Product details

75-Ohm BNC Plug for Belden 4694R — What It Is and What It Does

The Amphenol RF 031-70548-12G is a 75-Ohm BNC plug designed specifically for Belden 4694R precision video coax. 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.

Frequently asked questions

Is 031-70548-12G compatible with Belden 4694R cable?

Yes, the 031-70548-12G is specifically designed for Belden 4694R cable. The cable group is listed in the spec, and the kit includes the ferrule and gasket that match that cable's braid diameter.
