Backplane Connectors - DIN 41612

The DIN 41612 connector is a type of board-to-board backplane connector that originated in Germany and is used for high-density applications. It is a variant of the D-Subminiature connector and is often called a Eurocard connector. These connectors are widely used in industrial, medical, telecom, and military applications.

The connector comes in two versions, a type A, which is designed for power and signal applications, and a type B, which is designed for signal applications only. Both versions feature a rectangular pin arrangement in two rows and are built with a dielectric plus a shield layer to provide excellent thermal, electrical, and mechanical performance. The two rows of contacts for the DIN 41612 connector are often set up in a 2x48, 3x32, 2x64, or 3x64 pin configuration, depending on the application.

Applications of DIN 41612 Connectors

The main application of the DIN 41612 connector is in backplanes, which are used to interconnect circuit boards within a system. This is because the connector supports high-density applications that require a large number of contact points. The backplane connectors are also used to interface with measurement equipment, data systems, chip processors, robotics, and instrumentation in industrial and telecom sectors.

Working Principle of DIN 41612 Connectors

The working principle of DIN 41612 connectors is relatively simple. The connectors consist of two rows with a set number of pins that are inserted into each board that needs to be connected. The pins are arranged in a rectangular pattern so that they fit into the corresponding parts of each board. The two boards are then plugged together, with a lever locking mechanism ensuring that the two boards are firmly connected to each other.

When the two boards are connected, electrical signals can be transmitted between them through the copper contacts of the connector. The connection is made by the contact spring and insulation layer on the connector, forming a secure electrical bond. The connector also ensures that the two boards are mechanically connected by holding them together.

Conclusion

The DIN 41612 connector is a versatile backplane connector that is commonly used to interconnect circuit boards in industrial and telecom applications. It also has the capability to support high-density applications, thanks to its rectangular pin arrangement in two rows. The connector works by having two rows of pins that fit into corresponding parts of each board, and then being firmly locked together with a lever mechanism. Through this connection, electrical signals can be transmitted between boards.
