DNC-2076 Underwater 3G-SDI Bulkhead Connector
Professional Waterproof M16 Long Thread 3G-SDI Bulkhead Connector for Underwater HD Video Transmission Systems
The DNC-2076 is a professional underwater 3G-SDI bulkhead connector designed for transmitting stable 1080p60 HD video signals through underwater housings and professional marine video systems.
Built for underwater broadcast, cinematography, telemetry, inspection, and scientific applications, the DNC-2076 provides reliable long-distance SDI signal transmission using a professional waterproof bulkhead design with locking SDI connectivity.
The connector features an M16x1 long thread configuration compatible with underwater housings from manufacturers such as Salty, Aquatica, and Aquatech.
Why Choose 3G-SDI Underwater?
Unlike HDMI systems, 3G-SDI technology is designed for professional long-distance video transmission with improved signal stability, secure locking BNC connectors, lower signal loss, and higher reliability in demanding underwater environments.
Diagram A — How It Works
The DNC-2076 bulkhead connector creates a waterproof SDI pass-through from an underwater camera housing to a Dive And See SDI cable such as DNC-1062, allowing 1080p60 HD video to reach surface monitors, recorders, and broadcast equipment.
