DNC-2089 Underwater M16 Ethernet + Power Bulkhead Connector - Cat6 with 18 AWG Power
DNC-2089 is an underwater M16 bulkhead connector designed to pass both Cat6 Ethernet data and separate power conductors through a sealed underwater housing port.
This connector is useful for underwater camera systems, live streaming, remote camera control, inspection systems, and custom marine electronics where Ethernet communication and surface power are required in one compact bulkhead assembly.
Overview
DNC-2089 combines Cat6 Ethernet support with two 18 AWG power wires. This allows an operator to control compatible underwater equipment over Ethernet while also providing power from the surface through the same connector system.
The connector fits an M16x1 threaded port or a 0.625 inch / 16mm housing hole, making it suitable for custom underwater housings, pressure enclosures, Mantis Sub-style systems, and marine camera installations.

- Custom Ethernet + power pass-through applications
- Underwater lights, accessories, and low-voltage equipment depending on system design
Ethernet + Power Design
The DNC-2089 is built for systems where Ethernet data and power need to pass through the same housing wall. Cat6 Ethernet can be used for camera control, data transfer, live monitoring, or network communication, while the two 18 AWG wires provide a separate power path.
This is different from Ethernet-only connectors because DNC-2089 gives the system designer both network communication and dedicated power conductors in one bulkhead solution.
Water Block System
The DNC-2089 underwater bulkhead connector includes a built-in water block.
The water block helps maintain vacuum inside the housing when using an AirLock vacuum system. It also adds protection against water penetration if the external cable or external connector connection becomes damaged.
