Application fit

Is Wet-Mate Ethernet 8C Subsea Cable right for your machine?

Immersion & wet locations

Suitable

Longitudinal water-blocking compounds and high-pressure subsea PUR/PE jackets survive up to 600 bar (6,000 m) hydrostatic immersion.

Fixed installation

Suitable

Controlled 100 Ω Ethernet, 120 Ω RS-485 and 50/75 Ω coaxial impedance ensures low-attenuation telemetry across subsea arrays.

Free-hanging vertical run

Suitable

Stranded tinned copper conductors and braided shields tolerate ROV tether flexing, buoy moorings and subsea frame routing.

Offshore platform & shipboard deck trays

Suitable

NEK 606 MUD-resistant LSHF and UV-stabilized PUR jackets withstand offshore topside trays and wet deck splash zones.

Motorised monospiral reel

Not suitable

Unarmoured sensor bus and coax cables require strain relief and are not intended for unguided high-tension crane drums.
