DNC-2190 M16 SDI / Power Bulkhead Connector with Interchangeable 2-Pin LEMO or D-Tap
The DNC-2190 is a professional panel-mount SDI and power bulkhead connector designed for underwater housings, splash bags, remote camera systems, inspection setups, ROV platforms, marine research systems, broadcast rigs, and custom production builds.
It combines 3G-SDI video transmission with flexible external power routing in one compact M16 panel-mount solution, allowing you to build clean, reliable, and serviceable camera systems in demanding environments.
The connector features an M16x1 extended thread with security nut, making it ideal for thicker walls, splash bag panels, and custom aluminum or composite housings. It is designed for users who need a dependable way to pass both SDI video and power through a housing wall or panel without compromising serviceability.
The power side supports interchangeable configurations, including 2-pin LEMO 0B (ARRI-style) and D-Tap, giving flexibility across different camera systems, batteries, transmitters, monitors, and field workflows.
Key Benefits
- SDI video and power in one compact bulkhead connector
- Interchangeable 2-pin LEMO or D-Tap power options
- Extended M16x1 thread for thick panels and custom builds
- Security nut included for reliable installation
- 3G-SDI support up to 1080p60
- Service-friendly removable power lead design
- Built for underwater, wet, industrial, and mobile production environments
Why This Product Is Different
The DNC-2190 is designed for real-world production and engineering workflows where both video and power must pass through a housing wall cleanly, safely, and reliably.
Unlike a simple SDI feed-through, this solution gives you a more practical system design:
- Run SDI video (BNC) to the surface or external equipment
- Power your camera or device through LEMO or D-Tap
- Switch between different power ecosystems without redesigning the whole setup
- Use one robust connector format across multiple builds and applications
This makes the DNC-2190 ideal for professionals who need equipment that works reliably not just in the workshop, but also in the field, offshore, on location, or far from immediate technical support.

Flexible Power Configuration
The DNC-2190 can be configured with a 2-pin LEMO 0B male connector, a power style commonly used in professional camera and accessory workflows. This makes it useful for systems built around cameras, wireless transmitters, monitors, recorders, and other equipment that rely on compact professional power connections.
For additional flexibility, an optional short adapter cable can be supplied with a Female 2-pin LEMO 0B connector on one end and a Male D-Tap on the other. This gives the user the option to power the same system either from a camera-side 2-pin output or from a D-Tap battery source such as a V-Mount or Gold Mount setup.
This interchangeable approach is especially useful for operators who work across multiple cameras or production environments and want one dependable connector system instead of multiple one-off solutions.

Built for Real-World Reliability
Professional users often travel far from home and work in harsh places where equipment simply must perform. In underwater production, offshore operations, scientific expeditions, remote inspections, and cold-weather deployments, there may be no easy replacement and no second chance once the system is assembled.
That is why the DNC-2190 is positioned not as a generic connector, but as a reliable field-ready component for serious working systems. The goal is simple: when the customer opens the case, connects the cables, and powers up the rig, the system should work with confidence and without unwanted surprises.
Important Tightening Warning
Before submerging or using in wet conditions, verify that the coupling nut is fully tightened by hand. Do not use pliers or tools. After tightening, the connection must feel solid as a single unit. When moving the cable, there should be no movement or play in the connector or connection. Improper tightening may result in flooding or equipment damage.
