Abstract

A level sensor for a motor vehicle includes a housing, a rotor rotatably mounted on the housing, and a printed circuit board enclosed in the housing. The printed circuit board includes at least one stator and is connected to a plug which can be attached to an opening in the housing, and seals the opening thereby. The printed circuit board and electronic components are readily and permanently protected against environmental influences. Housing has a chamber for accommodating the printed circuit board, and the opening is allocated to the chamber. The chamber is closed on all sides, with the exception of the opening. The printed circuit board can be inserted in the chamber in the manner of a drawer and can be positioned therein.
