Description
FME Plug (Male) to BNC Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-E1B25A/13-93 is a high-performance RF adapter designed for DC to 2.5 GHz applications, ensuring stable signal integrity 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 is ≥5 GΩ for superior reliability. The adapter supports robust mechanical endurance with ≥500 mating cycles on the BNC side and ≥300 on the FME side, complemented by a secure screw-lock coupling mechanism and recommended torque of ≤2 Nm.Engineered 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 nickel 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 delivers top-tier RF components at competitive pricing, making them 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.
