What is a D-Sub Connector?

A D-Sub Connector is a type of electrical connector that has two rows of pins as well as an array of sockets. The pins are typically arranged in an inverted ‘V’ shape, while the sockets are placed in an ‘X’ formation. They are usually referred to as ‘D-Subs’ and they are commonly used for data transfer and signal transmission.

Application Fields

D-Sub Connectors are extremely versatile, and have a wide range of uses across many different sectors. These include:

• Computer Applications – D-Sub Connectors are commonly used in a variety of computers and computer components such as modems, graphics cards, printers, storage devices, and network switches.
• Audio/Video – D-Subs are used in a variety of audio and video equipment, including televisions, DVD players, and audio systems.
• Industrial – D-Subs are used in various industrial and scientific applications. Examples include measuring devices, robotics, and industrial controls.
• Medical – In the medical field, D-Subs are often used to connect various monitoring and diagnostic equipment to medical systems.

DBM21W1P1AFNA190 Working Principle

The DB21W1P1AFNA190 is a D-Sub Connector that is commonly used in computer applications. This particular model has 21 total pins, with a mix of male and female connections. It is used to connect two pieces of equipment such as a computer and a monitor or a printer and a computer. The pins on the DB21W1P1AFNA190 are arranged in an inverted ‘V’ pattern that allows for a high contact density.The DB21W1P1AFNA190 is designed with a special coating that helps protect the pins from corrosion and other forms of damage. Additionally, it comes with a variety of locking mechanisms and other features that make it more secure. For example, the DB21W1P1AFNA190 is designed with a “floating” mechanism that prevents the pins from fully penetrating the female connection.The DB21W1P1AFNA190 also utilizes a spring-loaded system that helps ensure the connector stays locked in place. This is especially useful when it is used in applications where vibration or shock are present. Additionally, the DB21W1P1AFNA190 is designed with a dust-proof seal that helps keep out contaminants and dust.

Conclusion

D-Sub Connectors, such as the DB21W1P1AFNA190, are highly versatile and have a wide range of uses in many different sectors. They are designed with various features and locking mechanisms that make them more secure and reliable. Additionally, their inverted ‘V’ shape and high contact density makes them a popular choice for computer applications.
