Product Description
12G-SDI BNC to HD-BNC Cable – Belden 4505R RG59
The AV-Cables 12G-SDI BNC to HD-BNC cable is built for professional broadcast, live production and 4K UHD video systems that require a standard BNC connection on one end and a compact high-density HD-BNC connection on the other.
Built with Belden 4505R 75-ohm RG59 coaxial cable and precision 12G-rated connectors, this assembly is designed to support 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI and SD-SDI signal formats. It is an excellent choice for cameras, switchers, routers, monitors, patch systems and other professional video equipment using HD-BNC connectivity.
Each cable is hand-assembled in the USA and individually tested for reliable performance in professional video environments.
BNC Male to HD-BNC Male Configuration
This cable features a 75-ohm standard BNC male connector on one end and a 75-ohm HD-BNC male connector on the other.
The HD-BNC connector provides the same professional 75-ohm performance required for SDI video while using a much smaller connector footprint. This makes it ideal for high-density broadcast equipment, routers, switchers and rack-mounted systems where panel space is limited.

Why Use HD-BNC?
HD-BNC connectors are designed for high-density professional video equipment where a traditional BNC connector would consume too much panel space. They maintain professional 75-ohm coaxial performance while allowing significantly more SDI connections to be installed in the same rack or equipment footprint.
This BNC to HD-BNC cable provides a clean way to connect traditional BNC-based equipment and cabling to newer high-density HD-BNC systems without relying on rigid adapters.
