With outstanding electrical properties, this cable ensures stable signal transmission with minimal losses and high shielding effectiveness, even in demanding environments.
Sold per meter, allowing you to purchase the exact length needed for your project without unnecessary extra costs.
Construction and Materials
✅ Solid Core Conductor for Low Losses
The center conductor is made of silver-plated copper, providing excellent electrical conductivity and minimal signal loss at high frequencies. Silver plating enhances the skin effect, which is critical for minimizing attenuation in RF applications.
✅ PTFE Dielectric for Signal Stability
The insulating layer is polytetrafluoroethylene (PTFE), known for its low dielectric constant and excellent signal stability across a wide frequency range.
✅ Copper Tube Shield for Maximum Protection
The outer conductor is a solid copper tube, providing up to 100 dB shielding effectiveness, minimizing electromagnetic interference (EMI), and ensuring clean and stable signal transmission.
✅ FEP Jacket for Environmental Resistance
The cable is protected by a fluorinated ethylene propylene (FEP) jacket, offering high resistance to temperature extremes, mechanical stress, and chemical exposure. The blue color simplifies identification during installation.
