Steering Angle Sensor, Design

Body
Digital sensor with 9 light-emitting diodes (a) for photoelectric barrier measurement. The steering angle sensor consists of 2 microprocessors forming a single unit together with one signal ring. The signal ring accommodates the 9 light-emitting diodes (a) at equal intervals. These are located in a photoelectric barrier duct which is traversed by 8 blades (b) of various lengths. The photoelectric barriers are located in the upper part of the contact spiral (A45) and the two components must be assembled (clipped together) to form the complete functional unit of the optical steering angle sensor (N49).
