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.
