Professional Industry Advantages
-
High-Fidelity Signal Integrity: Specifically engineered for high-performance signal transmission. With an exceptionally low attenuation rate (only 1.70 dB/m at 1 GHz) and stable 50 Ohm impedance, it ensures high-fidelity signal delivery across critical frequency bands up to 10 Gigahertz.
-
Superior Electromagnetic Protection: The high-density braided shield provides at least 85-95 percent coverage, offering exceptional immunity against external Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), which is essential for medical imaging and communication infrastructures.
-
Premium Fluoropolymer Construction: Utilizing high-grade FEP (Fluorinated Ethylene Propylene) for both insulation and the outer jacket ensures the cable remains chemically inert, moisture-proof, and thermally stable across a wide temperature spectrum from -55 degrees Celsius up to +125 degrees Celsius.
-
Optimized Micro-miniature Profile: With an outside diameter of only 1.37 mm, this cable supports high-density integration in restricted spaces such as robotic medical arms, advanced micro-miniature connectors, and compact military electronic modules.
-
High-Voltage Reliability: Rated for 1000 Volts maximum operating voltage, this series provides a significantly higher safety margin compared to standard micro-coaxial signal cables, ensuring absolute reliability in mission-critical industrial applications.
