Backplane Connectors - Housings, commonly known as QR/P-8S-C(51), are widely used in a range of electrical and electronic applications. They are versatile, high performance connectors designed for reliable, demanding interconnecting environments. These connectors are specific to industrial applications, typically featuring a double-orientation design, which enables them to connect two different devices in the same plane. This article will explore the application field and working principle of QR/P-8S-C(51) connectors.The QR/P-8S-C(51) is often specified in the design of rugged communications backplanes for industrial applications. It has a 4 row-column two-level structure, allowing a maximum of 128 contacts per connector. Its small size and low profile design allow for flexible use in tight spaces. In addition to its modularity and adjustable height, it is also extremely resistant to shock and vibration.These connectors are widely used in the aerospace,automotive, telecommunication, industrial and medical industries, as well as in harsh environment applications. It is often used in segment assemblies for Ethernet and industrial components, as well as in aircraft backplanes for data, power and controlling applications.The working principle of QR/P-8S-C(51) connectors relies on its two level structure, which allows for a high degree of versatility. The upper level of the connector contains the electrical contacts, while the bottom level serves to mechanically join it to another connector. The pins are inserted into plated through-hole contacts, which provide a secure connection and significantly reduce cross-talk. The lower level of the connector has several mounting points, allowing it to be easily mounted to the printed circuit board. These points ensure a good electrical connection between the connector and the PC board.The QR/P-8S-C(51) connector also has four grounding points to ensure a secure electrical connection. The ground points are located around the perimeter of the connector and are designed to reduce ground loop and common mode noise. In addition, the connector also features a main board PCB stiffener, which reduces the amount of stress on the connector caused by contact mating and unmating.In conclusion, the QR/P-8S-C(51) connector is an excellent choice for demanding interconnecting environments. Its small size, low profile design, modularity and adjustable height make it ideal for the tight spaces that are commonly found in industrial applications.Finally, its four grounding points and main board stiffener make it highly resistant to shock and vibration, making it a reliable choice for rugged communications backplanes.
