Description
BNC Plug (Male) to BNC Jack (Female) to BNC Jack (Female) T-Adapter | Bayonet-Lock | Brass Body
The ROSNOL ADT‑B2B1B25A/H3‑133‑H3 is a compact BNC Plug to dual BNC Jack T‑adapter designed for RF signal branching from DC to 4 GHz. With 50‑ohm impedance, high insulation resistance, and a 1500 V rms test voltage rating, it supports reliable low‑loss signal distribution in multi‑port RF paths. The bayonet‑lock interface ensures quick, secure coupling, and the adapter provides at least 500 mating cycles with 15 N contact captivation.The adapter features phosphor bronze or brass center contacts with gold plating over a non‑magnetic nickel‑phosphorus underplating for strong conductivity and corrosion resistance. Nickel‑plated brass bodies enhance structural durability, while PTFE insulators maintain stable dielectric performance. A silicone rubber gasket adds environmental sealing. These materials make the ADT‑B2B1B25A/H3‑133‑H3 suitable for RF test benches, signal monitoring setups, and applications requiring dependable BNC signal splitting.
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 are available to meet specialized RF and microwave application requirements.
