D-Sub, D-Shaped Connectors - Housings are widely used for the applications requiring high-performance and reliable connections such as medical, networking and embedded systems, industrial, automotive, military and aerospace applications, and consumer applications.

D-Sub connectors are rectangular high-density connectors that come in various sizes, and are typically comprised of two pieces - a male connector housing with built-in contacts, and a female connector housing with the corresponding contacts.

The female part of the connector housing has an opening which is shaped like a D, with the male contact attached to the female part. This D shape makes the connection very secure, as the male part is physically held in the housing when the connection is made.

To make the connection, the male part must be firmly pushed into the female part until a click is heard, indicating that the connection has been made. The male part is then kept securely within the female part and becomes a permanent connection.

The contacts used vary depending on the application, and are selected based on their resistance and insulation rating, as well as the type of current they are to carry. The contacts may be crimp terminals, PC tails or solder terminals. The contacts are usually plated with gold or silver to maximize the electrical performance and signal integrity.

D-sub connectors come in both standard and custom configurations, and can be used in a variety of applications. These include data, video, audio, power, serial, control and communication. D-sub connectors are also commonly used in medical imaging, industrial control, automotive electronics and telecom applications.

The working principle of D-Sub connectors is relatively simple. The connection between the contacts is made by pushing the male contact into the female part. The male part is held securely within the female part and forms a permanent connection. The contacts are usually plated with gold or silver to maximize the electrical performance and signal integrity.

The great advantage of D-sub connectors is their high density, which allows for more compact installations than traditional connectors. Furthermore, they are reliable, durable and easy to use, making them an ideal choice for many applications.
