1. Overview

Rectangular connectors - adapters are electromechanical devices that bridge incompatible interfaces between systems or components. They enable signal, power, or data transmission across dissimilar connector standards while maintaining electrical integrity. These adapters are critical in modern electronics for ensuring interoperability in industrial automation, telecommunications, and consumer devices. Their modular design supports rapid system integration and legacy system upgrades.
