D-Sub connectors (also known as D-shaped connectors) are extremely common and reliable connectors used in many different types of devices. They are available in a variety of configurations and styles to meet various applications and can be used for a variety of post-application and interconnection solutions. They are also available in two different contact arrangements: 9X and 11X.

The 9X contact arrangement has 9 contacts arranged in two rows. The first row is composed of 8 contacts (6 or 7 in some cases) and the second row contains 1 contact. This is often referred to as the "standard" D-Sub configuration. The 11X contact arrangement adds two extra contacts to the first row of contacts in the 9X contact arrangement, creating the 11X configuration.

Backshells, hoods, and housings are some of the most common parts of D-Sub connectors. Backshells are designed for robust protection and ensure that the connector is properly sealed from the outside. They also provide strain relief for the cable that is attached to the D-Sub connector which helps to protect it from stress or other damaging forces. They come in various sizes and are used with a wide range of D-Sub connectors. Hoods are similar to backshells in that they help to protect the connector and can also provide strain relief. They are available in both metal and plastic varieties.

The working principle of a D-Sub connector is quite simple. When the connector is plugged into an associated device, all of the contacts inside the connector make contact with corresponding contacts inside the associated device, thus establishing an electrical signal path. This signal path allows the signal to travel from the device to the connector and vice versa. The construction of a D-Sub connector is designed to ensure that the contacts remain securely in contact with the device while the connector is being plugged in and unplugged.

The applications of D-Sub connectors and parts are vast and can be used in various industries such as automotive, aerospace, audio/visual, instrumentation, industrial automation, and telecommunications. As mentioned, they can be used for post-application and interconnection solutions, as well as for a vast array of other useful purposes. For example, D-Subs are often used in computer equipment such as printers, modems, and LCD displays, as well as in medical imaging equipment.

The D-Sub connector is a reliable solution for many different types of devices and applications. The 9X and 11X contact arrangements provide the versatility that is required for many different types of applications. Backshells, hoods, and housings provide the necessary protection and strain relief that is required for these connectors, and the working principle is quite straightforward. With the vast array of applications and its reliable construction, the D-Sub connector is an invaluable tool for many industries.
