Features and Benefits

As the number and variety of devices in vehicles increases, additional wiring requirements create more complexity, higher costs and the inefficiencies of mixed-protocol networks that require substantial validation and expensive gateways. The increasing prevalence of zonal architecture and SDV platforms also calls for high-performance solutions that are compact, rugged and reliable.

Multi-drop—or daisy-chain—10BASE-T1S Ethernet networks support zonal architecture and complex vehicle networks by simplifying wiring harness design and minimizing weight and cost. Miniaturized interconnect solutions designed for harsh automotive environments improve reliability, enable greater vehicle functionality and simplify increasingly complex wiring architectures.

The HSAutoLink E Cable Assembly is a purpose-built, multi-drop solution that can support lightweight 28 AWG cable to reduce wiring weight and cost, eliminate protocol gateways and accelerate system integration for future-proof wiring. The miniaturized two-circuit connector soldered terminal interface and 1Gbps data rate improve performance and enable scalability as manufacturers transition from legacy networks to unified Ethernet-based multi-drop architectures.

Simplify Vehicle Network Wiring

Supporting zonal architecture, edge-node applications and scalability, the HSAutoLink E system connects up to eight nodes on a single cable assembly, reducing wiring complexity for future-ready architecture. The short-capable, soldered termination enhances reliability and enables system operation even in the event of single-point node failures.

Reduce Weight, Space and System Cost

The compact two-circuit HSAutoLink E connector and 28 AWG jacketed-unshielded twisted pair (JUTP) or unshielded twisted pair (UTP) cable help reduce vehicle weight and costs while improving packaging flexibility and simplifying wiring harness design. The multi-drop interconnect system shortens cable lengths and reduces connector counts, accelerating manufacturing and minimizing space requirements.
