Description
BNC Plug (Male) to BNC Jack (Female) to BNC Jack (Female) T-Adapter | Bayonet-Lock | Brass Body
The ROSNOL ADT-B2B1B25A/H3-H33-H3 is a precision BNC plug to dual BNC jack T adapter designed for reliable signal distribution from DC to 4 GHz. This 1-plug, 2-jack configuration provides stable performance with 50 Ω impedance, insulation resistance ≥ 5 GΩ, and low contact resistance, ensuring dependable signal branching in RF test environments. With power handling up to 80 W at 2 GHz and bayonet-lock coupling, the adapter offers secure mating and long-term durability.The adapter is constructed using high-quality phosphor bronze centre contacts with gold plating over a non‑magnetic nickel–phosphorus underlayer. The brass bodies and coupling nuts feature nickel plating for corrosion resistance, while PTFE insulators deliver stable dielectric performance. This T adapter is suitable for laboratory test setups, RF instrumentation, telecommunications equipment, and signal monitoring applications requiring dependable multi‑port BNC connectivity.
ROSNOL RF components are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH requirements, offering high performance at competitive pricing as an excellent alternative to major European and American brands. Customized configurations, materials, and mechanical options are available to meet specialized project needs.
