Backplane connectors are a type of interconnection device, used primarily in modern electronic systems. The 516-230-438 backplane connector is a robust, reliable, high-density, low-profile connector specifically designed for applications requiring advanced mechanical and electrical characteristics. As an accessory, it can be used to modify existing backplane architectures, making them more suitable for specific applications.

Main Characteristics

The 516-230-438 backplane connector offers both high-density and high-strength. With its optimum mix of rigidity, strength and flexibility, it has been manufactured to provide exceptional levels of performance in both militarized and commercial applications. Its low profile design and wide range of options allow for optimized usage for either ruggedized harnesses or backplanes with limited mounting depth.

Material & Construction

The outer shell of the 516-230-438 backplane connector is manufactured from a single piece of high-strength glass-filled thermoplastic (Monsanto 8500 LVM). The interface pins and surface mount pads are constructed from copper-based alloys that provide excellent electrical performance. The interface pins and surface mount pads are plated with tin-lead for additional strength. Finally, the finishes are then custom formulated for improved corrosion resistance and optimum contact performance.

Environmental Considerations

The 516-230-438 backplane connector is designed to operate in a wide range of environmental conditions, such as extreme temperatures, high humidity, shock, vibration, and exposure to liquids and corrosives. In addition, the connectors have been tested to stringent requirements to ensure reliable performance in both civilian and militarized applications. It is UL recognized, and meets the following standards: UL 94 V-0 Flame Class Rating, UL 1977, VDE 0888, MIL-STD-202F, and CSA 22.2 No. 203-93.

Working Principle

The 516-230-438 backplane connector operates using an electrical principle called "series-mode impedance matching". This principle works by connecting the multiple electrical contact points within the connector in series, reserving the same nominal impedance for each contact. As a result, uniform signal transmission is maintained over the entire interface. The connector also utilizes a cross-member contact clip technology, which significantly reduces system insertion force, as well as the chance of unintentional detachment.

Conclusion

The 516-230-438 backplane connector is the perfect choice for applications requiring robust and reliable performance. Its combination of advanced design and material construction provide excellent performance in a wide range of environmental conditions. With its high density, low profile, and strong mechanical and electrical characteristics, this backplane connector has become the leading choice for an increasing number of modern electronic systems.
