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.
28 AWG lightweight type
Reduces diameter and mass for dense routing.
Terminated assembly
Connector, length and shield grounding form the complete channel.
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.

Technical referenceValues are confirmed against category, gauge, length and termination
03 / TYPICAL CONSTRUCTION
From functional core to terminated interface
Space-grade conductor
Material, stranding and plating are selected for resistance, strength, flex and termination.
Low-outgassing insulation
Dielectric, thermal, vacuum-stability and processing requirements guide material selection.
Controlled functional unit
Single, twisted, shielded, coaxial or multicore signal geometry is formed.
Lightweight shield and cover
EMI, atomic oxygen, protection and mass are optimized together.
Termination and traceability
Connector, branch, strain relief, material lot and process records remain controlled.
