VEMO Sensor, Wheel Speed V40-72-0344

The VEMO Sensor, Wheel Speed V40-72-0344 is a precision-engineered component designed to monitor the rotational speed of vehicle wheels. This sensor plays a pivotal role in modern automotive safety systems, particularly within the Anti-lock Braking System (ABS) and Electronic Stability Control (ESC). By providing real-time data on wheel velocity, it enables the vehicle’s control modules to detect and mitigate wheel lock-up during braking, ensuring optimal traction and stability.

Key Functionalities

• Wheel Speed Detection: Measures the rotational speed of each wheel with high accuracy, allowing for precise braking modulation.
• ABS Integration: Works seamlessly with the vehicle’s ABS module to prevent wheel lock-up, enhancing braking performance on slippery surfaces.
• ESC Support: Supplies critical data to Electronic Stability Control systems, aiding in the detection of understeer or oversteer conditions.
• Signal Output: Generates a standardized pulse signal that is interpreted by the vehicle’s electronic control unit (ECU).

Technical Specifications

Compatibility and Applications

The VEMO V40-72-0344 sensor is engineered to fit a wide range of front-wheel and rear-wheel configurations across multiple vehicle platforms. It has been validated for use in models such as:
