D-Sub (VGA) Connector|Classic Analog Video Transmission Interface

Product Overview

D-Sub (D-Subminiature) is a widely used interface for transmitting analog video signals. The most representative application is VGA (Video Graphics Array), commonly found in computer graphics cards, monitors, and projectors. Characterized by its D-shaped shell and multi-pin design, the connector provides a stable mechanical structure and reliable contact performance.
