Abstract
A measuring element (26) for detecting the movement of a vehicle to be monitored and an electrical circuit (35) for evaluating the measuring signals of the measuring sensor (26) are disposed in a housing (10) of a rotation rate sensor. The circuit (35) is connected with the measuring element (26) with the aid of a flexible printed circuit board (36). The printed circuit board (36) is bent 90 degrees in the area of the measuring element (26) in order to make possible a compact and space-saving construction in the housing (10, 11, 12). The printed circuit board (36) has a cutout (39) and two strips (40, 41) extending parallel with the cutout (39) in the bending area in order to make simple bending possible. It is furthermore possible in a simple way to insert a temperature sensor (45) into the one end (38) of the printed circuit board (36) in order to make possible a simple compensation of the deviation of the temperature.
