TNC Panel-Mount Jack for 50 Ohm RF Paths
The 031-6359: The threaded coupling and bulkhead rear-side nut mount make this a vibration-resistant panel-feed connector — the nut clamps to the panel while the lockwasher prevents loosening under thermal cycling or mechanical shock.
What the 2 GHz and 500-Cycle Ratings Mean for the Install
The 2 GHz max frequency is the usable bandwidth for this TNC interface — above that, the VSWR rises and the connector stops behaving as a controlled-impedance path. In practice, this covers most cellular, ISM-band, and GPS applications, but not higher-frequency microwave links. The 500 mating cycles are driven by the gold-over-nickel plating on the beryllium copper center contact; tin-plated RF connectors typically spec 100–200 cycles. If the connector is going into a one-time install (base station antenna feed), the cycle life is generous margin. For a test-jig panel where the connector is mated daily, 500 cycles gives roughly 2 years of daily use before the contact wear starts shifting insertion loss.
Kit Contents and Mounting Detail
The lockwasher goes between the panel and the nut to maintain preload under vibration.
