Description
BNC Plug (Male) to SMB Plug (Male) Adapter | Straight Design | Bayonet-Lock & Snap-Lock | Brass Body
The ROSNOL AD-B1S15A/933-911 adapter ensures robust interconnection between BNC and SMB connectors for RF applications. With a frequency range from DC to 4 GHz and 50 Ω impedance, it maintains VSWR ≤1.35 and low insertion loss. Electrical specifications include insulation resistance ≥5 GΩ and reliable contact resistance. Mechanical integrity includes bayonet-lock and snap-lock coupling with ≥500 mating cycles.Constructed with beryllium copper center contacts and brass bodies, the adapter features gold plating over nickel-phosphorus underplating for optimal conductivity and corrosion resistance. PTFE insulators and silicone rubber gaskets ensure dielectric strength, while brass coupling nuts provide mechanical stability. The adapter withstands temperatures from -65°C to +165°C for dependable performance.
