D-sub connectors are widely used in the electronic industry in a variety of applications. The D-sub connector, also known as the DBMN17H2PNK127, is a popular version of this connector type. In this article, we will discuss the application field and working principle of the DBMN17H2PNK127 D-sub connector.The DBMN17H2PNK127 is a digital D-Sub connector, which is usually used to connect digital/analog composite video signals in broadcast-level equipment. It is equipped with specialized, machined, non-replaceable, gold-plated contacts that ensure the highest possible signal transmission quality, even over long distances. The DBMN17H2PNK127 is constructed from a combination of a high-quality molded plastic and zinc die-cast body. It is also equipped with a die-cast shell, which provides superior EM/RF shielding capabilities and can guarantee a reliable connection even in the presence of high levels of interference.The DBMN17H2PNK127 is designed to utilize both pins and sockets as the contact element of the connector. The pin contacts are comprised of a spring-loaded, precision-fitted ferrule, which is embedded into the die-cast body. These pins are then machined to precise tolerance levels and are plated with 20 micro-inches of gold. The socket contacts are comprised of a machined cup, which is fitted with a torsion spring. This spring allows for a quick and reliable connection, and also allows for a high level of vibration and shock resistance.In terms of the application field, the DBMN17H2PNK127 is most commonly used in the broadcast industry, as it has the capability of carrying signals over long distances with minimal signal degradation. In addition, the connector has been approved for use in military, security, aerospace and in-vehicle applications where high levels of interference are present. Furthermore, this connector type has the capability to perform in extreme temperature environments, making it a great choice for harsh condition applications.As for the working principle, the DBMN17H2PNK127 utilizes a straightforward contact system. Upon insertion, the pins make contact with the sockets, and an electrical connection is established. This connection is further stabilized by the retention system, which is built into the connector’s housing. This system utilizes a set of pins, which when locked in place, form a secure and reliable connection between the pins and the sockets.The retention system is further reinforced by the die-cast body, which also provides additional shielding against EMI/RFI noise.In conclusion, the DBMN17H2PNK127 is a reliable and versatile D-sub connector, which is ideal for a range of applications, including broadcast, military and in-vehicle applications. With its rigid construction and specialized contacts, it provides high-quality signal transmission with minimal signal degradation, even over long distances. Furthermore, its integrated shield provides excellent protection against interference, while its retention system ensures a secure and reliable connection.
