RFI and EMI - Contacts, Fingerstock and Gaskets

Introduction to 8863-0202-72

The 8863-0202-72 ("8863") is a standard contact, fingerstock, and gasket used in the field of radio frequency interference (RFI) and electromagnetic interference (EMI) shielding. These contacts are used in applications where strong signal or noise protection and prevention are necessary, like RF shielding for sensitive electronic devices. Specifically, 8863 contacts are used to shield circuit boards, create volume conductive gaskets, seal EMI covers, and form better contacts between metal frames/chassis.

Applications and Advantages of 8863

The 8863 contact has a variety of benefits and applications, both in terms of excellent RFI/EMI shielding and robust physical characteristics. 8863 contacts/fingerstock possess an exceptionally low contact resistance, less than 5 milliohms, which can reduce the number of I/O ports a shielding system needs. The low contact resistance of 8863 also allows it to be used with smaller current loops, which further reduces the amount of power it requires to operate. The 8863 is also able to produce a very reliable and consistent connection bond through its standard male/female crimps. In terms of RFI/EMI shielding, 8863 contacts provide exceptional attenuation and eliminate high-frequency interference.

Working Principle of 8863

8863 contacts are usually installed via an efficient crimping process. The 8863 is specifically designed to provide superior contact-to-crimp bonding and reduce contact loss over time. Essentially, a crimping tool shapes the male and female 8863 contact pieces together into a pair of joined metal tubes. The crimping process produces the most secure contact bond as the two pieces are affixed via mechanical interlocking. Furthermore, the process also increases contact and signal path-continuity, which improves RFI/EMI shielding performance.

Conclusion

The 8863-0202-72 is an invaluable contact, fingerstock, and gasket product that serves a variety of different functions in applications requiring RFI/EMI shielding. It is able to provide a reliable and consistent connection, as well as effective signal protection and optimized power usage. The 8863 is typically installed through a crimping process, which further enhances its contact-to-crimp bonding and produces secure physical interlocking. All in all, the 8863 is an ideal choice for creating a strong signal or noise protection shield in various electronic devices.
