SKF Electronic Steering Input Unit

Electronic steering input unit

The SKF Electronic Steering Input Unit is a mechatronic solution with integrated Electronic Control Unit (ECU), embedded software and CAN bus interface, which can replace the traditional steering column offering a robust steering input function to be fitted in both electro-hydraulic and electro-mechanic steer-by-wire systems. 

The solution translates the steering wheel's rotational movement into safe digital information on the CAN bus, offering a resistive steering feedback with redundant control. Engineered to withstand severe operating conditions and tested to fulfill the severe steering input requirements for marine and off-highway segments, these units have passed an extensive set of mechanical, environmental and electrical tests.


  • Redundant position signal for steering wheel
  • Controllable resistive steering feedback with redundant command
  • Compact design
  • Contactless sensors
