Description
BNC Jack (Female) to MCX Jack (Female) Adapter | Straight Design | Bayonet-Lock & Snap-Lock | Brass Body
The ROSNOL AD-B2M25A/93-91 adapter provides secure connectivity between BNC and MCX connectors for RF systems. Operating from DC to 4 GHz with 50 Ω impedance, it achieves VSWR ≤1.15 and insertion loss ≤0.05 × √F (GHz) dB. Electrical ratings include insulation resistance ≥5 GΩ, test voltage 1000 V RMS, and working voltage 400 V RMS. Designed for durability, it supports ≥500 mating cycles with bayonet-lock and snap-lock coupling mechanisms.The center contacts are beryllium copper with gold plating over nickel-phosphorus underplating for superior conductivity. Brass bodies feature nickel plating, complemented by PTFE insulators for excellent dielectric strength. The adapter withstands temperatures from -65°C to +125°C, ensuring dependable performance in demanding environments.
