Backplane Connectors - Specialized play an important role in many applications. 85838-120 is one of them. This connector is designed to connect high speed PC boards that require high signal integrity performance, such as embedded system, communications or networking backplane. 85838-120 is a high-performance backplane connector system with outstanding characteristics and features.

Application Field

85838-120 is especially suitable for applications in server, storage, embedded system, communications, networking, industrial, medical equipment and automotive. It can be used in applications which require high speed performance and high signal integrity, such as gigabit Ethernet backplane applications.

85838-120 has a small size and high density design which allows PCB designers to save more area and material of PCB boards in their systems. Its rugged construction makes it suitable for applications where board-to-board connection between multiple boards is needed. The high retention strength of the connectors prevents contact disengaging and ensures reliable electrical connection in field applications.

Working Principle

85838-120 backplane connectors abide by the IEEE 802.3 Gigabit Ethernet standard. It features a press-fit, resilient design with extended, staggered, locking post for secure mating and dual beam, slotted contacts for superior signal integrity. This connector provides higher performance than other standard products in the market with fewer pins per row and up to 17Gb/s line rate with lighted InfiniBand applications.

The backpanel mount receptacle extends the shielding wall from the top surface of the receptacle to the backing plane. This extension allows higher speed operations compared to traditional backplane systems. The extended wall prevents any crosstalk and improves its high-speed performance. The integrated pressure plate keeps the cable secured and protected in place.

The 85838-120 also features a high-density design that saves space and minimizes complexity and weight. This makes it suitable for applications that require a higher degree of power in limited enclosed space. It is also backwards compatible with legacy systems and paired with existing equipment, making it an excellent choice for designs that require a quick upgrade.

The 85838-120 connectors also provide high signal integrity at high frequencies because of their wide contact gap and multi-point contact. This improves the connector’s current handling capability and tolerance to EMI. Its plated, slotted contacts reduce contact force and improve longevity.

Conclusion

The 85838-120 backplane connector is a reliable and robust system designed for high speed and high performance applications. Its compatibility with existing systems and integrated features make it suitable for many applications, ranging from gigabit Ethernet backplanes to small embedded systems.
