Abstract
The invention relates to a sensor device (1) which comprises a circuit board (50) and at least one sensor (52) arranged on the circuit board (50). Further, the sensor device (1) comprises a housing (20) wherein the housing (20) comprises at least a first opening (30). The circuit board (50) comprises a marking (40), wherein the marking (40) codes information, and wherein the at least one first opening (30) is configured and arranged such that it leaves the marking (40) uncovered by the housing (20) such that the marking (40) is visible from outside of the housing (20) through the at least one first opening (30).
Claims14
A sensor device (1), comprising:
- a printed circuit board (50),
- at least one sensor (52) arranged on the printed circuit board (50),
- a housing (20) covering at least a part of the printed circuit board (50), characterized in that
- the printed circuit board comprises a marking (40) coding information, wherein the marking (40) occupies a marking area (A) on a surface (50a) of the printed circuit board (50), and wherein the housing (20) comprises at least a first opening (30) designed such that the marking (40) is visible from an outside of the housing (20) through the at least one first opening (30), and wherein the at least one first opening (30) extends over an area (B) that is smaller than ten times the marking area (A) or that is equal to ten times the marking area (A).
A method for producing a sensor device (1) comprising the steps of:
- providing a printed circuit board (50) comprising a marking (40) that codes an information,
- arranging at least one sensor (52) on the printed circuit board (50), and
- covering at least a part of the printed circuit board with a housing (20) comprising at least a first opening (30) such that the marking (40) is visible from an outside of the housing (20) through the at least one first opening (30).
