The Cobalt 14 series of underwater connectors expands the Cobalt line with a larger shell size, offering higher current-carrying capability while delivering the same reliability and affordability that has made the Cobalt line so popular.

With 316 stainless steel shells and PEEK inserts, they withstand long-term use in seawater at depths up to 600 meters. Connector shells are keyed and feature a scoop-proof design, allowing them to be mated blind with no possibility of pin damage.

Cobalt 14 connectors achieve a hermetic seal without the need for potting or overmolding, making them more affordable than traditional molded connectors. The electrical contacts are pressed into a machined PEEK insert, which is in turn pressed into the stainless steel connector shell.

In addition to reducing cost, the unique design of Cobalt 14 connectors increases their reliability. Without a bonded rubber overmold, there is no danger of leakage due to cathodic delamination. A simple, proven O-ring seal between the male and female connectors makes Cobalt connectors both easier to use and more reliable than wet-mate connectors.

Stock connectors and cables typically ship in 2-3 days. Custom items or large orders ship in 1-2 weeks.

The Cobalt 14 bulkhead connector fits in the same hole as the 14-mm Blue Robotics WetLink penetrator, making quick-connect and quick-disconnect possible with the Blue Robotics T500 thruster. A Cable Termination Kit allows the user to retrofit an existing Blue Robotics thruster with a Cobalt connector.

The Cobalt 14 bulkhead connector is available in 3-pin, 4-pin, 10-pin Hybrid, and 19-pin versions. It can be installed in the wall of any enclosure, provided that the enclosure has a smooth outer surface to seal against the connector’s O ring.
