Notes (Overall)
Notes:
Pair jackets and shields are bonded so both strip simultaneously with automatic stripping equipment. Datalene® insulation
features include low dielectric constant and a dissipation factor for high-speed, low-distortion data handling. Physical
properties include good crush resistance and light weight.
