D-Sub, D-Shaped Connectors are components that are used to safely join two circuits together. They consist of multiple pins that mate together when two components are joined. The most common form of D-Shaped Connectors is called a D-sub connector, which comes in a variety of shapes and sizes. The D20419-220 is a 9-Pin D-Sub male connector designed for professional audio, video and coaxial. This article discusses the application field and working principle of the D20419-220.

Application Field of D20419-220

The D20419-220 is ideal for connection of professional audio, video and coaxial products. It is suitable for unbalanced signal lines, such as earphone port and microphone lines, as well as balanced signal lines, such as XLR mic lines. Its rated current is 1A and the voltage rating is 30V AC/DC. It supports a maximum cable size of 7.5 mm.

Working Principle of D20419-220

The D20419-220 is a 9-pin connector with male terminals that mate to a female mating connector. It consists of a plug with 9 pins that correspond to the 9 holes of the female connector. It is designed for secure and reliable connections, as the pins of the male connector inserts into the female connector and secure it by using soldered joints. The connector has gold-plated contacts, so it has low contact resistance and good signal transmission.

The working process of the D20419-220 is quite straightforward. The male connector is first inserted into the female connector. Once it is firmly nested, the pins of the male connector press against the contacts inside the female connector, forming an electrical connection. Upon insertion, the connector should be visually inspected to make sure that there is a secure connection and that the contacts are properly aligned and firmly seated. Soldering the pins of the male connector provides a more reliable connection if needed.

The D20419-220 is part of the D-Sub line of connectors from Tyco Electronics. It is a reliable and easy-to-use connector solution for professional audio, video and coaxial applications. Its gold-plated contacts ensure a low contact resistance and good signal transmission, making it an ideal solution for connecting audio, video and coaxial devices.
