S_04272_B - Low-Loss RF Coaxial Cable S_04272_B – 50 Ohm, 18 GHz, ø5.5 mm, PE Jacket

HUBER+SUHNER S_04272_B Low-Loss Coaxial Cable

The S_04272_B is a high-performance, low-loss RF coaxial cable designed for demanding applications up to 18 GHz. Engineered as a superior alternative to standard SPUMA cables, it offers excellent electrical and mechanical properties for precision signal transmission in RF and microwave systems.

With a 50 Ohm impedance and robust shielding (90 dB screening effectiveness), this cable ensures minimal signal attenuation and high reliability across a wide frequency range. Its silver-plated copper conductor and foamed polyethylene dielectric deliver optimal signal velocity (82%) and low capacitance (82 pF/m), making it ideal for high-frequency data, radar, satellite, and test & measurement environments.

The S_04272_B features a durable PE jacket (RAL 5014 blue) with a compact 5.5 mm diameter, suitable for installations where space and flexibility matter. It supports static bending down to 25 mm and repeated bending at 90 mm, ensuring long-term mechanical resilience.
