The Body Height Sensor is a critical component in modern automotive suspension and chassis control systems, designed to monitor the vertical position of the vehicle body relative to its chassis. It plays a vital role in active suspension systems, adaptive damping controls, and automatic headlight leveling applications—ensuring optimal ride comfort, handling stability, and visibility under varying load conditions and road surfaces. By converting mechanical displacement into an electrical signal, this sensor enables real-time feedback to the vehicle’s Electronic Control Unit (ECU), allowing dynamic adjustment of suspension stiffness, damping force, or air pressure in air-sprung systems
This sensor employs advanced Hall-effect sensing technology, which provides high accuracy, excellent long-term stability, and strong resistance to electromagnetic interference (EMI). The integrated magnetic field detection allows precise measurement of angular displacement, with high angular resolution suitable for both small and large range movements. It supports multiple output formats—including analog voltage, PWM (Pulse Width Modulation), and PSI5 digital interface—enabling seamless integration with various controller architectures across different vehicle platforms.
The sensor features a modular design with standardized mounting brackets and linkages, allowing easy adaptation to different suspension geometries and vehicle types. Its self-lubricating spherical joint ensures smooth operation and long service life, even under continuous vibration and harsh environmental conditions. The housing is engineered to meet stringent waterproof and dustproof requirements, ensuring reliable performance in all weather conditions—from rain and snow to mud and road salt exposure.
