The TE Connectivity 5414168-3 is a TNC jack, female socket, built for 50 Ohm systems and rated to 11 GHz. It comes as a bulkhead-mount kit — panel-mount with a front-side nut — and includes all six pieces needed for one install: the connector body, a crimp contact, a ferrule, a gasket, a lockwasher, and a nut. The zinc body gets a nickel finish, the beryllium copper centre contact is gold-plated, and the dielectric is polymethylpentene (PMP). This is the kind of RF interconnect you spec for a fixed station antenna feed or a test point where you want threaded reliability and a clean 50 Ohm match through 11 GHz.
This jack accepts RG-174, RG-188, and RG-316 coax — three common small-diameter cables for RF up through low microwave bands. The kit format means you do not have to hunt down the right ferrule or gasket separately; the bag has one of each per connector. If you are building a harness for RG-316, this is a straight match — no adapter ring or alternative ferrule needed.
The 11 GHz ceiling is the practical limit; above that, the TNC interface geometry starts to degrade the return loss. For a 2.4 GHz or 5.8 GHz Wi-Fi backhaul, or a GPS antenna feed at 1.5 GHz, this connector has headroom to spare. The 500-cycle mating life is solid for a threaded RF connector — the gold-on-beryllium-copper centre contact handles the wear, and the nickel body finish resists corrosion in outdoor or industrial cabinets.
