MIL-DTL-83513 DB9 Serial Port Micro-D Connectors

Micro-D Connectors are sub-miniature panel-type connectors with polarized shells. This type of connector use pin & socket machined contacts that are reliable for critical applications. With their versatile design, these high-performance connectors are used in a variety of applications where weight & size are critical factors. An example would be the blue port on the backside of the old motherboard which was used to connect serial devices.

These connectors are ideally suited for applications requiring extremely small, lightweight, and ruggedized solutions with higher density contact configurations.

MIL-DTL-83513 Serial Port Connector Description

MIL-DTL-83513 series connectors are available in many different pin configurations ranging from 9 to 100 and can be used for military and aviation. But for the sake of simplicity, we are going to take the example of the DB9 port. Both Serial and Parallel Ports have been used since the beginning of the PC era and they mostly remained unchanged over the years. The RS-232 protocol was first introduced in the 60s that defines how the data is transferred bit by bit from a data terminal equipment such as a computer to an external terminal or any data communication equipment like mode or any other devices. The RS-232 is the common standard used in serial ports. It defines the electrical properties and the timing of signals, as well as the interpretation of signals. One of the original uses of the serial port was to use to transfer data between two PCs. Other than that, it was used in old modems and mouse.
