Professional Industry Advantages
-
Ultimate Nano-Scale Profile: With a finished outside diameter of only 0.33 mm, this is the most compact 50 Ohm high-frequency coaxial cable in the series. It is specifically engineered for integration into the world’s smallest medical robots and micro-sensors where space is the primary design constraint.
-
Specialized Silver-plated Copper Alloy: The AWG 42 core utilizes a proprietary high-strength copper alloy plated with high-purity silver. This ensures superior electrical conductivity while maintaining the mechanical resilience required for micro-miniature assemblies.
-
Premium PFA Dielectric Performance: Utilizing Perfluoroalkoxy (PFA) for both insulation and the outer jacket ensures an exceptionally low dielectric constant and stable performance even at its ultra-thin wall thickness, preserving high-speed signal integrity.
-
Optimized Spiral Shielding: The spiral-wrapped shielding design provides 100 percent electromagnetic interference (EMI) isolation while maintaining the extreme flexibility required for articulated surgical instruments and rotating aerospace components.
-
Articulated Flexibility: The 7-strand conductor construction (7 x 0.025 mm) is precision-engineered for repeated movement and fatigue resistance in high-density multi-channel wiring harnesses.
