Rf Industries RFN-1021-2 N Female four 18 mm Hole Flange Post Terminal Ext Diele

The RF Industries RFN-1021-2 is a precision-built N-type female bulkhead connector designed for demanding panel-mount RF applications. Its four-hole flange configuration provides a secure, mechanically stable interface to enclosures and chassis, making it well suited for base station panels, test fixtures, laboratory equipment, and ruggedized field installations where connector integrity under vibration and repeated mating cycles is critical. The solder cup termination delivers a reliable, low-resistance connection to coaxial cable center conductors, while the nickel-plated brass body and gold-plated inner contact together ensure long-term corrosion resistance and consistent signal integrity up to 11 GHz across the full 50-ohm impedance standard.

Key features & benefits

• 11 GHz Maximum Frequency — Rated to 11 GHz, this connector supports a wide range of RF and microwave applications without introducing bandwidth limitations in the interconnect.
• Four-Hole Flange Mounting — The 4-hole flange with 1.00-inch bolt circle pattern distributes mechanical load evenly across the mounting panel, resisting torque and pull-out forces in high-vibration environments.
• Gold-Plated Inner Contact — Gold plating on the inner contact minimizes contact resistance, resists oxidation, and maintains stable electrical performance over thousands of mating cycles.
• Nickel-Plated Brass Body — The brass body with nickel outer plating provides a robust structural foundation combined with strong resistance to corrosion and tarnish in varied deployment environments.
• Solder Cup Termination — The solder cup termination style allows for clean, repeatable hand-soldering of the cable center conductor, supporting both prototype builds and production assembly workflows.
• 50-Ohm Impedance — Matched to the industry-standard 50-ohm impedance, the RFN-1021-2 integrates seamlessly into coaxial transmission lines without introducing impedance discontinuities.
