Abstract
The invention is based on a sensor device having at least one transmitter unit situated inside a sensor body, a receiver unit associated with the transmitter unit and situated inside the sensor body, and an end face that is situated between the transmitter unit and receiver unit and constitutes a boundary surface of the sensor body. According to a first aspect of the invention, it is possible to achieve a compact embodiment with low requirements for assembly-related production tolerances if the transmitter unit and/or the receiver unit is/are comprised of an injection molded part with an incorporated radiation transmitter and/or radiation receiver. According to another aspect of the invention, a radiation transmitted from the transmitter unit to the receiver unit essentially travels in a beam path outside the sensor body. The invention also relates to a use of a sensor device and a vehicle light.
