The connector is rated to 12 GHz maximum frequency, supporting high-bandwidth video signals such as 4K/8K uncompressed video or satellite IF distribution. The kit includes three pieces: the jack body, a crimp contact, and a cable ferrule — one order code covers the full termination hardware. This jack is pre-engineered for Belden 4694P, a precision 75 Ohm coaxial cable commonly used in broadcast video and HD-SDI installations. The shield termination is crimp, and the center contact is also crimp — a standard field-termination method that gives a reliable, repeatable connection without soldering.","metaTitle":"Amphenol 031-70557-12G BNC Jack, 75 Ohm, 12 GHz","metaDescription":"75 Ohm BNC jack, 12 GHz max, for Belden 4694P cable.
