The bayonet lock provides quick connect/disconnect with positive retention, and the nickel-plated brass body gives reliable shielding. This is a 75 Ohm variant, not the more common 50 Ohm BNC, so it's suited for video, broadcast, and broadband data applications where impedance matching to 75 Ohm cable is required. This plug is engineered for a specific cable group: AT&T 734, 734A, and Belden 1505A. For other cable types, check the cable diameter and dielectric OD against the ferrule and center contact dimensions — the 031-70259 is not a universal-fit BNC. The gold-plated center contact (brass base) supports 500 mating cycles, which is above average for a crimp BNC. This makes it a practical choice for field-service test points or equipment that gets reconnected regularly. The nickel body finish resists corrosion in indoor environments. ## Insertion Loss and Signal Performance Rated insertion loss is 0.1 dB — a tight spec that confirms the impedance match and low reflection through the connector. For a 75 Ohm video path, this keeps signal degradation negligible across the cable run. The free-hanging (in-line) mounting style suits patch panels, wall plates, or direct cable termination where a bulkhead jack is not needed.","metaTitle":"Amphenol RF 031-70259 BNC Mini Plug, 75 Ohm","metaDescription":"Amphenol RF 031-70259 BNC mini plug, 75 Ohm impedance, male pin, crimp termination.
