These underwater connectors from Blue Trail Engineering are a low-cost and low- profile way to waterproof your connections quickly. And the best part: QUICK RELEASE!
With Cobalt connectors, the pins/sockets are press-fit into a PEEK plastic connector core which is then press-fit into the connector shell. These dry-mateable electrical connectors mean devices can be quickly removed from a waterproof enclosure without having to open the enclosure and disconnect wiring.
Similarly, Cobalt pre-made cables utilise a robust mechanical seal between the cable jacket and the connector shell. The cable jacket consists of high-quality polyurethane tubing with a smooth inner wall, which fits over a barbed shank on the connector shell. Cobalt connectors are more simple and more reliable than potted/moulded connectors.
