A D-sub connector, also known as a D-subminiature connector or simply D-sub, is a type of electrical connector that is widely used in a variety of applications, including computers, telecommunications, and industrial machinery. The D-sub connector is named after its "D-shaped" housing, which provides mechanical stability and protection for the pins inside.
In this article, we will take a closer look at D-sub connectors, their types, applications, and advantages.
Types of D-Sub Connectors
There are several types of D-sub connectors, each with a different number of pins and configurations. The most common types include:
- 1. DB-9: This type of connector has nine pins arranged in two rows. It is commonly used in serial port applications, such as connecting a computer to a modem or a printer.
- 2. DB-15: The DB-15 connector has 15 pins arranged in three rows. It is often used for video applications, such as connecting a computer to a monitor or a projector.
- 3. DB-25: The DB-25 connector has 25 pins arranged in two rows. It is commonly used for parallel port applications, such as connecting a printer to a computer.
- 4. HD-15: The HD-15 connector, also known as a VGA connector, has 15 pins arranged in three rows. It is commonly used for video applications, such as connecting a computer to a monitor or a TV.
- 5. DE-9: The DE-9 connector, also known as a D-subminiature E connector, has nine pins arranged in two rows. It is commonly used in industrial applications, such as connecting sensors and control devices.
