Blue Trail Engineering
Subsea Connectors and Servos
robust miniature subsea connectors and servos
Blue Trail Engineering develops waterproof servos, electrical connectors, and thrusters that meet rigorous technical specifications while still fitting the budgets of startups, research groups, and university robotics programs.

Cobalt Series Underwater Connectors
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 connectors can handle high currents (up to 20 amps on the 4-
conductor version). Connector shells are keyed and feature a scoop-proof design, allowing
them to be mated blind with no possibility of pin damage.

Underwater Servos
Underwater servo at a fraction of the size and cost of other subsea actuators. Ideal for Autonomous Surface Vehicles as well as Remotely Operated Vehicles, provides reliable, long-term actuation at depths up to 100 meters.
