Picture of Linear displacement sensor SASA

Linear displacement sensor SASA

  • Non-contact inductive principle, giving very high resolution < 0.1°
  • Robust design, resistant to electro-magnetic radiation
  • CAN output signal for easy interfacing with advanced vehicle controllers
  • Mounted between the steering unit and column, contributing to system compactness
  • Compact design
  • High safety
  • SASAIIC: “fail silent” concept
  • SASAIID: two output messages concept and PLUS+1® compliant

The SASA (Steering Angle Sensor Absolute) 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 resists e.g. electromagnetic 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 the steering unit and steering column.
