AWG 22/7 bare copper conductors for the mobile-use construction.
Aluminium-lined polyester foil and tinned copper braid screens.
7.8 ± 0.3 mm outer diameter and approximately 75.0 kg/km weight.
Match the cable to the movement pattern and the connector’s stranded-conductor termination. Use the listed laying radius of 10 times the overall diameter for installation planning. For guided drag-chain travel or torsional movement, compare the dedicated constructions linked below.

No. AWG 22/7 describes a seven-strand conductor. This cable has two insulated signal conductors forming one pair.
The outer sheath is PVC, with violet as the listed colour.
An aluminium-lined polyester foil and an overall tinned copper braid surround the pair assembly.
The operating temperature range is −20°C to +70°C.
This version uses AWG 22/7 conductors and a PVC sheath. The dedicated drag-chain version uses a different stranded conductor construction and a PUR sheath.
