Product details

The 031-70567-12G: The 12 GHz max frequency rating puts this well above typical 75 Ohm BNCs (which usually top out around 1-4 GHz), so it handles uncompressed HD-SDI and 4K video links without the roll-off you get from a standard 50 Ohm BNC on a 75 Ohm line.

Cable Group and Termination — Keeping the 75 Ohm Path Clean

This jack is specified for Belden 4505R cable — a 75 Ohm precision video coax. The kit includes the ferrule and contact, so you are not hunting for the right crimp parts separately.

What the 12 GHz Rating Means for Your Signal Chain

This BNC jack is rated to 12 GHz, with a nickel-plated brass body and gold centre contact.

Frequently asked questions
