Backplane Connectors - Specialized encompasses a wide variety of proprietary connectors, allowing designers to specify custom connections tailored for their applications. 85854-183LF, a low-profile, high-density, miniature interconnect system, is among the specialized connectors that can be used to great advantage.

Applications

The 85854-183LF is designed for reliable, high performance connections at data rates up to 25 Mbps in restricted spaces and any board-to-board stack within the range of 1 to 5 mm pitch. The versatile form factor also works well in applications such as cable connectors, allowing a wide range of configurations and functions in assembly.

The connectors are able to support multiple high-speed electrical contacts (>20 dB), making them an ideal choice for high-performance workstations, DSPs (digital signal processors), network routers, and communications systems. The higher density of the 85854-183LF allow enables designers to reduce overall connector size while maintaining signal integrity.

The system is also capable of transmitting signals nearly ‘twice as fast’ as previous generations of connectors, a great advantage in space-restricted areas. This performance should help designers achieve maximum design flexibility, reduce system size, and enhance overall product performance.

Specifications

The 85854-183LF has a modest operating range of 0°C to +60°C with multiple low-profile, miniature connectors featuring unique, 0.80 to 1.5mm (.031” to .059”) pitch profiles to accommodate up to 30 signal contacts. Its electrical contact resistance is highly respectable with values at or below 3 mΩ per pin while its durability at high speeds reaches over 1000 mating cycles.

This reliable, high-speed interconnect system also includes an embedded latching system, enabling secure, repeatable mating. The ultra-miniature form factor on 85854-183LF connectors provides a data transmission rate of up to 25 Mbits/s, allowing for greater transmission rates and throughput.

Working Principle

At the core of the 85854-183LF system are individual, miniature connector modules featuring internal connections between signal pin pairs. An integrated slide-locking mechanism ensures secure mating, helping to prevent accidental unplugging and misalignment of signal contacts.

The robust signal contacts are contained within the body of the connector, and are designed to maintain structural integrity even in the presence of stresses due to vibration, shock, or impact. This design also ensures that the contacts remain aligned and securely mounted, providing reliable signal transmission.

Additionally, the 85854-183LF connectors offer a significant reduction of the total transmission losses over other connector systems while maintaining excellent transmission accuracy in the presence of electromagnetic interference (EMI). This ensures low crosstalk and no signal degradation for much longer distances than other connectors.

Conclusion

For those looking for a reliable connection that can support high-speed protocol rich applications at higher transmission rates due to restricted space, 85854-183LF is an excellent choice. With its low-profile, high-density form factor and multiple signal cables up to 30 pins, this versatile interconnect system offers the necessary performance with a considerably reduced total cost.
