Benefits of technology
The method ensures a highly precise and leakproof sensor production, reducing the risk of moisture penetration and enhancing the sensor's resistance to weathering influences, while simplifying the fabrication process and maintaining precise sensor positioning.
Problems solved by technology
However, the problem basically arises here that part of the elements always rest on the edge of the mold, and therefore no complete seal is possible with the material at these locations because the elements cannot be encapsulated with the material at these locations.
Although, for example, by using a securing mechanism the measuring sensor can be secured in such a way that all the elements can be encapsulated completely with the material, the measuring sensor must be positioned in this securing mechanism, which, in particular owing to the rigidity of the cable, is only possible to a limited degree within sufficient tolerances.
In addition, the use of the measuring sensor in the securing mechanism requires additional fabrication steps, and also the securing mechanism cannot be completely encapsulated, as a result of which gaps remain through which the abovementioned moisture can penetrate and reach the measuring sensor and / or the data cable.

Embodiment Construction
[0031]In the figures, identical technical elements are provided with identical reference symbols and are described only once.
[0032]Reference is made to FIG. 1 which shows a schematic view of a vehicle 2 with a vehicle dynamics control system which is known per se. Details on this vehicle dynamics control system can be found, for example, in DE 102011080789 Al, which is incorporated by reference.
[0033]The vehicle 2 comprises a chassis 4 and four wheels 6. Each wheel 6 can be slowed down with respect to the chassis 4 by means of a brake 8 which is attached in a positionally fixed fashion to the chassis 4, in order to slow down the movement of the vehicle 2 on a road (not illustrated further).
[0034]In this context, it is possible that, in a manner known to a person skilled in the art, the wheels 6 of the vehicle 2 lose their grip and the vehicle 2 is moved away even from a trajectory which is predefined, for example, by means of a steering wheel (not shown further), as a result of unde...

Abstract
A method for producing a sensor which is equipped to detect a physical field as a function of a dimension to be measured using a measuring sensor and to emit an electrical output signal based on the detected physical field via a data cable, including:—placing the measuring sensor and the data cable on a mould defining the position of the measuring sensor and the data cable,—Coating the measuring sensor and the data cable positioned in the mould with a first material,—Removing the measuring sensor and data cable coated with the first material from the mould, and—Coating the measuring sensor and data cable removed from the mould and coated with the first material with a second material.
