packaging can be enveloped with a secondary packaging (9) in areas located away from the sensor head (2) encompassing the magnetic field-sensitive sensor element (3) in order to permanently fix the magnetic sensor array in a mechanical fashion in the sensor application, the electrical connections (6, 7) being established at the same time.

摘要:
Disclosed is a magnetic sensor array (1) comprising at least one magnetic field-sensitive sensor layer in an integrated multilayer GMR spin valve system, in which the magnetic field-sensitive sensor elements (10, 11, 12, 13) are interconnected so as to form a measuring bridge, the electrical resistance (R) thereof being modifiable in accordance with an external magnetic field. Each sensor element is formed by at least one largely linear measuring strip (10, 11, 12, 13) which extends perpendicular to the direction of the magnetic field (H) that is to be detected.
摘要:
The invention relates to an angular position sensor, wherein the sensor has a motor (130) for driving an output shaft (140) and a sensor element (165) for detecting changes of a magnetic field of a magnet (150) rotating in synchronization with the output shaft (140). A controller (110) compensates for outputs of the sensor element (150), when the output shaft (140) rotates clockwise and counterclockwise, using different multidimensional functions and controls the motor (130) so that the compensated rotation angle becomes a desired rotation angle.
摘要:
A magnetic sensor that is inexpensive and suppresses changes in offset voltage caused by wear. The magnetic sensor includes magnetoresistance elements having electrical resistances that change in accordance with magnetism changes. The magnetic sensor detects magnetism based on changes in the electrical resistances. The magnetoresistance elements are covered by a protective film. Part of the protective film is etched and eliminated to form a recess.
