H-MTD® connector systems
ensure efficient networking within vehicles

The development towards autonomous driving is in full swing. The prerequisite for this is powerful, reliable data transmission in vehicles. Differential connectors play an important role here - these are used to ensure the multitude of vehicle systems can be connected efficiently. The reliability of these connectors is guaranteed using new testing technology from INGUN, such as the radio-frequency test probe HFS-802 and the brand-new KS-802 mounting frame for six HF-802 H-MTD probes.

A modern car can contain up to 100 electronic control units (ECUs): from simple control programs to embedded platforms to complex, multifunctional real-time operating systems. The need for reliable high-speed data connectors especially for safety applications such as driver assistance systems (ADAS), which are the basis for autonomous driving, is increasing. Currently, level 3 of 5 has already been achieved as partially automated driving is now possible. On the journey to fully automated driving, the number and complexity of the systems in the vehicle - also for networking with the environment (V2X) using 5G (in future 6G) - will continue to increase.

Differential connector systems form the basis for this. In each case, two cables are routed in parallel to ensure interference and deviations in the transmission can be analytically compensated for. Differences cancel each other out, meaning digital data can be transmitted in high quality and at increasingly higher data rates - for cameras, infotainment, automotive Ethernet, and many other applications. One of the first differential automotive connector systems, the HSD series from Rosenberger, continues to provide connection of digital signals to the ECUs and has been tested using the HFS-819 test probe series from INGUN for years. However, this generation is gradually being replaced by more modern and more powerful systems.
