Introduction to D-Sub Connectors

D-Sub Connectors, also referred to as 9-pin connectors, are a type of electrical connector used in many types of electronics and computer-related applications. These connectors are popular due to their relatively low cost and versatility. They are commonly used in applications such as communication ports, serial ports, USB ports, and video ports.

The History of D-Sub Connectors

The D-Sub connector was developed in the late 1960s by U.S. manufacturer Amphenol. The first D-Sub connector was designed to connect two leads for a telephone line, and was patented in 1969 by Amphenol engineers Robert Schenck and James Sanders. Initially, the connectors were produced in 10 to 120-pin versions for use in telephone and communications applications, and later scaled up to larger sizes for use in computer applications.
