Brief Description
DNC-2099 was developed for custom underwater applications where both Ethernet communication and power are required through the same bulkhead connection.
The main advantage of this connector is the detachable XLR power connection. It allows the system to receive power from the surface while also supporting Ethernet control or data transmission for compatible cameras and underwater electronics.
The connector uses a Cat6 Ethernet connection and an M16x1 thread. Thread length is approximately 0.5 inch.
Water Block
The DNC-2099 underwater bulkhead connector comes with a built-in water block.
The water block helps keep vacuum inside the housing when using an AirLock vacuum system. It also helps protect the housing against water penetration if the external cable or the external connector connection becomes damaged.
Options
Custom cable length and different connector configurations may be available for custom underwater power and Ethernet systems.

Compatibility
DNC-2099 is compatible with the DNC-1121 waterproof Ethernet + power cable assembly.
