Backplane Connectors - Specialized

The 51940-282LF is a specialized backplane connector used in applications where power, signals, and data must be routed through a single connection point with extreme reliability. This type of connector is designed to ensure secure connections between a main controller board or a backplane and a variety of peripheral or remote boards in embedded systems. Its characteristics include a high-density pin header and receptacle, a cross device connection system, high frequency data transmission capabilities, power dissipation capability, and rapid and reliable mating. It is perfect for use in a variety of applications where high reliability is mandated.

The 51940-282LF is a connector used extensively in backplane architecture, which acts as the primary electrical and mechanical interconnect between various units/modules of systems. Backplane connectors are a must for interconnecting several data and power carrying slots in ambient and high vibration conditions, as well as making them more reliable and suitable for mass production. The connectors are used in applications such as Ethernet networks, industrial automation, medical equipment and consumer electronics, and others.

Applications

The 51940-282LF is commonly used in applications where its high power dissipation capability and reliability are essential. This particular connector is typically used in a variety of medical, military, telecommunication, industrial control, avionics, and commercial applications, including routers, switches, blade servers, data storage, and portable computers. It is the preferred choice in applications requiring reliable interconnection between a base board and multiple daughterboards. It simplifies the installation of daughterboards in a mother board or backplane through its single connection point.

Working Principle

The 51940-282LF utilizes a socket and a field contact as its main interconnecting components. The wire socket is mechanically mated and splayed with the corresponding field contact ensuring a secure connection. The vertically arranged pins pass through the mating female connector to create a reliable and secure single connection point. This connector provides a visible action when mating, releasing the field contacts with a click to communicate successful connection. Female connector pins can also be provided with extra protection from over insertion.

The five pins of the 51940-282LF extra wide field header form a symmetrical line of evenly spaced contacts providing maximum flexibility for the design. This type of connector also features a power dissipation capability that enables higher current levels than typically found in a similar assembly, allowing peace of mind when designing innovative high power applications.

The 51940-282LF is based on a dielectric strength of 25V, insulation resistance of 100MΩ, and contact resistance of 30MΩ. Its special feature is its mechanical design: a long narrow field contact sleeve connected to a yoke eventually affixed to a backplate. This design ensures reliability in both high vibration and atmospheric pressure conditions.

Conclusion

The 51940-282LF is a specialized backplane connector that offers an ideal solution for applications where power, signals, and data must be routed through a single connection point with extreme reliability. It has many advantages, such as rapid and reliable mating, high frequency data transmission, and power dissipation capability. It is the preferred choice in applications that require secure connections between a main controller board and its peripheral or remote boards, and is used in a variety of application areas.
