Introduction

D-Sub Connectors, or DB Connectors as they are commonly called, are used to connect two electronic devices such as computers, workstations, printers, and other peripherals. They were developed in the mid-80s to provide a more reliable way to ensure electrical, mechanical and data transfer connections between digital devices.

Types

D-Sub connectors come in a variety of sizes and shapes. The most common are the 15-pin, 25-pin, 37-pin, and 50-pin. The 15-pin D-Sub is usually found in the computing and multimedia industry as the input/output connectors for video cards, sound cards, and modems. The 25-pin, on the other hand, is primarily used to connect printer ports. The 37-pin and 50-pin D-Sub connectors are used in the industrial and instrumentation field, mostly to connect serial and parallel ports.

Materials

D-Sub connectors are made up of three main components; the shell, pins, and contacts. The shell consists of a metal plate with threaded lugs for attaching the pins and contacts. The pins are metal tubes that make up the external part of the connection. The contacts are small metal tabs with wires that connect the pins to the terminals. These components are usually made from nickel-plated brass or aluminum alloy.
