1. Introduction

Automotive sensors are the perception core of vehicle electronic control systems, widely used in new energy vehicles, passenger cars and commercial vehicles. Sensor accessories and connectors undertake signal transmission, sealing protection and fixed assembly functions. Generic electronic connectors cannot meet the complex working conditions inside vehicles, including high temperature, vibration, humidity and chemical corrosion. Custom auto sensor accessories and connectors are tailor-made for automotive component manufacturers. Designed according to sensor structure, installation space and vehicle-level standards, these components ensure stable signal transmission, improve assembly efficiency and enhance the long-term reliability of finished automotive sensors.
