DIN 41612 Backplane Connectors are widely used in audio/video, automotive, consumer, automotive, industrial, medical, computing, telecommunications, and military applications. Developed by the Deutscher NormenVerband (DNV) in the 1970s, these versatile, modular connectors are designed to ensure signal integrity and resist vibration in high-frequency boards. Their robust construction features a combination of varying numbers of pins, solder contacts, and beams that are designed for signal and power distribution on printed circuit boards.

Its application fields can be divided by signal types, such as digital, analog, power or special signals. Digital signals include RS-232,RS-422,USB, Ethernet, DVI-D, HDMI, etc. Analog signals often include audio, video, power, clock, and broadband. Special signals are IR signals, TV signals, WWAN signals, etc. In terms of application scenarios, such connectors can be applied to personal computers, telecommunication systems, industrial systems, data storage systems, automotive systems and consumer electronics.

The inner construction of DIN 41612 Backplane Connectors consists of two printed circuit boards (PCBs) placed side by side. The long side of the board contains the signal pins, and the short side contains the power pins. The signal pins are connected to each board with gold-plated compliant contacts. The power pins are also connected to the PCBs via compliant contacts but are soldered to the PCBs. A guide pin ensures a reliable connection between the two boards.

The working principle of the DIN 41612 Backplane Connectors is relatively simple. The two main components are the interconnects and the socket/pin connection. When the connectors are placed together, the pins/contacts fit into the sockets. This establishes an electrical connection between the two components. The socket/pin connection is made by either soldering the pins to the board or using compliant contacts. The interconnects can be used to secure the connectors together or to route signals around.

The compliant contacts used in DIN 41612 Backplane Connectors provide a secure connection between the two printed circuit boards. The contacts are designed to deform slightly during use, forming a secure connection without damaging the board. The compliant contacts also help to protect the delicate surface-mount technology components from damage during assembly and installation. The conformability of the contacts ensures a reliable signal path with minimal noise, making them ideal for high-speed applications.

To conclude, DIN 41612 Backplane Connectors are a versatile and reliable solution for connecting two PCBs. They feature robust construction and protective compliant contacts to ensure signal integrity and reduce interference. The connectors are suitable for a variety of applications such as digital, analog, power, and special signals. They are increasingly popular due to their ease of use and cost-effectiveness.
