It is part of the HD-BNC series, a higher-density variant of the standard BNC that maintains 75 Ohm impedance while extending the frequency range well beyond the typical BNC ceiling. ## Mounting and Termination — Board Edge or Panel This jack supports two mounting methods: board edge end launch for direct PCB attachment, or panel mount via the included bulkhead front-side nut. The bayonet lock provides quick connect/disconnect with positive retention, standard for BNC-style interfaces. Supplied as two pieces: the connector body and the bulkhead nut; plan for a lockwasher or sealing gasket separately if the application requires vibration resistance or environmental sealing. ## Why 75 Ohm and 18 GHz Matter for Your Signal Path Rated to 18 GHz, this HD-BNC variant supports signals beyond the typical BNC range. Both are 75 Ohm, 18 GHz, single-port jacks with bayonet lock and solder termination. The key difference: the 034-1140-12G adds an isolation feature and carries a nickel/gold body finish (housing color gold and silver) versus the all-gold finish of the 034-1018-12G. If your application requires electrical isolation between the connector body and the panel, the 034-1140-12G is the variant to evaluate. For a standard non-isolated install, the 034-1018-12G covers the same frequency and impedance requirements.","metaTitle":"034-1018-12G HD-BNC Jack, 75 Ohm, 18 GHz, Gold, Bulkhead","metaDescription":"034-1018-12G HD-BNC jack, 75 Ohm, rated to 18 GHz.
