311P405-10S-B-12 Application Field and Working Principle

D-subminiature (D-sub) or D-shaped connectors are commonly used for many applications because of their versatility and availability in different configurations. They are characterized by the ‘D’ shape of their housings and the number of pins they have. 311P405-10S-B-12 is one type of D-sub connector that is typically used in applications where smaller footprint and/or reliability is needed.

Types

311P405-10S-B-12 is a sub-miniature version of a standard D-sub connector with a number of different configurations such as: 10 pins in an 8-pin configuration, 7 pins in a 5-pin configuration, and 4 pins arranged in a 2-pin configuration. The connector also features a unique plastic support block to ensure secure and stable PCB connections, as well as a special assembly that prevents pins from coming loose.

Advantages

The use of the 311P405-10S-B-12 connectors provides several advantages over other types of D-sub connectors. It offers superior electrical performance, reliable connections, and a small footprint, making it suitable for use in confined spaces. Its plastic support blocks also provide extra protection to the contacts and prevent them from coming loose during operations.

Applications

Due to its size and features, the 311P405-10S-B-12 D-sub connectors are mainly used in applications where space is a critical factor. This includes computers, laptops, cameras, medical equipment, industrial control equipment, and other electronic applications. It is also a reliable connector for spaces where vibration and shock are present.

Working Principle

The 311P405-10S-B-12 D-sub connector has a standard symmetrical ‘D’ shape enclosure with electrical contacts on both outer halves. The contacts on each side are generally female and male, respectively. It is also designed with plastic support blocks on the back of the housing that ensure secure and stable PCB connections. The contacts are usually press-fit into the various slots of the plastic support blocks. Electrical signal is transferred through the mating between the male and female contacts. While assembled, a metal shell encloses the connector and prevents the contacts from being touched.

Conclusion

The 311P405-10S-B-12 D-sub connector is a reliable and robust electrical connector used for many electronic and industrial applications. It is mainly used in places, where smaller footprint and/or reliability is needed. It also offers superior electrical performance and reliable connections. The metal shell of the connector prevents any electrical contact and ensures safe operations and connections. Finally, the special plastic support blocks ensure secure and stable PCB connections.
