The Cobalt Series of dry-mate underwater connectors and cables from Blue Trail Engineering sets a new standard for miniature 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 uw connectors carry up to 12 amps on each of 3 pins, 20 amps on each of 4 pins, or 5 amps on each of 6 pins. Connector shells are keyed and feature a scoop-proof design, allowing them to be mated blind with no possibility of pin damage.
Cobalt Series cables feature a simple, robust seal between the cable jacket and connector shell that eliminates the need for overmolding. A second hermetic seal between the connector pins and the connector shell provides redundancy. Because Cobalt connectors do not require overmolding, they cost less than traditional molded cables and connectors and eliminate the 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.
Cobalt cables are available with 3, 4, 6 or 8 conductors, and in a standard 1-meter length or custom lengths from 0.6 to 2.0 meters. (Contact Marine Distribution & Consulting for non-standard lengths) Cables are available in various end termination configurations:
- Both ends terminated with Cobalt connectors
- One end terminated with Cobalt connector, the other end unterminated
- One end terminated with Cobalt connector, the other end terminated with Blue Trail Engineering Simple Penetrator
COBALT CABLE MUST BE USED WITH COBALT BULKHEAD CONNECTOR (sold separately). 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 enclosures, thrusters, lights, grippers, and other accessories.
