It's a same-series conversion, meaning both ends are BNC female sockets, so you're not crossing to a different connector family. The 50 Ohm impedance tells you it's built for standard RF and video signal paths, not 75 Ohm broadcast video or audio runs. The straight body style and panel-mount bulkhead feature let you install it through a chassis cutout, secured by the included lockwasher and nut. The nickel body finish and gold-plated phosphor bronze centre contacts give it decent corrosion resistance and stable contact performance over repeated mating cycles in indoor or sheltered environments. The dielectric material is Polymethylpentene (PMP), a low-loss thermoplastic that holds the 50 Ohm impedance through the signal path. The isolated feature designation means the outer shell is not tied to the centre conductor — standard for a BNC barrel adapter.
Sourcing reality — obsolete part
TE Connectivity lists the 5414105-1 as Obsolete. If you need a consistent long-term supply, a 50 Ohm BNC bulkhead barrel adapter from another manufacturer may be the practical route, but no direct TE cross-reference exists in the evidence.
The bayonet lock on each end gives a quick quarter-turn mate that holds under light vibration — typical for test equipment, patch panels, and RF distribution. The panel mount bulkhead feature means you cut a hole in the chassis, pass the adapter through, and secure it with the included lockwasher and nut. The straight body keeps the cable axis aligned with the panel face.
