131A12039X

D-Sub, D-Shaped Connectors - Contacts are typically applied in a variety of electronic applications where precise signal transferring electrical interconnections are essential. The 131A12039X product is one such offering and the purpose of this article is to explain the application field and working principle of this connector type.

Application Field

The 131A12039X model is a 19-pin D-Submale connector with crimp type contacts. It is widely used to connect micro-controllers, Ethernet ports and other digital electronic devices. It is also widely used in laptop computers, network switches, personal computers and many other applications that require high speed data transfer.

Working Principle

The 131A12039X is a low profile connector with a contact force of 0.5N (5 g). The contact force is low enough for high speed operations, making it ideal for higher bandwidth applications. The contacts are sized to match the mating component, providing a secure connection. The contact pins are made from brass and plated with a gold coating, providing a non-corrosive and low resistance electrical connection. The contacts have an excellent thermocouple effect which makes them suitable for high temperature environments up to 125°C.

The design of the 131A12039X connector allows for easy and repeatable installation using standard crimp tools. The terminals are soldered on the board and the connector is crimped tight to the terminals, forming a strong mechanical connection.

Conclusion

The 131A12039X is a 19 pin D-Submale connector with crimp type contacts. It is widely used to connect digital electronics equipment and is designed for high speed applications. The connector is designed with a contact force of 0.5N and is plated with a gold coating for low resistance and corrosion resistance. The terminals can be crimped for an easy and repeatable installation, making it an ideal choice for high-performance applications.
