The 031-10-75RFXG2: The 75 Ohm impedance targets video distribution, CCTV, broadcast, and telecom baseband signal paths — not the 50 Ohm test-and-measurement world. It carries a 4 GHz frequency ceiling with 0.2 dB insertion loss, which covers HD-SDI and composite video without pushing into microwave territory.
Panel Mounting and Included Hardware
Mounting type is panel mount with a bulkhead rear-side nut feature — the connector passes through the panel from the front and the nut tightens from behind. The isolated feature means the connector body is electrically isolated from the panel ground, which is typical for video applications where ground loops need breaking.
75 Ohm vs 50 Ohm Sibling — 031-10-RFXG1
The closest cross-shop candidate is the 031-10-RFXG1, which shares every spec except impedance: 50 Ohm vs 75 Ohm. Same brass body, nickel finish, gold centre contact, 500 mating cycles, 4 GHz bandwidth, 0.2 dB insertion loss, and the same included lockwasher and nut. The impedance difference is the only selection axis — 75 Ohm for video/telecom, 50 Ohm for RF test and instrumentation. No other functional delta exists between the two.
