The nickel-plated brass body and PTFE dielectric maintain consistent impedance through the crimp zone. When terminating, confirm the cable jacket diameter matches the ferrule bore for the specific RG-58 or RG-141 variant — the kit includes one ferrule, so the cable group compatibility is fixed at ordering. ## Kit Contents and Termination The 031-327-RFX ships as a three-piece kit: one BNC jack body, one centre contact, and one ferrule. The bayonet lock provides positive retention without tools — a quarter-turn mates or unmates the pair. With 500 mating cycles on the gold-plated contact, this connector is suited for test-equipment patch panels or field-reconnect harnesses where periodic disconnection is expected.","metaTitle":"031-327-RFX BNC Jack, 50 Ohm, 4 GHz, Crimp Termination, NRND","metaDescription":"031-327-RFX BNC jack, 50 Ohm, 4 GHz max, crimp termination for RG-58/RG-141.
