Professional Industry Advantages
-
Advanced Hybrid Integration: This cable integrates three independent shielded 50 Ohm high-frequency units and one signal lead into a single 0.68 mm profile. This allows for simultaneous high-definition video data, feedback signals, and power/control delivery in ultra-slender surgical catheters or industrial probes.
-
Nano-Scale Precision Conductor: Utilizing a 7-strand silver-plated copper alloy (42 AWG) ensures both high-fidelity signal transmission and the mechanical strength required to withstand repetitive bending in articulated robotic systems.
-
Premium PFA Dielectric Matrix: All layers, from primary insulation to the outer jacket, utilize high-grade Perfluoroalkoxy (PFA). This ensures an exceptionally low dielectric constant for low-loss transmission and absolute resistance to chemicals and moisture.
-
Superior EMI Isolation: Each high-frequency sub-cable features its own independent silver-plated alloy spiral shield. This prevents internal crosstalk between cores and provides a 100 percent barrier against external electromagnetic interference, essential for precision medical diagnostics.
-
High-Density Packaging: With a total diameter of only 0.68 mm, this composite cable enables 4-channel functionality in spaces that typically only accommodate a single standard wire, facilitating the next generation of miniaturized medical and aerospace instrumentation.
