Coaxial connectors, also known as RF connectors, are used for carrying signals and data in a variety of applications. CNF3 (Coaxial N-type Female connector), is a popular type of these connectors and is commonly used in various applications. This article looks at the application fields and working principles of CNF3.

Applications

CNF3 is a popular types of coaxial connectors as it is considered to be reliable as well as cost-effective. It is ideal for use in applications that require low power and low frequency signals, such as short-distance data transmission, in-house or local network cabling, telecommunication applications, LTE / WiMax / HSPA data links, etc. It is also used in satellite and terrestrial TV signal transmission, radio broadcasting, HF/VHF applications, computer networks, medical equipment, and test and measurement. It is also used in industrial, military, aerospace, and automotive applications.

Construction

The CNF3 connector is constructed of an inner connector and an outer casing. The inner connector is made of brass and has a threads on the shaft and a quick-release bayonet coupling system. The inner connector is typically fitted with a plastic insulator. The outer casing is made of die-cast aluminum and provides protection from EMI (electromagnetic interference). The outer casing also prevents moisture, dust and dirt from getting to the inner connector.

Working Principle

The working principle of CNF3 is based on a two-piece design. The first part is the inner connector which carries the signal. The second part is the outer casing which provides EMI and environmental shielding. The two parts are connected via a coupling mechanism such as quick-release bayonet or threaded coupling. The inner part ensures good electrical contact with the conductor of the cable and the outer part provides environmental and EMI protection to the inner part. The coupling mechanism ensures a secure connection between the parts.

Conclusion

CNF3 connectors are popular in a variety of applications due to their reliable construction and cost-effectiveness. With its two part design, the CNF3 is able to provide a secure connection without sacrificing on EMI and environmental protection. This makes it a popular option for in-house or short-distance data transmission, LTE / WiMax / HSPA data links, radio broadcasting, HF/VHF applications, and many other applications.
