Description
BNC Plug (Male) to BNC Jack (Female) Adapter | Bayonet-lock | Stainless Steel Body
The ROSNOL ADL-B1B25A/9XX-9X is a precision-engineered BNC L-adapter featuring male-to-female connectors, optimized for RF systems operating up to 4 GHz. It offers 50 Ω impedance, VSWR ≤1.2 (≥20.8 dB), and insertion loss ≤0.05 × √F (GHz) dB. With insulation resistance ≥5 GΩ and RF leakage performance ≥100 dB up to 1 GHz, this adapter ensures stable signal transmission. Mechanical specifications include bayonet-lock coupling, ≥500 mating cycles, axial captivation ≥15 N, and operating temperature range from −65°C to +165°C.Constructed with passivated stainless steel body and coupling nut, the adapter features beryllium copper center contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. PTFE insulators and silicone rubber gaskets provide excellent dielectric and sealing performance.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
