The bayonet lock mates with any standard mini BNC jack; the 75 Ohm impedance holds only when the cable is RG-179 or a 75 Ohm equivalent with the same dielectric diameter. ## 500-cycle mating duty — field-service reconnect The 500-cycle rating means this plug survives repeated mate/unmate cycles in test equipment, patch panels, or field-service connections where the cable gets disconnected and reconnected regularly. The gold-plated centre contact resists oxidation and fretting corrosion through those cycles. Silver housing colour is cosmetic — the nickel body finish provides the environmental seal.","metaTitle":"TE 1274563-3 Mini BNC Plug, 75 Ohm, RG-179, Obsolete","metaDescription":"TE 1274563-3 mini BNC plug, 75 Ohm, crimp for RG-179, 2 GHz, 500 cycles.
