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.
Silver/nickel copper braid
Shielding, grounding and mechanical reinforcement.
ePTFE over metal braid
Combines outer protection with internal EMI suppression.
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.

Example sizes
Temperature limits depend on ePTFE, silver-plated copper, nickel-plated copper or composite construction; the dynamic-flex minimum is −100 °C.
Technical referenceValues are confirmed against category, gauge, length and termination
03 / TYPICAL CONSTRUCTION
From functional core to terminated interface
Protected cable
Original diameter, temperature, motion and sensitive surfaces are confirmed.
Isolation buffer
Reduces imprint, friction and thermal effects from protection materials.
Main protection
Extruded jacket, ePTFE, fiber or metal braid provides the defense.
Closure and branch
Sleeving, wrapping, tying or custom branching supports installation and service.
End restraint
Rings, backshells or strain relief control fray and edge wear.
