Backplane Connectors - DIN 41612

DIN 41612 is a family of backplane connectors commonly used for linking printed circuit boards together. These connectors provide a high-density, cost-effective solution for linking boards within a box or enclosure. They are specifically designed for applications requiring multiple signals to be transferred in a short amount of time.

The DIN 41612 family of connectors is available in various sizes and pin configurations. These connectors typically feature anywhere from 12 to 80 contacts, allowing them to transfer multiple signals at once. Some of the features that help with these higher pin counts are the incorporation of cut-out "pockets" and alignment ribs, which provide a better fit and signal transfer performance.

The connectors also feature a wide variety of mating options, including solder contacts, quick-disconnects, or soldering tabs. These different mating options allow for flexible design, allowing users to choose the best mating type for their specific application. Additionally, they also offer a range of configurations to accommodate different PCB heights, such as the B1912 and B1918 series.

The DIN 41612 family of connectors also come in various contact sizes, including 1.78mm, 2mm, and 2.54mm, which allows for wider signal range. Additionally, their larger size contact-in-contact design provides additional shielding benefits. The contact plating is usually made from a tin-plated nickel material, making these connectors well-suited for harsh industrial environments.

Application Field and Working Principle

The DIN 41612 family of connectors is typically used in applications where several signals need to be transferred in a reliable and timely manner, such as industrial automation, or in telecom, medical, and broadcast equipment. The many different pin configurations and contact sizes make it easy to customize the connectors to any given application.

The working principle of the DIN 41612 connectors is based on a male and female contact system. The male contacts are housed in the backplane connector, with the female contacts being on the printed circuit board. During assembly, the female contacts are inserted into the socket of the backplane connector, and held in place by metal spring contacts. Both sets of contacts are then subjected to a wiping action, which causes the contacts to form an electrical connection. This wiping action ensures that the connection between the boards is secure and reliable.

The DIN 41612 family of connectors is an excellent choice for applications requiring a reliable and cost-effective connection solution. They offer a wide variety of features, including a range of pin configurations, contact sizes, and mating options, all of which help make them suitable for most applications.
