Abstract: An inductive sensor device for detecting a reciprocating movement of an object includes an oscillator circuit and a processing unit. The oscillator circuit has a sensing coil configured for inducing eddy currents in the object. The processing unit is configured to count a plurality of oscillations of the oscillator circuit detected in a plurality of sampling periods, compare the oscillations with a predetermined mean value of oscillations, and determine both a speed and a position of the object based on a comparison of the oscillations with the predetermined mean value of oscillations.
Abstract: A ferrite core coil device as a sensing element for a sensor device determining a rotational speed of a metallic rotatable object includes a coil having a first sector and a second sector and a ferrite core holding the coil. The ferrite core has a shape of a disk lacking a disk sector and defined by a contour of the disk and a chord of the disk. The chord forms a bending edge of the ferrite core. The first sector of the coil is not arranged on a bed of the ferrite core and the second sector of the coil is arranged on the bed. The first sector is bent around the bending edge at a bending angle with respect to the second sector.

Abstract: A method for manufacturing a sensor module having a passive electrical component comprises punching a plurality of holes in a first green sheet of a plurality of green sheets, and forming a plurality of channels and a plurality of passageways in a second green sheet of the plurality of green sheets by using a laser on the second green sheet. A metallization paste is printed in the plurality of holes, the plurality of channels, and the plurality of passageways, and the first green sheet and the second green sheet are dried with the metallization paste. The method further comprises aligning, stacking, laminating, and sintering the plurality of green sheets together to create a sintered tile, and separating a plurality of coils of the sintered tile in order to obtain the sensor module.
