1. Overview

Rectangular cable assemblies are engineered interconnect solutions featuring rectangular-shaped connectors and integrated cables. They enable reliable signal, data, and power transmission in electronic systems. These assemblies are critical in modern technology for their compact design, high-density connectivity, and robust performance in demanding environments.
