The Bosch Motorsport Steering Angle Sensor (LWS) is a professional-grade, high-speed CAN bus steering position sensor designed for motorsport applications where precise vehicle dynamics data is critical. Whether you're integrating a Bosch Motorsport ABS M5 Kit, MoTeC ECU, Bosch Motorsport ECU, or professional data acquisition system, the LWS delivers exceptionally accurate steering wheel angle and steering rate information at 100 Hz (10 ms) over 500 kbit/s CAN.
Unlike basic potentiometer-based steering sensors, the Bosch LWS utilizes Giant Magneto Resistive (GMR) technology to provide absolute steering angle measurement without mechanical wear. The result is reliable, repeatable steering position data capable of surviving the harsh environments found in endurance racing, GT3, Time Attack, rally, off-road, and custom performance builds.
