Backplane Connectors - Contacts represent the complex and often demanding interconnects for high-speed data communication between multiple system boards and motherboards. In particular, the 208271-3 contact is a reliable solution for high-frequency signal transfer. This robust contact is ideal for applications where signal insertion loss, crosstalk, and contact resistance are critical. This article provides an overview of the 208271-3 contact, its application field, and its working principle.

Application Field

The 208271-3 contact is a dependable solution for high-speed data transfer and has become a standard for backplane connectivity. It is suitable for use in high-density board-to-board interconnect applications. It is an ideal solution for high-frequency signal transmission and features good signal integrity performance.

The contact is suitable for use in a wide variety of applications, including telecommunications, datacom, industrial, automotive, aerospace, medical, and networking systems. It is particularly suited for applications such as Ethernet communications, power interconnects, and bus structures.

The 208271-3 contact is also used for PCI-Express Gen3/Gen4 applications. It is commonly used in the networking industry to ensure reliable signal transfer in high-end servers, storage, and switches.

Working Principle

The 208271-3 contact utilizes a combination of a gold-plated spring-loaded contactor and gold-plated board contacts for signal transfer. The contactor is housed in a precision-molded elastomer with a PBT (polybutylene terephthalate) contact tail. The contactor and board contacts are mated together to form the connection.

The contactor is able to self-adjust to the varying thicknesses of the board contacts, ensuring a consistent mating and reliable connection. This feature, combined with the contact’s hermetic sealing, ensures that the electrical performance of the contactor is maintained over numerous mating cycles.

The contactor is also designed with a solder cup at the leading edge of the interface, allowing for easy hand soldering of the contactor to the board contact. This ensures a secure connection between the contactor and the board contact, thereby eliminating any issues related to the contactor being pulled away from the board during the mating and unmating cycles.

Conclusion

The 208271-3 contact is a reliable and secure solution for high-speed data transfer in applications that require reliable signal transmission and excellent signal integrity performance. It is suitable for use in a wide range of applications, including telecommunications, datacom, industrial, automotive, aerospace, medical, and networking systems. The contact utilizes a combination of a gold-plated contactor and board contacts for signal transfer, and is designed with a solder cup at the leading edge for easy hand soldering. Its self-adjusting feature ensures a consistent mating and reliable connection, making it an ideal solution for high-speed data transmission.
