Description
FME Plug (Male) to BNC Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-E1B25A/14-94 is a precision RF adapter engineered for DC to 2.5 GHz applications, delivering stable performance with 50 Ω impedance and VSWR ≤1.22 (≥20 dB return loss). Insertion loss remains minimal at ≤0.1 × √F (GHz) dB, while insulation resistance reaches ≥5 GΩ for superior reliability. The screw-lock coupling mechanism ensures secure engagement, and mechanical endurance supports ≥500 mating cycles on the BNC side and ≥300 on the FME side.Constructed with premium materials, the BNC center contact is beryllium copper with gold plating over a nickel-phosphorus underlayer, while the FME center contact uses brass with identical plating structure. Both bodies are brass with copper-tin-zinc alloy finish, and PTFE insulators provide excellent dielectric stability. The adapter withstands temperatures from -65°C to +165°C and offers strong corrosion resistance for demanding environments.
ROSNOL combines exceptional quality with competitive pricing, making these RF components an ideal alternative to leading European and American brands. All products are manufactured under ISO 9001-certified processes and fully comply with RoHS and REACH standards. Customization services for plating, materials, and mechanical design are available to meet specialized interconnect requirements.
