DIN 41612 Backplane Connectors - 650911-5 Application Field and Working PrincipleDIN 41612 backplane connectors are primarily used in high-density computer and network equipment applications, as a means of connecting printed circuit board (PCB) components inside the main circuit board. In terms of size, these devices are relatively small; however, their primary function is to support the interconnection of multiple boards.The 650911-5 is a two-piece device composed of a two-row, 18-pin male connector and a two-row, 18-pin female connector. This slide-in mount variant of the 650911-5 backplane connector meets the requirements of the DIN 41612 standard and features an insulated temperature range of -40°C to +105°C. The most common applications for this backplane connector include mainframes, Telecoms equipment, process control systems, power supplies, and data processing.The 650911-5 backplane connectors’ working principle is based on the notion of transferring and relaying information over the same surface. The male connector utilizes 18 gold-plated copper contacts, delivering electrical signals between two mating components. Its female counterpart ensures a secure and reliable connection with two additional metal retention clips that secure the connector contacts into the female device. Furthermore, the 650911-5 connector features a durable plastic casing, which provides a superior insulation barrier and ensures a safe operation.This DIN 41612 backplane connector offers various advantages. First and foremost, its low profile design guarantees a minimal obstruction when installed in tight spaces. Additionally, it is produced with a keying feature, which ensures the correct mating of connectors and prevents mating between different pins. Additionally, due to its gold-plated contacts, the connector guarantees a high-performance contact resistance and ensures a safe and secure connection with no risk of short-circuiting.In terms of installation, the 650911-5 connector is reeled automatically onto PCBs, eliminating manual soldering, and can be mounted onto the board using either a reflow process or a soldering iron. The contacts can be distributed either horizontally or vertically, optimizing its electrical performance capabilities.In conclusion, the 650911-5 backplane connector is a reliable and cost-effective device for linking connectors on the backplane of several types of equipment. Despite its small size, this connector is capable of transferring electrical signals reliably and efficiently, due to its high-quality insulated casing, 18 gold-plated contacts, two metal retention clips, and its low profile design. As a result, the 650911-5 backplane connector is ideal for applications such as mainframes, Telecoms equipment, process control systems, power supplies, and data processing.
