The Hirose BNC(75)-PR(6)-PC-12G is a 75 Ohm BNC jack, female socket, designed for the 12 GHz frequency ceiling that makes it suitable for 12G-SDI and other high-data-rate serial digital video paths. The 75 Ohm impedance is the standard for broadcast video infrastructure, and the 12 GHz max frequency means this connector handles 4K and 8K uncompressed video without choking the return loss at the upper band edge. The bayonet lock gives a positive, quarter-turn mate that stays put under cable strain — a half-turn loose on a 12G link and you're chasing sparkles on the monitor. The panel mount uses a flange with through-hole solder termination for the shield, and the center contact is solder-terminated as well. This is a one-port jack, so it's a single connection point on a bulkhead or chassis, not a feed-through.
Wiring and Termination: Solder Both Ends
There is no crimp option on this jack — it's a solder-only install. The PTFE dielectric handles soldering heat without melting or shifting, but take care not to overheat the center pin and wick solder into the dielectric interface, which will shift the impedance. The flange mount gives four screw holes for panel attachment; the through-hole shield tabs go into the PCB if you're board-mounting it, or you can solder a ground wire directly.
