2-292189-3 Backplane Connectors - Specialized: Application Field and Working Principle

Whenused in high-speed backplanes, the 2-292189-3 backplane connectors are a veryspecialized type of connector that is designed to ensure reliable connectionsamong the different parts and layers of a printed circuit board. Theseconnectors are designed to provide the highest possible reliability andcapability for the fast connections within a system, and they can be found ina variety of electronic applications. This article will examine theapplication field for these connectors, as well as the working principleutilized.

Application Field

The2-292189-3 backplane connectors are specifically designed to meet the demandsof applications where very high speed data signal rates are required. Thismakes them quite suitable for applications such as high-speed digital bridges,backplane buses, Ethernet, SONET/SDH backplanes, and most other high-speedcommunicating systems. These connectors can also be used in power systemapplications, where they can provide high voltage and current contactingsolutions.

The2-292189-3 connectors are also quite suited for applications that require verylow reflections and very low-noise performance. This makes them ideal forapplications that require communication between two digital circuits, such ascommunication between FPGAs, ASICs, or processors. The relatively low profile ofthese connectors also makes them desirable in applications where board space isscarce.

Finally,these connectors have the ability to deliver accurate transmission lineimpedance characteristics. This is very important in applications where electricaland optical signals coexist. Since these connectors are also designed for use inhigh-speed applications, their self-grounding and internal noise eliminationfeatures can be very beneficial in such environments.

Working Principle

The2-292189-3 backplane connectors feature a contact design that is able to providebetter performance than most of the contact designs found in conventionalconnectors. This means that the contact area is optimized to provide betterelectrical and shielding performance, resulting in lower signal interference anddata transmission losses. The contact design also helps to ensure that a secureand reliable connection is maintained in high-speed applications.

Inaddition, the 2-292189-3 connectors feature an insulation displacement typecontacting system in which insulation is pushed between the two contact surfaces.This helps to reduce contact resistance and to ensure that the required electricaland optical characteristics are maintained. It also ensures that the contact areais kept clean, minimizing the chances of damage due to debris and oxidation.

The2-292189-3 connectors also feature a two-piece contact design, which helps toensure that the mating surface is fully maintained and that the contact pinsequally distribute their electrical force. This enables these connectors tomanage high-power and repeatable connections. The overall design of theconnectors is also made very robust, which helps to reduce the chances ofmechanical damage.

Finally,these connectors can also be used in combination with special insulation that canhelp to ensure that the signals remain stable and reliable. This insulating layercan reduce cross-talk and signal leakage, and it can help to ensure that theconnectors remain intact and operational in spite of high environmental factors.

Conclusion

Designedfor high-speed connections, the 2-292189-3 backplane connectors are agreat option for applications that require very high speed data signal rates.These connectors feature a highly optimized contact design, as well as theability to provide accurate transmission line impedances. They can also be usedin combination with special insulation if needed, and their two-piece contactdesign ensures that the required electrical force is evenly distributed. Withtheir wide range of capabilities, the 2-292189-3 backplane connectorsare definitely worth considering for any project that needs reliableconnections.
