The BNC7T-J-P-GN-ST-EM1: This female socket connector is rated to 12 GHz, covering 4K and 12G-SDI signal paths without the roll-off you'd see from a basic 3 GHz video BNC. That means no separate hardware order for the panel-mount installation — the lockwasher and nut are in the bag. The body is machined brass with a nickel finish, giving a consistent silver appearance across the panel.
Mounting Options — Board Edge or Bulkhead
This jack supports two mounting methods: board edge, end launch for PCB integration, or panel mount through a bulkhead with the front-side nut. For panel mount, the bulkhead thread accepts the included nut, and the lockwasher prevents loosening under vibration. The shield termination is solder, so the ground connection is solid at the board or the chassis.
What the 12 GHz and 75 Ohm Ratings Mean for Your Signal Chain
The 12 GHz frequency ceiling is well above the 3 GHz typical of standard-definition video BNCs — this connector handles 12G-SDI (12 Gbps) uncompressed video without the insertion loss spike that kills signal integrity at the upper band edge. If your system is 75 Ohm — and most video, cable TV, and telecom distribution is — this is the correct impedance. The PTFE dielectric holds stable dielectric constant across that range, so the impedance stays within tolerance.
The base product number is BNC7T-J, so variants with different plating or packaging share the same interface dimensions.
