Coaxial Connectors (RF) have become increasingly popular as a means of providing a reliable connection between two pieces of electronic equipment. A particular type of coaxial connector, the 227661-1, is well-known as a reliable component for use in telecommunications, navigation, and some industrial applications. This article examines the application field and working principle of the 227661-1.

Application Field

The 227661-1 is designed for use with coaxial cables and is common in radio-frequency applications. It connects either an 8505-style coaxial cable assembly for up to 6.5GHz bandwidth or a 26500-style cable assembly for up to 7GHz bandwidth. It is suitable for outdoor applications, but may be used for indoor applications as well. Furthermore, due to its reliable, shielded connection, it can also be used for high-speed or high-power applications. Common usage scenarios include connection between antennas and radio-frequency equipment, such as switches or routers. It can also be used to connect communications modems or other pieces of telecommunications equipment.

Working Principle

The 227661-1 connector is a three-piece assembly. It comprises a center contact and two sunk shells. The center contact is designed for low-resistance contact between connectors and is made from gold-plated brass. This contact is held with a Teflon® insulator in the center of each shell and provides stability to the connection while maintaining a low signal loss. The shells contain an elastomeric rubber seal which inhibits passage of moisture and provides a reliable environmental barrier. The sunk shells and captive nuts on the connectors provide shielding against electromagnetic interference (EMI) and radio-frequency interference (RFI).

When correctly mated, the 227661-1 connector provides a reliable, robust connection between two pieces of equipment. The female portion of the connector houses the center contact and is designed to mate with the male portion of the connector. The center contact is held in place by a threaded nut which is tightened during the mating process. These components ensure a tight, secure connection which minimizes RF leakage and allows for a reliable, efficient transfer of power and data.

Conclusion

The 227661-1 connector is a highly dependable part of coaxial cable assemblies. Its application field is broad and includes outdoor and indoor applications, high power and/or high-speed scenarios, as well as radio-frequency applications. Its three-piece assembly requires a male and female connector as well as a center contact to provide a reliable, shielded connection. Its ability to provide a reliable connection and protect against EMI and RFI make it the perfect choice for your coaxial cable requirements.
