D-Sub, D-Shaped Connectors - Accessories

D-sub, also known as D-shaped connectors, is a type of connector commonly used for computer cables, computer components, industrial equipment and consumer electronics. The term “D-sub” is short for “D-subminiature”, referring to the small size of the connectors, which are typically 2.8mm (0.100″) thick, 9.6mm (0.400″) wide, and less than 25mm (1.00″) long. D-sub connectors provide reliable electrical connections with superior noise suppression when compared to other types of connectors.

Application Field of 1201030003

The 1201030003 D-sub connector is one of the most common types of D-sub connectors. It features three pins, two of which are connected, while the third is isolated from the other two. This type of connector is typically used to connect a PC to a power outlet, and is the default connector type used for most PCs. It can also be used with some industrial equipment, audio and video equipment, and consumer electronics items.

Working Principle of 1201030003

When the 1201030003 D-sub connector is used, two of the three pins make contact, allowing power to pass from the PC to the outlet. The third, isolated pin ensures that the connector does not short circuit and reduces noise interference. The contact between the pins is made by pressure from two metal strips inside the connector. When the connector is inserted into a receptacle, the metal strips are compressed, creating a snug fit. This creates a reliable, stable connection capable of passing power smoothly.

Conclusion

The 1201030003 D-sub connector is a widely used connector type with a variety of applications. Its small size and robust construction make it ideal for a variety of applications, from PC connections to industrial equipment. Its ability to suppress noise and ensure a reliable connection make it a popular choice for many industries.
