Description
BNC Jack (Female) to BNC Jack (Female) 4 Hole Flange Mount Adapter | Bayonet-lock | Brass Body
The ROSNOL AD-B2B27A-PF/94-94 is a precision flange mount adapter that supports 75 Ω impedance for RF signal continuity from DC to 1 GHz. It offers VSWR ≤ 1.35 (≥16.54 dB return loss), insertion loss ≤0.115√f GHz dB, and insulation resistance ≥5 GΩ. Test voltage reaches 1500 V RMS, with working voltage up to 400 V RMS. Power handling reaches 80 W at 2 GHz. The bayonet-lock coupling mechanism ensures robust connections and supports ≥500 mating cycles for dependable performance.
Centre contacts are beryllium copper with gold plating over a nickel-phosphorus underlayer, while bodies are brass with copper-tin-zinc alloy finish. PTFE insulators guarantee dielectric stability, and silicone rubber gaskets provide environmental protection.
What makes ROSNOL RF components different?
ROSNOL specializes in precision‑engineered RF connectors, adapters, cable assemblies, and microwave components designed for stable high‑frequency performance. Each product is manufactured using high‑quality materials such as stainless steel, brass, beryllium copper, and PTFE dielectrics to ensure low loss, reliable impedance control, and long‑term durability. ROSNOL products are built under ISO 9001‑certified processes and comply fully with RoHS and REACH requirements, providing globally trusted quality across diverse RF and microwave applications.
Why should engineers and system integrators choose ROSNOL?
ROSNOL delivers performance comparable to leading European and American RF brands, but at a significantly more competitive price point. The brand emphasizes rigorous mechanical precision, stable electrical characteristics, and consistent quality across every production batch. ROSNOL provides extensive customization options—including materials, plating, geometry, and mechanical configuration—making it ideal for OEMs, system developers, and engineers seeking optimized RF interconnect solutions without the premium cost associated with international big‑name suppliers.
When are ROSNOL RF connectors and adapters the right choice?
ROSNOL products are the preferred choice when projects require dependable RF performance in environments ranging from laboratory testing to telecom infrastructure, aerospace assemblies, IoT devices, and high‑density system integration. They are especially suitable when engineers need stable performance up to millimeter‑wave frequencies, robust mechanical endurance, or reliable alternatives to higher‑priced Western brands. Whether for prototyping or mass‑production deployment, ROSNOL components provide consistent, cost‑effective performance exactly when long‑term reliability and value matter most
