It ships as a 3-piece kit — the connector body, the center contact, and the crimp ferrule — so one line item covers the whole termination. The 75 Ohm impedance marks this as a video-grade BNC, not the 50 Ohm RF standard; use it on SDI, composite video, or broadcast reference runs where the impedance match keeps return loss in check. ## Cable Prep and Crimp Fit Shield and contact are both crimp-terminated. The ferrule crimps over the braid; the center contact crimps onto the center conductor.","metaTitle":"Amphenol RF 031-70257 BNC Plug, 75 Ohm, Belden 1694","metaDescription":"Amphenol RF 031-70257 mini BNC plug, 75 Ohm impedance, crimp termination for Belden 1694/9248 cable.
