Description
BNC Plug (Male) to BNC Jack (Female) to BNC Jack (Female) T-Adapter | Bayonet-Lock | Brass Body
The ROSNOL ADT-B2B1B25A/94-944-94 is a high‑reliability BNC plug to dual BNC jack T adapter designed for RF branching applications from DC to 4 GHz. Engineered with 50 Ω impedance, insulation resistance ≥ 5 GΩ, and excellent electrical stability, this adapter supports accurate signal splitting for test systems and instrumentation. The bayonet‑lock coupling mechanism ensures secure and rapid mating with consistent performance.The adapter features beryllium copper centre contacts with gold plating over a non‑magnetic nickel–phosphorus underlayer, providing low contact resistance and long‑term durability. The bodies and coupling nuts are constructed from brass with copper–tin–zinc alloy plating, and PTFE insulators maintain stable dielectric properties. Suitable for RF laboratories, telecommunications, monitoring equipment, and professional test racks requiring multi‑port BNC connectivity.
ROSNOL RF products comply fully with ISO 9001 manufacturing standards and meet RoHS and REACH environmental regulations. Offering high performance at competitive cost, they serve as a dependable alternative to leading European and American brands, with full customization services available.
