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.","metaTitle":"Amphenol RF 031-70558-12G BNC Plug, 75 Ohm, 12 GHz","metaDescription":"Amphenol RF 031-70558-12G BNC plug, male pin, 75 Ohm impedance, 12 GHz max, for Belden 4694P cable.
