Working Principles

The 89891-445HLF connectors are designed specifically with low profile and reliable connection capabilities in mind. The low profile design reduces the risk of wire snags and tangles. The connection between the contacts is maintained by a floating post, which adjusts itself to different mating heights or applications.The contacts are self-aligning and provide secure contact alignment in the female socket. The contacts are also shrouded to provide an EMC (electromagnetic interference) shield for the installed application.The 89891-445HLF connectors also contain polarised components such as housings, pins, and posts. This ensures that the connector can be mated securely and without any misalignments. The connectors are also designed to be easily assembled and disassembled for installation in an application.

Conclusion

The 89891-445HLF is a rectangular connector - headers, receptacles, female socket. It is designed to provide reliable connections for numerous applications that require low profile and easy assembly. Its high speed and reliable connection capabilities make it an ideal choice for applications that require fast data transfer rates and reliable connections. With its self-aligning features, it is great for applications that require polarised components or EMC shielding.
