Function and role in the safety system

The crash impact sensor responsible for pedestrian protection in the Mercedes CLA C117 model acts as an input element for passive safety controllers. It registers characteristic accelerations and deformations in the collision zone and then transmits a signal to the control modules, which can trigger appropriate protective procedures. A properly functioning sensor is crucial for maintaining the system's operating logic as designed by the manufacturer.

A solution of this type is particularly important in modern designs, where pedestrian protection systems work with other electronic vehicle systems. A functional crash impact sensor allows for maintaining the integrity of the entire safety chain, from event detection to the response of actuators.

Construction and integration with vehicle electronics

The offered element comes from the family of Mercedes electronic components and has been designed to work with factory vehicle controllers. The sensor's construction is optimized for installation in the location provided by the manufacturer, which facilitates maintaining the correct geometry and measurement directionality. As a result, the signal from the sensor is interpreted in accordance with the assumptions of the engineers responsible for the safety system.

As a part from the Lidar and radar sensors group, the component is adapted to work in an environment with increased requirements regarding resistance to interference and parameter stability. Proper shielding and electrical matching to the vehicle's wiring harness facilitate correct communication with other modules.

Benefits of using an original used sensor

Choosing an original, used crash impact sensor for pedestrian protection allows for maintaining the factory characteristics of the safety system while optimizing repair costs. This type of component is designed for close cooperation with a specific vehicle platform, which translates into:

• maintaining the system's activation logic as intended by the manufacturer,
• proper cooperation with existing controllers and the electrical wiring harness,
• consistency of parameters with other elements of the safety system.
