The zinc die-cast body with nickel finish holds up to the crimp cycle without cracking. Rated for 500 mating cycles, so it's built for test leads or equipment that gets connected and disconnected regularly. ## Temperature and Build Quality That covers outdoor enclosures, unheated equipment rooms, and industrial floor conditions. The silver housing color is standard for nickel-plated BNCs — easy to spot on a crowded patch panel.","metaTitle":"31-5800 BNC Plug, 50 Ohm, 4 GHz, RG-58, Crimp Termination","metaDescription":"31-5800 Amphenol RF BNC plug, male pin, 50 Ohm, 4 GHz max, for RG-58 plenum & Belden 88240.
