01 / CONFIGURATION DIRECTIONS
Select a configuration from the application boundaries
These configurations establish a practical discussion starting point. The final product requires a controlled specification based on interface, length, installation and validation conditions.
Wide-temperature fluoropolymer
Maintains differential geometry, dielectric withstand and shield continuity from −65 to +200 °C.
Flexible polyurethane
For softer equipment routing; temperature, flame and fluid compatibility are confirmed by configuration.
Match a solution direction to the link target
Solution codes support early technical discussions by aligning protocol, construction, link boundaries and application in one view.
