Steering wheel sensor


Our SENMSW series sensors are designed specifically for modern vehicle steering wheels, such as passenger cars and multi-purpose vehicles. The introduction of a new driving assistance system requires better performance testing equipment.

Our SENMSW series sensors perfectly meet the needs of modern automotive engineering. Reducing size and weight, providing higher dynamics and increased resolution without compromising steering wheel functionality (airbags) and control components. For optimal safety, the sensor has a high breaking torque. Our SENMSW series sensors are installed between the steering wheel and the steering shaft. For versatility, sensors can be equipped with interchangeable adapters for connecting to the steering shaft transmission.

Our SENMSW series sensors are equipped with switch reset torque and angle. The offset is stored and remains available after voltage loss or restart. Through the CAN bus, the output can be set to zero at any point. Calibration data is stored in sensor components, allowing users to replace sensor components as needed.
