Description
FME Plug (Male) to SMA Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-E1A25A/14-94 is a precision-engineered RF adapter designed for reliable performance in DC to 2.5 GHz applications. It offers a 50 Ω impedance, insulation resistance ≥5 GΩ, and center contact resistance as low as 3 mΩ on the SMA side. The adapter supports a test voltage of 1000 V rms and a working voltage of 480 V rms, with coupling achieved through a secure screw-lock mechanism. Mechanical durability ensures ≥500 mating cycles on the SMA side and ≥300 on the FME side, with torque ratings up to 2 Nm for FME and 1.7 Nm for SMA.Constructed with high-quality materials, the center contact on the FME side is brass with gold plating over a non-magnetic nickel-phosphorus underlayer, while the SMA side uses beryllium copper with the same 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 superior corrosion resistance.
ROSNOL’s RF components combine premium quality with cost-effective pricing, making them an ideal alternative to leading European and American brands. All products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH standards. Customization services for plating, materials, and mechanical design are available to meet specialized interconnect requirements.
