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.
