BNC Plug (Male) to TNC Jack (Female) RF Adapter | Bayonet-Lock to Screw-Lock | Brass Body
The ROSNOL AD-B1T25A/133-H3 is a high-reliability BNC Plug (Male) to TNC Jack (Female) straight RF adapter designed for 50 Ω applications from DC to 4 GHz. It maintains a low VSWR of ≤ 1.20 and insertion loss ≤ 0.05 × √F (GHz), ensuring efficient signal transfer. The BNC connector features a bayonet-lock mechanism that enables quick connect and disconnect, making it suitable for rapid installation scenarios, while the TNC connector provides a threaded screw-lock interface for improved vibration resistance and stable electrical performance.
This adapter is constructed with a brass body and nickel plating, offering a balance of conductivity and durability. The center contacts are made of phosphor bronze and brass with gold plating to ensure consistent signal integrity. PTFE insulators provide stable dielectric performance. Brass construction delivers good electrical conductivity and cost efficiency, while nickel plating enhances corrosion resistance and wear durability.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
