A housing with an open receiving chamber which has a circumferential edge in the form of a creepage barrier at an open upper face is disclosed. The receiving chamber is filled with a casting compound, and the hardened casting compound forms a concave surface relative to the circumferential edge at the open upper face. A sensor is also disclosed that includes such a housing. In addition, a method for casting an open receiving chamber of such a housing is disclosed. The open receiving chamber has an opening at one end leading to an enclosed interior adjoining the open receiving chamber. The enclosed interior is filled with the casting compound, and the open upper face of the receiving chamber has a varying height where the upper face transitions into the enclosed interior. The circumferential edge has an outwardly descending inclination and a continuous curvature formed by tangential transitions in order to overcome the height difference, and the circumferential edge allows the receiving chamber to be temporarily overfilled, thereby forming a stable convex casting compound surface, during the casting process.

An anti-lock sensor ring may have a flattened exciting portion having a retention mechanism projecting from a ring radial edge. The retention mechanism may have cantilever spring retention clips elastically deformable to snap on a disc brake band retention seat. The mechanism may also have a cantilever support portion disposed side by side to and spaced apart from the cantilever spring retention clips. Each of the cantilever spring retention clips may have a retention surface and the cantilever support portion with a support surface. When the anti-lock sensor ring is dismounted from a disc brake band, the plane defined by the retention surface and the plane defined by the support surface are facing each other in order to create opposing gripping elements.

It is provided that the housed semiconductor sensor element is glued onto a mounting surface of the holder body using an adhesive that differs from the enveloping material, and that the adhesive is situated in a receiving space between the mounting surface and a bottom side of the housed semiconductor sensor element that is facing the mounting surface.

According to an example embodiment, an apparatus for wind speed measurement is provided, the apparatus comprising: a pressure sensor arranged to provide a pressure sensor signal that is descriptive of an instantaneous air pressure; a wind shield arranged to prevent a direct airflow from the environment of the apparatus to the pressure sensor; and a processing unit for deriving, based on the pressure sensor signal, one or more wind speed characteristics that are descriptive of the wind speed at a predefined reference measurement height.

A speed sensor for measuring a speed of an object moving relative to the speed sensor, including: a speed sensor housing for providing sliding and/or frictional and/or positively locking insertion into a fixed receptacle, wherein the speed sensor housing houses an injection molded part which is made of plastic and into which at least part of a speed sensor element is injected; wherein the injection molded part has at least one outer recess, on its outer circumferential surface facing an inner face of a wall of the speed sensor housing, wherein an empty outer chamber is formed between each boundary surface of an outer recess and the inner face of the wall of the speed sensor housing, and/or wherein at least one inner recess, which forms an empty inner chamber, is formed inside the injection molded part. Also described are a related driver assistance system and a motor vehicle.

A system for monitoring the axial position of a rotating shaft includes a phonic wheel mounted coaxially to the shaft for rotation with a circumferential row of teeth. The system includes a sensor configured to detect the passage of the teeth by generating an alternating measurement signal. First and second portions of the teeth alternate around the row and contribute respective first and second components to the alternating measurement signal. The first portion of teeth vary in height in an axial direction of the wheel such that the relative height of the first and second portions varies with axial distance across the phonic wheel, and the sensor is positioned relative to the phonic wheel such that axial displacement of the shaft causes the signal to vary the first component's amplitude relative to the second component's amplitude due to the height variation, to monitor the axial position of the shaft.
