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.
