Steering Angle Sensor Absolute
SASA
Steering Wheel Position
The SASA sensor detects the absolute position and speed of the steering wheel. The sensor can be used in electro-hydraulic steering systems using Danfoss OSPE, EH or EHPS steering valves with programmable controllers.
The use of SASA sensor is relevant e.g. for variable steering ratio and closed loop set-ups where steering wheel position and steering angle have to match.
SASA is based on a noncontact inductive principle giving a very high resolution. The sensor features a robust design and resist e.g. electro-magnetic radiation. The output is a CAN signal, which makes it easy to interface to advanced vehicle controllers.
The steering wheel shaft turns the rotor of the SASA sensor, and the sensor is simply mounted between steering unit and steering column.
Features
•High resolution <0.1°
•Output CAN signal
•High safety, “fail silent” concept
•Flanged in between steering unit and column
•Compact design
