Backplane Connectors - Specialized: MMD21-0141DU Application Field and Working Principle

The MMD21-0141DU series backplane connectors are special hardware components that offer maximum performance in a range of industries and applications. They are used to connect multiple single or double-row Printed Circuit Board (PCB) backplanes, acting as a reliable mechanical and electrical connection for a wide variety of electronic applications. This article outlines the application field of MMD21-0141DU backplane connectors, as well as their working principle.

Application Field

The main application field of the MMD21-0141DU series backplane connectors is the interconnection of multiple single and double-row PCB backplanes. The connectors offer higher vibration and shock resistance compared to other types of backplane connectors, thanks to their robust construction and their ultra-low profile design. They are suitable for strict industrial and military requirements, and they are usually used in power supplies, telecommunications, medical and automotive solutions, as well as computers, servers and networking applications.MMD21-0141DU backplane connectors are available in a variety of pitch sizes, including .050, .100, .150, and .200. They are designed for high-bandwidth connections, with up to 12 rows and 30 columns of signals per board. The connectors can carry up to 40A per row, providing a higher power capacity compared to other backplane connectors. The mechanical retention features also provide a secure connection between the two cables, making the MMD21-0141DU connectors a reliable choice for applications that require secure connections.

Working Principle

The working principle of the MMD21-0141DU backplane connectors is fairly simple. The connectors are made up of two parts – the contact part and the crimp part. The contact part is usually made from gold-plated copper, while the crimp part is usually made from stainless steel. The two parts are pressed together and then soldered, creating an electrical connection.The contact part of the connector is designed to make contact with the traces on the PCB. The contact area of the connector is usually coated with a plating that improves the durability of the electrical connection, as well as the performance of the connector. The contact area is also designed to make contact with the traces on both the top and bottom of the board.The crimp part of the connector is highly resistant to vibration and shock, and is designed to make a secure connection between two cables. The crimp part is usually made from stainless steel, and is designed to be crimped onto the two cables to create a secure and durable connection.

Conclusion

The MMD21-0141DU series backplane connectors are a specialized hardware component used to connect multiple single and double-row PCB backplanes. They offer a higher vibration and shock resistance compared to other backplane connectors, and they are often used in power supplies, telecommunications, medical and automotive solutions, as well as computers, servers and networking applications. The working principle of the connectors is fairly simple, with the contact part making contact with the traces on the PCB, and the crimp part creating a secure connection between two cables. In conclusion, the reliability and durability of MMD21-0141DU backplane connectors make them an ideal choice for a wide range of applications.
