Backplane Connectors are critical components responsible for successful transmission of signals and power between backplane and daughter cards. The 51915-077LF is one such specialized backplane connector, capable of managing increases in both data and bandwidth requirements for today’s high-speed, high-density applications. This article will explore the application field and working principle of 51915-077LF.

The 51915-077LF is designed for use in a variety of industrial and telecom applications including switches, routers, and packet access equipment. It features power and ground contacts located on the front face, while signal and ground contacts are located at the rear. This arrangement is ideal for managing high-speed serial signaling and provides ninety degrees of contact in a minimal footprint. The use of Optical Fiber Links further enhances the transmission performance of the 51915-077LF by allowing users to take advantage of longer trace lengths and reduce overall resistance and noise in noisy environments.

When used in an application with very small height restrictions, the 51915-077LF provides an economical and compact solution. Its straight or slant directional locking system simplifies the installation process. Furthermore, its stainless steel contacts and cast body allows for vibration and shock resistance, thereby increasing the reliability of the system.

The working principle behind the 51915-077LF is based on a five-position backplane connector with special dual coaxial contacts. This provides two power sockets and three signal sockets; the rear socket consists of three contacts that can be paired in different configurations to two different ground planes. The five-position backplane connector also facilitates differential signal lines, reducing cross talk and signal losses.

In addition to its five-position backplane connector, the 51915-077LF has two additional contacts on its front surface. These two contacts provide a separate connection for fiber optics. This design enables the 51915-077LF to support transmission of data and power through two separate channels. The use of fiber optics ensures a low-resistance and error free signal, while providing higher speed data transmissions.

The 51915-077LF also features an improved EMI/RFI-shielding design. It consists of an inner body, which provides EMI/RFI shielding, and an outer layer of foil shielding. This design effectively reduces the radiated emissions, thus increasing the signal integrity of the system.

In conclusion, the 51915-077LF is an ideal backplane connector for high-speed, high-density applications. With its straight or slant directional locking system, fiber optics transmission, and EMI/RFI shielding, users can be assured of improved signal and power integrity, superior transmission performance, and an economical, compact solution.
