The bayonet lock provides quick, tool-less mating typical of BNC connectors used in test equipment, instrumentation, and RF signal routing. The through-hole mounting and solder termination suit it for PCB attachment where mechanical stability from the solder joints is needed.
The 50 Ohm impedance matches standard coaxial cable and RF system impedance. The 4 GHz upper frequency covers most common RF bands.
The body is zinc with a nickel finish — nickel provides decent corrosion resistance and a clean appearance for lab or indoor use. The center contact is phosphor bronze with silver plating; silver offers low contact resistance but tarnishes over time, so this connector is best suited for controlled indoor environments rather than outdoor or high-humidity installations. The dielectric is PBT/polyester, a common choice for BNC connectors rated to 4 GHz.
