As automotive technology advances toward fully autonomous driving, the limitations of traditional flat and domain-based electronic architectures are becoming increasingly apparent. This whitepaper, crafted by Molex subject matter experts, explores how connector miniaturization plays a pivotal role in enabling next-generation automotive system designs, specifically within zonal architecture frameworks that promise improved scalability, reduced cabling complexity, and enhanced vehicle performance.

Zonal architectures represent a transformative shift, where localized gateways replace centralized domain controllers to optimize data flow, reduce wire harness weight, and support the growing demands of ADAS (Advanced Driver Assistance Systems). To realize the full potential of this architecture, high-performance miniature connectors are essential. These connectors must offer high data transmission rates, withstand extreme automotive environments, and support high-volume, automated assembly—all while maintaining signal integrity and mechanical reliability.

Molex addresses these needs with a robust portfolio of interconnect solutions, including 0.50 mm high-speed floating board-to-board connectors, DuraClik™ wire-to-board systems, SlimStack™ FPC-to-board and board-to-board connectors, and Easy-On FFC/FPC products. Each is engineered to perform under high temperatures, shock, and vibration, with advanced features such as wide mating alignment, retention forces of up to 50N, and blind-mating capabilities that enhance assembly efficiency and reliability.
