What Is a D-Sub Connector?
The D-sub Connector is one of the standards for connecting computers to peripheral devices.
The name "D-sub Connectors" comes from the shielding portion of the D-sub Connectors, shaped like the letter D, to suppress interference from external electromagnetic waves.
There are more than 20 types of D-sub connectors in the lineup, with a significant variation in the number of pins (number of signal lines) and different sizes. The size and number of pins denote the names of these types.
Uses of D-Sub Connectors
The D-sub Connector is an old standard that was once widely used. Although its role has now been replaced by USB, it is still used for video output to displays and other devices.
The DE-15 connector with three rows of five pins is well-known for output to displays and is also called a VGA (video graphics array) terminal. Although digital connections such as HDMI, DVI, and DisplayPort are becoming mainstream today, the DE-15 connector is still used because it is highly versatile.
Principle of D-Sub Connectors
The D-sub connectors consist of a basic structure of contacts and housing and components called shells and eyelets. The contact, also called a terminal, is the metal part used to conduct electricity. The housing is the part into which the contacts are incorporated and is made of insulating material.
D-sub Connectors have different numbers of contacts (number of pins) depending on the application. The most famous is the 15-pin DE-15, which we see almost daily. Other commonly used RS-232C connectors for connecting industrial machinery and other devices use the 9- or 25-pin DE-9 or DB-25.
In the D-sub connectors, every contact is assigned to a different signal type. For example, in the case of VGA output, each contact has a specific role: the first connector is for red, the second for green, and the third for blue video output.
