Backplane Connectors - DIN 41612

The DIN 41612 is a three-row backplane connector concept developed for numerous applications, such as computers, industrial and communications equipment. Backplane connectors from the DIN 41612 family are available in various pitches and are used mainly for connecting high-speed audio and video signals. In addition, the DIN 41612 has the ability to handle high currents, making them suitable for power supply connections.

Application Field

DIN 41612 backplane connectors are used in a wide variety of applications. They are found in the manufacture of computers, industrial and communications equipment, televisions, aircraft, consumer electronics, and other electronics devices. Widely used in high-speed applications, DIN connectors meet and exceed the requirements for signal and current integrity. The three-row connectors are also found on hard disks, motherboards, and system boards.

DIN 41612 connectors offer excellent stability and reliability, which is why they are widely used in mission-critical applications such as telecommunications, medical equipment, and aerospace systems. Furthermore, the easy-to-maintain modular design of the DIN 41612 backplane system enables multiple devices to be connected in various configurations.

Working Principle

The DIN 41612 is a three-row backplane connector system consisting of a signal and power strip sandwiched between two metallic shields or ground planes. The signal and power strips contain one or more rows of aligned and evenly spaced contact points, usually either male or female, depending on the type of application. The contact points are wired to the PCBs using soldering or push-on connectors.

The shields in the DIN 41612 are connected to the ground plane of the PCB to ensure proper shielding and signal integrity. This allows for shielding of the high-frequency signals and minimizes crosstalk between the signal and power strips, resulting in better performance. The shields also provide some mechanical stability to the connector assembly.

The DIN 41612 connectors are designed for high-speed applications and feature a rated contact current of 4A at a contact resistance of no more than 0.25 ohms per contact. The connectors can be used in unison with coaxial cables or other high-speed cables.

Conclusion

The DIN 41612 backplane connectors are widely used in a variety of applications, including computers, industrial and communications equipment, consumer electronics, hard disks, motherboards, and system boards. The three-row connector system offers excellent performance and stability and is suitable for use in mission-critical applications. The connectors feature a rated contact current of 4A and a contact resistance of 0.25 ohms or less.
