The kit includes the connector body, one gold-plated brass center contact, and one ferrule, all in a single bulk package. ## Cable Groups and Termination Fit The ferrule and contact are sized for RG-141 and Belden 89907 / 9907 cable groups — the same 0.195-inch diameter class. The crimp tooling for the center contact and the hex die for the ferrule follow standard BNC crimp profiles; no special adapter needed. The shield termination is crimp, not clamp or solder, so the braid gets a gas-tight connection that holds up to vibration. There is no official successor listed. If the application can tolerate a parametric alternative, a standard 50 Ohm BNC plug from the same or equivalent series (e.g., a TE 5221128-x variant or a generic Amphenol BNC) may fit, but that cross-reference must be verified against the cable group and center contact dimensions. ## 500 Mating Cycles — Field-Service Duty The nickel body finish also holds up to repeated handling and field reconnection — this is not a one-crimp-and-forget connector.","metaTitle":"TE BNC Plug 2-5221128-7, 50 Ohm, 4 GHz, Obsolete","metaDescription":"TE BNC plug, male pin, 50 Ohm, 4 GHz max, 500 V, crimp termination.
