51915-261LF

The 51915-261LF is a specialty backplane connector designed to meet the needs of demanding applications where high system speeds, low crosstalk, high density and power delivery are increasingly important design considerations. Essentially, this connector provides the capability of connecting multiple signals and power lines between several planes of a backplane board. Therefore, it is often deployed in high-performance systems in the industrial, medical, telecommunications and military markets.

In general, for a connector to be used as a backplane connector it should meet certain criteria. Generally, a backplane connector should be able to transmit high-speed data with minimal crosstalk and EMI emissions, be available in many different sizes and configurations, have the capability of accommodating increasing numbers of pins, and provide specialized features such as differential signaling and twisted pair wiring. The 51915-261LF is a unique offering featuring all of these essential characteristics and more.

At the heart of the 51915-261LF is a special two-piece receptacle and plug design featuring electrical contacts that are compliant to the latest high-speed I/O standards. These contacts are offered in a variety of pin counts, including 72, 84, 96 and 120 positions. The plug housing is made from durable plastic and is designed to make the user’s experience as ergonomic as possible during mating and unmating. The receptacle housing is a two-piece system that tightens securely over a printed circuit board (PCB).

To meet the requirements of high signal integrity and power delivery, the 51915-261LF utilizes two specialized design features. First, the terminals on the contacts are designed with a reverse profile to reduce signal reflections that could contribute to crosstalk and reduce the problems associated with return paths. Secondly, the housings are designed with a special power distribution grid that allows multiple power lines to run through the connector, providing up to 25 amps of current.

The 51915-261LF is a high-performance, cost-effective solution implementation for applications requiring high-speed signal transmission and power delivery. It is designed to minimize crosstalk and EMI emission, provide high signal integrity and power delivery, and is offered in many different sizes and configurations. With its ability to meet the needs of demanding applications, this specialized backplane connector is an ideal solution for a wide variety of industrial, medical, military or telecommunications systems.
