All of our connectors are designed to be waterproof up to 600 meters in the open-face (unmated) condition, but due to manufacturing tolerances we do not guarantee an open-face depth rating. Exercise extreme caution when using any voltage above 30 volts, especially near water, as these connectors have metal shells and semi-exposed contacts.ĭo the connectors have an open-face depth rating? No. This voltage rating is based on the creepage distance between pins/sockets in our connectors. How do you determine the current rating for your connectors? We base the current rating of our connectors on the manufacturer's rating for the electrical contacts (pins and sockets) used in the connectors.Ĭan Cobalt connectors be used for 400-volt systems? We have not tested Cobalt cables and connectors to 400 volts, and we do not recommend using them at any voltage above the rated voltage of 100 VRMS / 150 VDC. Same thing here: it both protects and ensures waterproofness.
MOLEX CONNECTOR KIT INSTALL
This protects the bulkhead connector from contamination and ensures that it will be waterproof to 600 meters.ĭummy Cap: Install the Dummy Cap on the end of an unmated cable. Note that the Removable Locking Sleeve only works on the "regular" size of cable termination kit, not on the "large" size.ĭummy Plug: Insert the Dummy Plug into a bulkhead connector in place of a cable. This is similar to the locking sleeves found on other subsea connectors: it uses an internal retaining ring (actually just a plastic split washer) that is installed after you slip the locking sleeve over the connector.
In this case, just use a Removable Locking Sleeve.
But sometimes you need to be able to remove the locking sleeve, for instance if you need to fish the cable through a small hole. Removable Locking Sleeve: The standard locking sleeve that comes with our cables and termination kits is held captive on the cable (you can't remove it or re-install it). The Cobalt bulkhead connectors also have M10 threaded shanks instead of 7/16-20 threaded shanks, making them compatible with Blue Robotics products.Ĭobalt connectors and cables are available in 3-pin, 4-pin, 6-pin and 8-pin versions. This makes it easy to integrate them into smaller marine robotics projects. Small size: Cobalt connectors are significantly smaller than other subsea connectors, both in diameter and length. Low cost: Because of their unique design, the manufacturing of Cobalt connectors is relatively quick and does not require special equipment or tightly-controlled potting/overmolding processes, thus reducing cost.
Custom items or large orders may take a week or two, but we are striving to cut the lead time as much as possible. Immediate availability: We ship the vast majority of our orders within 2-3 days. For these situations we offer a cable termination kit that does require a simple potting operation, but even then the potting can be done by an amateur without the need for a mold or any special equipment. In some cases, customers want to put a Cobalt connector on their own cable. This makes Cobalt connectors more simple and more reliable than potted/molded connectors. The cable jacket consists of high-quality polyurethane tubing with a smooth inner wall, which fits over a barbed shank on the connector shell. Similarly, our Cobalt cables utilize a robust mechanical seal between the cable jacket and the connector shell. In Cobalt connectors, however, the pins/sockets are press-fit into a PEEK plastic connector core which is then press-fit into the connector shell. No potting or overmolding: Most other subsea connectors use potting or overmolding to make the waterproof seal between the connector shell and the electrical contacts.
