Description
N Plug (Male) to BNC Jack (Female) | Straight Adapter | Screw-Lock & Bayonet-Lock | Brass Body
The ROSNOL AD-N1B25A/944-94 is designed for secure RF connectivity between N male and BNC female interfaces. It operates from DC to 4 GHz with 50 Ω impedance, VSWR ≤1.20, insertion loss ≤0.05√F (GHz) dB, insulation resistance ≥5 GΩ, test voltage 1500 V rms, and working voltage 400 V rms. Power handling reaches 80 W at 2 GHz. Coupling mechanisms include screw-lock on the N side and bayonet-lock on the BNC side, ensuring reliable engagement with axial captivation ≥28 N and ≥500 mating cycles. Recommended torque for N side: 1.0 Nm.Contacts are beryllium copper with gold plating over nickel-phosphorus underplating; bodies brass with copper-tin-zinc alloy; insulators PTFE; gaskets silicone rubber; coupling nuts brass alloy. The adapter withstands −65°C to +165°C and complies with RoHS.
ROSNOL’s precision-engineered RF components offer high quality and consistent performance at competitive pricing, making them a strong alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001–certified facilities and are fully compliant with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
