The connector is rated to 12 GHz, which puts it well beyond standard SDI rates (3 GHz) and into the 12G-SDI range, meaning it handles UHD/4K video links without signal droop at the connector interface. ## Kit Contents — Connector, Contact, Ferrule The contact and ferrule are specific to Canare L-3.3CUHD — the ferrule inner diameter matches the cable jacket OD, and the contact barrel is sized for the center conductor. If you are terminating a different cable, the crimp dimensions will not seat correctly. The kit format simplifies field termination: one order code gets you everything except the cable and the crimp die. ## Bayonet Lock, Free-Hanging Mount, 500 Cycles Fastening is standard BNC bayonet lock — quarter-turn mate, positive detent. The connector is free-hanging (in-line), not panel-mount, so it terminates the cable end and mates with a bulkhead jack or another in-line adapter. The brass body with nickel finish gives reasonable corrosion resistance for indoor broadcast racks and field camera cable assemblies. Operating temperature range is -30°C to 85°C, covering outdoor broadcast vans and unheated equipment rooms. ## Termination: Crimp Shield, Crimp Center The shield termination is a crimp ferrule that compresses over the braid; the center contact crimps onto the center conductor. For Canare L-3.3CUHD, the recommended crimp die for the hex crimp tool is typically a 0.178-inch hex for the center pin and a 0.255-inch hex for the ferrule (verify with your tool manufacturer's die chart).","metaTitle":"Amphenol 031-70555-12G BNC Jack, 75 Ohm, 12 GHz","metaDescription":"Amphenol RF 031-70555-12G BNC jack, 75 Ohm, 12 GHz, for Canare L-3.3CUHD cable.
