Coaxial Connectors (RF) - Adapters

Coaxial connectors are a type of cable connector specifically designed for radio frequency applications with a specified impedance of 50 or 75 ohms. Coaxial connectors are capable of providing highly reliable connections with low contact resistance and shielding from electrical interference and are therefore used extensively in digital and audio applications including antenna feeders, broadcast, telecommunications, CCTV and military applications.

242120 or ‘N’ Type adapters are a type of RF coaxial connector adapter with N type construction. They are widely used in applications such as cellular sites, broadcast television, microwave radio, RF test equipment, transportation and avionics. They also replace the less reliable twist-on connectors used in cellular sites, broadcast television, broadcast radio and the military.

The adapter uses a threaded coupling body that thread onto the N type connector, usually with a rubber gasket for sealing, providing the connections to the outer conductor that is necessary for electrical connection. The central contact pin is lowered onto the outer contact of the N type connector, providing the connection to the inner conductor.

The 242120 adapter is designed for use in applications where re-usability is a priority. The threaded joint and rubber gasket provide protection against corrosion or wear, allowing the adapter to be re-attached multiple times without affecting performance or compromising the connection. This is ideal for applications where disconnecting and reconnecting is necessary, such as in mobile data networks or telecommunications.

The 242120 adapter exhibits excellent electrical integrity when used with the appropriate connector, ensuring low-loss, reliable connections even in environments where interference and vibration are likely. The adapter offers excellent EMI/RFI shielding, helping to minimize interference and noise when transmitting or receiving data over cable.

The 242120 adapters are also designed to provide a quick and reliable connection or disconnection of RF coaxial cables. The connector housing is designed to grip the cable firmly, and the threaded joint allows for quick and easy mating or disassembly without the need for tools. This makes it ideal for use in applications where time is of the essence, such as in emergency response applications.

The 242120 adapter is available in both absolute and interlock configurations, and is easy to install and maintain. The reliability and low contact resistance of the adapter make it an ideal choices for a wide range of RF applications, including antenna systems, cellular networks, broadcast television, and microwave radio.
