Introduction to Coaxial Connectors (RF)

Coaxial Connectors (RF) are an electrical connection technology used for the transmission and reception of radio frequency (RF) signals. They are used in a wide variety of applications, including telecommunications, broadcasting, microwave communications, radar, satellite communication systems, and other areas. RF coaxial connectors typically consist of an outer shell or housing containing one or more components, such as pins, sockets, cable, or other materials that serve to secure the connection.

112961 Application Field and Working Principle

The 112961 is a miniature coaxial connector developed by Amphenol. It is specifically designed for applications in the broadcast, communications, avionics, industrial control and instrumentation fields. The connector has an extended mounting flange with four insulator posts and is compatible with panel thicknesses from 0.41mm (18 AWG) to 0.81mm (14 AWG). It is available in several sizes, including N, BNC, TNC and UHF types, and offers superior EMI and RFI protection.The polarizing key helps ensure proper mating of the connector, and the ground contact helps reduce signal interference. The inner contact is male, and the outer contact is female. The inner contact is supported by a gold or silver plated stainless steel pin, while the outer contact is supported by a gold or silver plated stainless steel ferrule. The contact spacing is optimized to ensure secure mating and enable proper and reliable connection. The contacts are available in both 50 ohm and 75 ohm variants.The connector features a unique design that combines shielding and grounding through a wide diameter shield, which improves the signal integrity of the system. The combination of solid build quality, superior contact design, and shielding performance makes the 112961 an ideal choice for use in demanding environments.Various commercial and, to a lesser extent, Government/Military specifications have been established for mating the 112961 coaxial connector. These include, but are not limited to, MIL-STD-22D, MIL-C-85781, IEC 601-3, and NEC 705 section 4-13. For a full list of applicable standards, as well as instructions for mating and mating accessories, please consult Amphenol’s 112961 datasheet.

Conclusion

The 112961 coaxial connector from Amphenol is a miniature, high-performance device that is ideal for use in applications such as broadcast, communications, avionics, industrial control, and instrumentation. It is designed to provide superior EMI/RFI protection, ensure secure mating, and provide excellent signal integrity and shielding performance. Additionally, the connector meets various commercial and Government/Military specifications, and is available in several sizes with both 50 ohm and 75 ohm variants.
