50 Ohm BNC Jack for 4 GHz Signal Paths
The bayonet lock gives a quick quarter-turn mate that holds under light vibration — common on test equipment, instrumentation panels, and RF distribution boxes where you need to swap cables without tools. The 500 V rating and 500-cycle mating life suit it for repeated connect-disconnect duty in lab or field-service environments.
Construction and Termination
Through-hole mounting with solder termination on both the centre contact and the shield. The zinc body carries a nickel finish — corrosion-resistant for indoor rack or panel use. Centre contact is phosphor bronze with silver plating, which gives good conductivity and solderability. The dielectric is PBT/polyester, a common choice for BNC connectors at this frequency range.
Operating Range and Durability
The 500-cycle mating life is typical for a BNC — the bayonet mechanism wears gradually, but for periodic cable swaps it will outlast the equipment refresh cycle.
