The 75 Ohm impedance tells you this is a video-grade connector, sized for composite video, CCTV, and broadcast baseband signal paths where the characteristic impedance of the cable and connector must match to avoid reflections. The center contact is gold-plated phosphor bronze, which keeps contact resistance stable across the rated 500 mating cycles — important for patch panels and field-service connections where the connector sees regular reconnects. The body is a nickel-plated zinc alloy, giving it the standard BNC mechanical feel and RF shielding performance. ## Mating and Termination The bayonet lock mates with any standard BNC plug — the quarter-turn coupling provides positive retention under vibration while staying field-serviceable. Termination is through-hole solder for both the center contact and the shield, which gives a reliable solder joint on the PCB for the signal and ground paths. The dielectric is polyethylene (PE), the standard BNC insulator material that maintains the 75 Ohm impedance through the connector body.","metaTitle":"Molex 73171 BNC Jack, 75 Ohm, 0731711900","metaDescription":"Molex 0731711900 BNC jack, 75 Ohm impedance, bayonet lock, gold-plated center contact, 500 mating cycles.
