It ships as a three-piece kit: the connector body, a crimp contact, and a ferrule, so you get everything needed for one termination in a single order code. Rated to 2 GHz with 0.15 dB insertion loss and a 500 V voltage rating, this plug handles baseband video, CCTV, and legacy broadcast distribution runs without breaking a sweat. ## Obsolete — Sourced on the Surplus Channel The 5221185-2 is officially obsolete per the manufacturer's lifecycle record. No direct-replacement order code from TE Connectivity is listed. If you are designing a new harness, look at current-production 75 Ohm BNC plugs from the same family; the 5221185 base number is the legacy reference. ## Termination Checklist — Crimp Both Ends The centre contact is brass with gold plating, crimped to the RG-59 centre conductor. The shield termination is a separate crimp over the ferrule — the zinc die-cast body gets its nickel finish from that ferrule-and-shell assembly. No solder, no clamp: strip the cable to the dimensions in the TE application drawing, crimp the contact, then crimp the ferrule over the braid. ## Bayonet Lock and Free-Hanging Mount Free-hanging (in-line) mounting with a bayonet lock — no panel cut-out, no jack-screws. The plug mates to any standard BNC jack with the matching 75 Ohm interface. The bayonet slots engage with a quarter turn and the lock ring seats positively; the 500-cycle rating means the plating on the lock ramp holds up through repeated mate-unmate cycles in field-service or test-equipment use.","metaTitle":"TE Connectivity 5221185-2 BNC Plug, 75 Ohm, 2 GHz, Obsolete","metaDescription":"TE Connectivity 5221185-2 BNC plug, 75 Ohm, 2 GHz, 500 V.
