Steering Angle Sensor

 

        The Steering Angle Sensor (SAS) is used to measure the angle of rotation of the steering wheel when the car is turning.This is a non-contact multi-rotation angle sensor and can detect the absolute steering wheel angle. The sensor development process complies with the functional safety specification standard ISO26262.

 

Application

•  Adaptive Front-lighting System(AFS)
•  Electrical Stability Program (ESP)
•  Electrical Power System (EPS)
•  Advanced Driver Assistance Systems (ADAS)
