Backplane Connectors - Hard Metric, Standard

1645456-1 backplane connectors are hard metric and standard connectors that are specifically designed as faceplates or backplane connectors. They offer excellent digital signal integrity performance and competitive power and ground current capability. The connector range is suitable for high speed applications, up to three rows and 1.27mm centerline pitch. It is available in several versions, including a short key, long key, and double row version. Designed to meet the increasing demand for improved signal integrity, the connectors are designed to provide low EMI emissions, low crosstalk, improved high-speed transmission performance, and improved grounding.

Working Principle of 1645456-1

The 1645456-1 backplane connector has been specifically designed to provide improved digital signal integrity performance with minimal power loss and ground current capability. The working principle of the connector involves the use of two interlocking clip assembly pieces, comprising a female clip assembly and a male clip assembly. The female clip assembly is provided with a set of contacts, which are connected to the ground contact area of the card. The male clip assembly is provided with a set of corresponding contacts, which are connected to the signal contact area of the card. Each clip assembly contactset has two rows of interlocking pins that provide the signal and ground connections.

The two snap together clips contact with each other in such a way that their mating surfaces create a high-frequency shielded connection. This design eliminates noise pollution and effectively isolates the power and ground pins from each other. The contacts of the two clip assembly pieces mate in a latch-lock manner and hold securely without coming loose. This ensures reliable data transfer and prevents incorrect contact mating.

For even greater power and ground current capability, the 1645456-1 hard metric standard backplane connector is provided with an embedded grounding system. This system is designed to provide improved grounding capability when connection is made to the panel or card. The enhanced grounding capability helps to maintain a stable electrical environment by providing good signal integrity and improved power and ground current capabilities.

Applications of 1645456-1

The 1645456-1 hard metric standard backplane connectors meet the international EIA-215 standard for high-speed performance and provides easy segregation and high-fidelity signals for rack-mountable systems. The connector is thus suitable for a wide range of applications including telecommunications, medical equipment, signal interface, and data communications. It is also widely used in a number of industrial applications, including embedded controllers, power supplies, motor drives, programmable logic controllers, and real-time embedded applications.

The 1645456-1 backplane connector is robust and reliable, as the performance of the contact surfaces ensures that the connectors have very low contact resistance and good damping, providing long service life and excellent shielding performance. The robustness and high reliability of the connector make it ideal for mission critical applications or applications that must be able to stand up to hostile environmental conditions.

Flexible cost-effective solutions are also offered by the 1645456-1 backplane connector, due to its small size and high density design, which provide increased levels of cost savings and high performance. Combined with increased signal continuity, this makes the 1645456-1 a perfect choice for many applications.

Conclusion

Overall, the 1645456-1 hard metric standard backplane connector is a high-performance product that offers excellent signal integrity performance and competitive power and ground current capability. It is suitable for a wide range of applications including telecommunications, medical equipment, signal interface, and data communications. The connectors offer excellent heat dissipation in comparison to other similar products, ensuring their performance remains reliable even in extreme environmental conditions. Their robust design and ease of integration also make them an ideal choice for mission critical applications.
