Backplane Connectors - DIN 41612

The DIN 41612 connectors, referred as the 122A13179X, are a family of electrical connectors commonly used to connect individual printed circuit boards (PCBs) to the "backplane" (a broader PCB acting as central wiring hub). This type of connectors is mainly used in industrial automation equipment, such as robots, process control systems, and automotive electronics.

Application

DIN 41612 connectors are especially suitable applications that require high-speed data transfer rates. The dimensional and mechanical arrangements of the components allow big space savings on the backplane. Each place on the backplane can contain both male and female reverse-end version of this connector. This feature allows multiple connections between several PCBs that are placed on the backplane.

Moreover, the speed of the connections has also been improved since DIN 41612 connectors have high operating frequencies.The contact connectors provide reliable connections with low electrical contact resistance, which supports high power transmission between two printed circuit boards.

Also, one of the major advantages of DIN 41612 is that the male part can be used to stabilize and secure the PCB on the backplane, if long board carriers are used. This helps to eliminate vibrational problems and improves the reworkability of the backplane because the PCB can be easily removed from the backplane.

Working principle

The122A13179X is a double-deck backplane connector with corrosion-resistant-copper contacts, 31 contacts per column, and 4 columns. The signal contacts are staggered from the adjacent parallel connector strip. The connections are made from standard thickness boards.

The DIN 41612 connectors are designed in a simple parallel modules, where every male pin has a corresponding female socket, ensuring for reliable connections. It also includes a dielectric insulation for contact connections which will prevent any short-circuits. The connectors also use a robust and reliable locking mechanism with a module locking system.

To ensure stability and reliable signal transmission, the ground terminal on the DIN 41612 is divided in three sections; ground on the top edge, ground on the bottom edge, and ground space on the middle. This offers maximum stability and better signal transmission throughout complex backplane systems. Additionally, the connectors are able to support current ratings from 1A to 12A dc.

Conclusion

It is clear that DIN 41612 connectors are a perfect choice when it comes to large and complex systems requiring closely spaced connections. The connector is compact, and it offers robustness and reliable signal transmission without sacrificing the space efficiency. Furthermore, it is relatively inexpensive and easily installed.
