TNC Bulkhead Jack, 50 Ohm, 4 GHz — Panel-Mount RF Port
The TE Connectivity 5227820-1 is a TNC jack (female socket) for panel-mount RF interconnect.
4 GHz Ceiling vs the 22 GHz OSP Sibling
The 5227820-1 TNC jack tops out at 4 GHz, while the TE 1057230-1 OSP jack (snap-on fastening, gold body) is rated to 22 GHz. Both are 50 Ohm, single-port, panel-mount jacks with solder termination and gold centre contacts, but the TNC's threaded coupling trades bandwidth for ruggedised retention — the OSP's snap-on is quicker to mate but less secure under vibration. For sub-4 GHz applications (cellular, ISM, GPS) the TNC is the more mechanically robust choice; above 4 GHz the OSP sibling is the correct fit.
No gasket or O-ring is listed in the spec — if an environmental seal is required, a separate sealing washer should be specified at the panel interface.
