Description
BNC Plug (Male) to N Jack (Female) Adapter | Straight Design | Bayonet-Lock & Screw-Lock | Brass Body
The ROSNOL AD-B1N25A/144-H4 is a precision 50 Ω RF adapter designed to connect BNC Plug (Male) and N Jack (Female) interfaces in applications operating from DC to 4 GHz. With VSWR ≤ 1.2, low insertion loss, and excellent impedance stability, this adapter helps preserve signal integrity across RF communication systems, test equipment, antenna installations, and laboratory measurement environments. The combination of BNC bayonet-lock and N screw-lock interfaces enables fast connection on one side and secure threaded retention on the other.
The N-side center contact is manufactured from gold-plated phosphor bronze, while the BNC-side center contact uses gold-plated brass. The brass body features a copper-tin-zinc alloy finish that provides enhanced corrosion resistance and long-term durability. Phosphor bronze offers excellent spring characteristics and contact reliability, while PTFE insulation ensures stable dielectric performance across the operating frequency range.
ROSNOL AD-B1N25A/144-H4 is manufactured in ISO 9001-certified facilities and complies with RoHS and REACH requirements. It is an ideal solution for adapting BNC and N connector systems while maintaining reliable RF performance and mechanical durability.
