DNC-2178 Underwater Ethernet + Power Bulkhead Connector 7/16-20 for Remote Camera Control
Professional underwater Ethernet and power bulkhead connector designed for equipment that uses the specialized 7/16-20 threaded port. The DNC-2178 combines Cat6 Ethernet communication and two 18 AWG power conductors through one compact underwater housing penetration.
Overview
Professional Ethernet + Power Through a Single 7/16-20 Port
The DNC-2178 is a professional underwater bulkhead connector designed for systems that use the 7/16-20 threaded interface. This thread is not commonly used on consumer products. It is often found on professional underwater equipment, scientific instruments, industrial imaging systems, OEM platforms, and specialized camera housings.
The DNC-2178 combines Cat6 Ethernet communication and two 18 AWG power conductors into a single connector, allowing both data transmission and power delivery through one compact housing port. This reduces the need for multiple penetrations and simplifies system integration for underwater control, monitoring, and imaging applications.
Diagram A — How DNC-2178 Works
This diagram shows how the DNC-2178 passes Ethernet data and power through one professional 7/16-20 port, using a compatible Ethernet + power cable and an included RJ45 termination connector.
Key Benefits
- Designed for professional 7/16-20 threaded ports used on many specialized underwater systems.
- Ethernet + power through one connector for simplified installation and fewer housing penetrations.
- Cat6 Ethernet support for network communication, remote control, monitoring, and data transfer.
- Two 18 AWG power wires for delivering power from the surface to underwater equipment.
- Marine brass construction for harsh underwater and saltwater environments.
- Gold-plated brass contacts for reliable signal transmission and corrosion resistance.
- Water Block Technology helps protect the housing side and maintain vacuum integrity.
- Depth rated to 100 meters / 145 PSI for professional underwater applications.
- RJ45 termination connector included for installation after the wires pass through the compact port.
- Compatible with DNC-1121 Ethernet + Power cable and custom Dive And See Ethernet systems.
Why It Is Different
Many underwater connectors are designed around M16 or M24 ports commonly found on camera housings. The DNC-2178 was developed specifically for equipment that uses the more specialized 7/16-20 professional threaded interface.
This makes it valuable for professional imaging systems, scientific instruments, industrial inspection platforms, underwater monitoring stations, OEM devices, and other systems where a compact 7/16-20 port is already part of the equipment design.
Designed for Small 7/16-20 Ports
One of the unique advantages of the DNC-2178 is its ability to fit through compact 7/16-20 threaded ports commonly found on professional underwater equipment.
Because the opening is too small to pass a fully assembled RJ45 Ethernet connector through the housing wall, the Ethernet conductors are routed through the bulkhead first. After installation, the user terminates the Ethernet connection using the RJ45 connector included with the product.
This approach allows Cat6 Ethernet communication and two 18 AWG power conductors to pass through a compact professional 7/16-20 port while maintaining the smallest possible connector footprint.
Compatibility Ecosystem
The DNC-2178 is part of the Dive And See underwater Ethernet and Ethernet + Power ecosystem. It is commonly used with compatible cables, bulkhead connectors, and custom control systems.
Water Block Technology
The DNC-2178 includes a built-in Water Block System that helps maintain housing vacuum integrity and provides additional protection against accidental water ingress. This is especially important for underwater housings using vacuum systems such as AirLock or similar pressure-monitoring systems.
Compatible Cable — DNC-1121
The DNC-2178 is commonly used with the DNC-1121 waterproof Ethernet + power cable for surface-to-underwater control, data transmission, and power delivery.

Tightening Warning Before Submersion
Before placing the housing underwater, always verify that the external cable coupling nut is fully tightened by hand. Do not use pliers or tools. The connector and cable should feel like one solid assembly with no looseness or movement.
An incorrectly tightened underwater connector can cause water ingress, flooding, or permanent equipment damage. Always inspect the connector, O-rings, cable connection, and sealing surfaces before submerging the system.

FAQ
What is the main advantage of the DNC-2178?
The main advantage is that it combines Cat6 Ethernet and two 18 AWG power conductors through a compact professional 7/16-20 threaded port.
Why is the 7/16-20 thread important?
The 7/16-20 thread is used on many professional underwater devices, scientific instruments, industrial platforms, and OEM systems. It is less common on consumer camera housings, which makes the DNC-2178 a specialized solution for professional equipment.
Why is the RJ45 connector supplied separately?
The 7/16-20 opening is too small to allow a pre-assembled RJ45 connector to pass through the housing. The Ethernet conductors are routed first, and the included RJ45 connector is installed afterward.
Can the DNC-2178 provide both Ethernet and power?
Yes. It provides Cat6 Ethernet communication and two 18 AWG power wires in one bulkhead connector assembly.
What cable is commonly used with the DNC-2178?
The DNC-1121 waterproof Ethernet + power cable is commonly used with the DNC-2178 for surface-to-underwater camera control, monitoring, and power delivery.
What depth is it rated for?
The DNC-2178 is rated to 100 meters / 145 PSI.
