The kit ships as three pieces: the connector body, the ferrule, and the gasket, so you don't have to source those separately. 75-Ohm impedance, 12 GHz max frequency. Gold-plated brass center contact, nickel-plated phosphor bronze body, 500 mating cycles. ## Cable Compatibility and Field Fit This plug is dimensioned for Belden 4694R — the cable group is stamped right on the spec. If you're terminating Belden 4694P instead, the sibling 031-70558-12G uses the same body but swaps the gasket for a separate contact. For RG59 or other 75-Ohm cables, the dielectric diameter and braid OD won't match the ferrule and center contact bore; you'd need a different Amphenol BNC kit for those cables. The PTFE dielectric keeps phase stable across that span.","metaTitle":"Amphenol RF 031-70548-12G BNC Plug, 75 Ohm, Belden 4694R","metaDescription":"Amphenol RF 031-70548-12G BNC plug, 75 Ohm, for Belden 4694R cable.
