D-sub (D-shaped connectors) accessories belong to the family of electrical connectors made with parallel rows of dip contacts in a D-shaped shell. The D110280 connector is specifically designed with 28 parallel contacts that transmit both digital and analog signals and is mainly used for machine control, audio, and video applications. This article will explore the application field and working principle of the D110280 connector.

Application Field

Although the D110280 has a wide range of applications, it’s mainly used in high-speed serial digital and analog communication. Therefore, its connections involve mostly specialized equipment and automation. It is also often used for machine control, audio, and video applications. The D110280’s electronic connections provide superior signal transmission and dynamic range, with good resistance to electromagnetic interference.

D110280 connectors are commonly used in the aerospace, automotive, and telecommunications industries. It is also used in medical imaging systems, broadcast and professional audio systems, and lighting control systems.

Working Principle

The D110280 connector has 28 contacts. It is divided into even and odd sides, each with 14 pins. Each pin consists of a shell and a contact register. The contact registers are constructed of metal with a strike surface called a datum. When the connector is plugged in, the datums strike each other and establish a connection. The connecting pins are divided into even and odd sides according to their difference in structure. Even and odd sides will fit together in only one direction.

D110280 connectors have their own unique polarizing key and groove. This key and groove construction have precisely measured sections, which prevent uneven coupling. The connector interface offers good mechanical stability and a reliable contact due to its electrical and electronic design features. For instance, the contact regions are made of gold or Nickel-plated copper, the insulation between contacts is designed for low capacitive crosstalk, and the connector also contains RF shielding. All of these features provide robust signals and reliable power transmission, even in hostile environments.

Conclusion

The D110280 is a versatile connector that can be used for many applications including machine control, audio, and video. It offers superior signal transmission and dynamic range due to its multi-contact design, polarizing key and groove, and RF shielding. By understanding the application fields and working principle of the D110280, designers can better determine if it’s the optimal solution for their project.
