Abstract
The invention relates to an angle sensor which is only protected by an encasement body without having a surrounding protective housing.
Claims33
An angle sensor (2), said sensor comprising:
- a magnetically sensitive face portion, which operates according to the Hall-principle or according to the magneto resistive principle, comprising a sensor element (5) proximal to its front face;
- a carrier board (9) used for mounting to a vicinity;
- an electric circuit, mounted to a circuit board (1), completely enclosed by a hardened encasement body;
- the encasement body mounted to the circuit board (1) in a form-locked manner and through adhesion;
- and wherein said carrier board simultaneously forms said circuit board to form a combined carrier board and circuit board and wherein said combined carrier board and circuit board is made from the group consisting of:
- plastic, fiber reinforced plastic, glass fiber reinforced epoxy (GRP), and partially comprises a metal coating which is electrically conductive;
- the metal coating comprises all portions of the carrier board and circuit board (9/1) which are not covered by said encasement body (3), including all narrow sides (9c) of said carrier board (9/1);
- and
- the metal coating is only provided on a surface portion of an upper side (9a), which is covered by said encasement body (3), where the coating is required for an electrical conductor path.
