It is a single-port, through-hole PCB-mount design with a bayonet lock for quick tool-less mating. This is the base-series member of the 5227699 family, specified for applications where the 500 V rating provides headroom above typical BNC signal levels.
RF Performance and Signal Path
The 500 V voltage rating is notably high for a BNC; it means the dielectric spacing and PBT/polyester insulator support RF power applications or instrumentation where transient voltages are a concern, not just low-level signal routing.
Mechanical and Environmental
Construction and Materials
The body is die-cast zinc with a nickel finish — standard for BNC connectors in indoor and protected outdoor use, offering good corrosion resistance. Tin is a cost-effective choice for moderate cycle counts; if your application demands higher mating cycle life or a more corrosion-resistant contact interface, a gold-plated BNC (like the 1057230-1) would be a different connector family to evaluate. The dielectric is PBT/polyester, a common RF-grade insulator that maintains stable impedance across the temperature range.
