Backplane Connectors - Accessories

Backplane connectors are an important component used to transfer power and control signals between the different parts of a system. The D250-50690 is a popular model of backplane connector that is designed to be used for a wide range of applications. This article will explore the application field and working principle of the D250-50690 backplane connector.The D250-50690 backplane connector is a modular, 3-slot, shielded connector, which provides a simple and cost-effective way to interconnect both mechanical and electrical components. It is designed to accommodate up to seventeen different signals, including differential signal pairs, power signals, and power return signals in the same connector. The connector features a keyed, blind-mate interface, which allows it to be conveniently mounted to a variety of PCBs.This connector is especially suited for applications such as time-critical communication networks, automation systems, and industrial systems. It is also commonly used in computer systems, high-speed data systems, and power distribution systems. The connectors are designed for installation in a variety of environments, from high-temperature and high-vibration industrial settings to medical and aerospace applications.As far as the connector\'s technical specifications are concerned, the D250-50690 is available in two versions—one with rocker-button modules, and another with screw-type modules. The connectors have a nominal operating voltage of 30 VDC and a maximum operating voltage of 42 VDC. The connectors also feature a maximum operating current of 5.5A, a maximum contact resistance of 2 mΩ, and a dielectric strength of 1.5 kV for 1 minute. Furthermore, the connectors feature a Life-Cycle Endurance (LCE) rating of 10000 cycles, an IP67 protection rating, and a robust, 100% EMI and RFI shielding. The mated pairs are held together securely by two latch levers on the side of each module.In terms of its working principle, the D250-50690 backplane connector features a standard distribution bus configuration. This means that the individual connections are routed through a central bus that is fed to each of the individual backplane pins. On the rocker-button version of the connector, the power and control signals are routed through separate conductors within the connector\'s housing, while the screw-type version has each of the individual pins connected to two separate connections via the screw terminals.Once the connectors are mated, the power and control signals flow through the central bus, and the pins on the mated sides of the connectors receive their respective signals. This process is referred to as “distributed architecture”, and it ensures that the signals are accurately routed to their respective pins.The D250-50690 backplane connector is a versatile and cost-effective solution for a wide range of applications. Its modular design, robust shielding, and reliable connection technology make it ideal for both high-performance and low-voltage applications. Additionally, its innovative distributed architecture and high Life-Cycle Endurance rating make it an efficient and reliable choice for use in a variety of systems.
