Cobalt Series dry-mate underwater connectors and cables from Blue Trail Engineering set a new standard for small waterproof connectors. Cobalt connectors offer the same reliability as larger subsea connectors, but at a fraction of the cost. With 316 stainless steel shells and PEEK inserts, they withstand long-term use in seawater at depths up to 600 meters. In spite of their compact size, Cobalt connectors can handle high currents. Connector shells are keyed and feature a scoop-proof design, allowing them to be mated blind with no possibility of pin damage.
Cobalt 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 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.
Perfect for space-limited applications, Cobalt connectors take up a fraction of the volume of the industry-standard Micro-Circular connectors.
Stock connectors and cables typically ship in 2-3 days. Custom items or large orders ship in 1-2 weeks.
The Cobalt bulkhead connector fits in the same 10-mm hole as Blue Robotics penetrators, making quick-connect and quick-disconnect possible with Blue Robotics thrusters, tethers, enclosures, lights, grippers, and other accessories. A Cable Termination Kit allows the user to retrofit an existing Blue Robotics thruster with a Cobalt connector.
The Cobalt bulkhead connector is available in 3-pin, 3-pin power, 4-pin, 6-pin, 6-pin hybrid, and 8-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. COBALT BULKHEAD CONNECTOR MUST BE USED WITH COBALT CABLE OR CABLE TERMINATION KIT (sold separately).
