Introduction:

D-sub connectors are one of the most commonly used types of interconnection products that are widely used in many different industrial and commercial applications. D-sub connectors are typically characterized by their rectangular shape, with two opposing sides connected to two different components. The D-Sub Connector is a universal connector that is used for a variety of applications. They are commonly found in audio and video equipment, computer and telecommunications equipment, medical and instrumentation equipment, and most other electrical systems.

DBMY21W1SA191 - Application Field and Working Principle

DBMY21W1SA191 is a D-Subminiature Connector that is designed to interconnect computers and other devices. This connector joins two printed or machined circuit boards, providing reliable, high-quality connections. It is specifically manufactured for high-voltage and power applications, and is UL-approved for 600V maximum current. This connector is a 21-pin, single-ended type with a 1mm pitch. It features solder cup pins, a slim body design, and is suitable for wire-to-board and board-to-board applications.Regarding its working principle, the DBMY21W1SA191 connector consists of a male and a female part, with a number of pins or sockets that make contact. The female part is referred to as a receptor, and the male part is referred to as a dipole. They are interconnected by inserting the dipole into the receptor. The tips of the pins make contact with the inside of the receptor, creating an electrical connection. To prevent interference, the DBMY21W1SA191 features built-in polarization to make sure that the connector is installed correctly.In terms of its application field, the DBMY21W1SA191 connector is primarily used in medical equipment, computers, instrumentation equipment, testing systems and other electrical and network applications which require a reliable and high quality connection. It is designed to be used in electrical systems that require a low profile and high power connector. It has been tested to withstand up to 600V, and is UL approved.

Conclusion

To conclude, the DBMY21W1SA191 D-Sub Connector is a high-quality, high-voltage connector suitable for a variety of applications in the field of computers, medical equipment, instrumentation, and other electrical systems. The connector is designed with a low profile and provides reliable connections between two printed or machined circuit boards. It features solder cup pins, a slim body design, and polarization, making it a viable option for many types of applications.
