Product details

The 031-70558-12G: At 75 Ohm it is the standard impedance for video and broadcast video distribution, not the 50 Ohm common in telecom and test equipment. The 12 GHz frequency ceiling is high for a 75 Ohm BNC — most video BNCs top out around 4 GHz — so this plug handles HD-SDI and 12G-SDI signal paths without a bump at the connector. The bayonet lock is the standard BNC quick-twist; the plug ships as three pieces — connector body, crimp contact, and ferrule — ready to terminate onto the cable.

Frequently asked questions

Is 031-70558-12G 50 or 75 Ohm?

That is the standard impedance for broadcast video and HD-SDI signal paths, not the 50 Ohm used in RF test equipment and telecom.

What cable is compatible with 031-70558-12G?

It is designed for Belden 4694P cable. The crimp ferrule and center contact are sized to that cable's dimensions; using a different 75 Ohm coax may not produce a reliable termination or consistent impedance through the connector.
