Backplane Connectors - Specialized: 51939-135LF Application Field and Working Principle

The 51939-135LF is a specialized type of backplane connector designed to provide a high-performance, low-cost solution for a variety of applications. The 51939-135LF is a versatile connector designed to support a wide range of data rates and frequencies while meeting the challenging demands of backplane applications.The 51939-135LF features a unique design which combines the abilities of a traditional backplane connector and a high-frequency differential connector. This connector is capable of supporting the high-speed transmission of both serial and parallel data in applications involving high-frequency transmission over short distances. The additional benefits of this design are the low insertion and withdrawal force for easier operation as well as increased durability and lower cost of ownership.The 51939-135LF is a three-pole connector that allows data buses, including Ethernet, USB, Serial, and other high-speed buses, to be connected over a backplane. The connector supports both AC and DC signals up to 24dB of insertion loss and 1000 MHZ of bandwidth. Additionally, the 51939-135LF is designed to maintain a 50-Ohm differential impedance, allowing for better signal quality and enhanced signal integrity.The 51939-135LF can be used in a variety of applications, ranging from networking, communications, and storage systems to industrial, automotive, and consumer applications. The connector is designed to meet the various needs of these applications by supporting both low- and high-speed transmission, and providing high signal integrity. It is also designed to be compatible with a wide variety of backplane systems and to provide superior shielding and EMI performance. In addition, the robust design of the 51939-135LF ensures that it is capable of withstanding the harsh environments often encountered in these applications.The working principle of the 51939-135LF is relatively simple. The connector is designed so that the center conductor of the backplane is connected to the center conductor of the connector, while the signal and ground planes are connected to the corresponding connectors. The different pins are then connected to the front panel as needed for the specific application. When a signal is present, the current will flow from the center conductor through the connector and onto the corresponding pins to the front panel. The signal will then continue through the circuitry of the device and be passed on to the other end of the connection, allowing for communication between the two devices.In conclusion, the 51939-135LF is a specialized type of backplane connector designed to meet the needs of a variety of applications that require high-speed transmission over short distances. The unique design of the connector offers a reliable, low-cost solution for a wide range of applications, and the robust design ensures that it can withstand harsh environments. With the increased signal integrity and low-insertion and withdrawal forces, the 51939-135LF is an excellent choice for a variety of applications.
