Backplane Connectors - DIN 41612

DIN 41612 connectors are a special type of backplane connectors used for board-to-board applications. They are high-density connectors used in many applications including printed circuit boards (PCBs), servers, telecoms, and industrial controls. DIN 41612 connectors are available in two pin lengths: longer pins for larger PCBs and shorter pins for smaller PCBs. They provide a reliable connection between the PCBs and their components.

ELF Connector

ELF connectors are one variant of the DIN 41612 connector family. ELF connectors feature a 2 row, 8-24 pin contact arrangement that is used to create stackthrough configurations. The connector provides high reliability, even under extreme environmental conditions. It is designed for ease of use and rapid board-to-board assembly and various ELF connectors are available for different applications.

Applications

The ELF connector is commonly used in telecoms and military applications. It is used for stackthrough connections between PCBs. It is designed for high repeatability, no wear-out, high reliability and long life. It has been used in aircraft systems, fuel pumps, data transmission devices, security systems, military and aerospace systems, and many other applications.

Working Principle

The ELF connector operates on the principle of “Quadrant” technology. The contact-force between two pins is provided by four geometrically arranged spring fingers, which generates equal centric radial forces for all contact geometries. A contact gap between the contact surfaces, virtually free from any foreign material, ensures no degradation in application until it is replaced with a new connector. This ensures high reliability and low insertion and extraction forces, facilitating a smooth connection of the PCBs.

Conclusion

The ELF connector, part of the DIN 41612 connector family, is an ideal solution for board-to-board applications that need a high-density connection. It provides reliable connections with no wear-out and long life, even in extreme environmental conditions. ELF connectors have been used in many applications including telecoms, military, aircraft systems, data transmission, security systems, and more.
