Product details

Mini BNC Jack for RG-179 — 75 Ohm, Panel Mount, Crimp Termination

The 1274568-3: It comes as a kit with the connector body, one center contact, and one ferrule — everything needed for one cable termination. The 75 Ohm impedance and 2 GHz frequency ceiling make it a fit for video distribution, CCTV, and broadcast equipment where standard BNC is too large for the panel density.

What Bolts In — Panel Fit and Cable Prep

The gold-plated phosphor bronze center contact handles 500 mating cycles without fretting.
