1100 03 004 MERCEDES BENZ Sensor Ring, ABS Sensor

The technical role of the sensor ring within the ABS system is critical for maintaining precise wheel speed monitoring and ensuring stable braking performance. This component serves as the interface for the ABS sensor, providing a consistent signal pattern to the electronic control unit. Manufactured with high-strength components, it is designed to withstand the rigorous mechanical stresses typical of heavy commercial vehicle operations.

1100 03 004 is the OE-equivalent of the MERCEDES BENZ 975 334 04 15 sensor ring used in MERCEDES BENZ vehicles. This part features an inside diameter (d) of 144 mm, an outside diameter (D) of 148/177 mm, and a height of 5/12 mm with 80 holes. It is specifically developed to meet the exact fitment requirements of the brake system sensors in heavy-duty applications.

Workshop technicians should ensure that the mounting surface is clean and free from debris before installation to prevent signal interference. Regular inspection of the sensor ring and surrounding brake components is recommended during routine maintenance to ensure the integrity of the ABS system. Proper alignment during assembly is essential for long-term durability and accurate sensor readings.

This product is engineered to maintain precise tolerances, ensuring that the number of holes and diameter specifications match original equipment standards. This precision helps prevent premature wear and maintains the reliability of the vehicle's anti-lock braking functionality.
