Rated to 200 MHz, this connector is built for analog video bandwidths and low-frequency data — not for high-rate digital or RF test gear that demands a 50 Ohm path. Silver plating on both the body and center contact keeps contact resistance low across 1000 mating cycles, which is a solid life for a field-swapped connector. Operating temperature spans -30°C to 60°C, covering indoor equipment rooms and outdoor enclosures in temperate climates. The PTFE dielectric holds stable impedance across that range without significant phase shift. ## Last Buy — Sourcing Reality The BNC(75)-P-59/U(40) is on Last Buy status. That means the manufacturer has stopped regular production and is fulfilling final orders through a last-time-buy window. Once that window closes, the only channel will be surplus and broker stock carrying whatever date codes remain. This is not an NRND — it is a formal end-of-life signal with a finite supply window. ## Mating and Termination Check Mates with any standard 75 Ohm BNC jack (female) of the same impedance class. The bayonet lock engages with the two studs on the jack body — no threads, no torque spec. Termination is solder for the center conductor and a clamp for the braid: strip the RG-59 per the manufacturer's strip dimension, tin the center conductor, solder into the pin, then slide the braid over the clamp ferrule and tighten the nut. No crimp tool needed, which makes field repair straightforward. The shield termination clamp handles the braid directly — no separate ferrule or heat-shrink required for the connection, though a boot over the cable entry is normal for strain relief in a pulled run.","metaTitle":"BNC(75)-P-59/U(40) BNC Plug, 75 Ohm, RG-59, Last Buy","metaDescription":"BNC(75)-P-59/U(40) BNC plug, 75 Ohm impedance, RG-59 cable, silver-plated brass, 200 MHz, 1000 mating cycles.
