7-core control cable with 2 power cores, 9 conductors total, PUR jacket. Underwater composite cable for ROV multi-channel control and power in one run.
The 7+2 core underwater composite cable provides an additional signal channel over the 6+2 design, accommodating ROV systems with seven independent control or sensor signal channels alongside dedicated power conductors. The extra core is typically used for a spare/redundant signal path, an additional sensor input, or a dedicated ground return, depending on the ROV system architecture.

Common uses for the extra core include: spare/redundant signal path, dedicated RS-485 ground reference, additional analog sensor input (4-20mA), or a separate lighting dimmer control channel. The function is defined by the ROV system integrator.
The outer diameter depends on the conductor sizes chosen for control and power cores. A typical 7x0.5mm² + 2x1.5mm² configuration results in approximately 8--10 mm OD. Contact us with your conductor specification for an accurate OD calculation.
