Product details

The 031-70235: It is built for video, broadcast, and CCTV signal paths where the 75 Ohm characteristic impedance matches the cable and equipment.

The 500 mating cycles, paired with gold-on-brass centre contact plating, mean this plug survives repeated reconnections in patch bays, field test kits, and production racks without the centre pin wearing through to base metal.

Crimp Termination and Bayonet Lock — Field-Ready Build

Free-hanging in-line mount with a bayonet lock — the twist-to-mate coupling gives a positive mechanical latch without tools. Shield termination is crimp, using the supplied ferrule over the braid; the centre contact is also crimp. The PTFE dielectric handles the -40°C to 155°C operating range, which covers outdoor enclosures and near-engine compartments without dielectric breakdown.

Frequently asked questions

What cable does the 031-70235 work with?

It terminates RG-59, Belden 1426A, 1501A, 8281, and 9100 coax cables. The crimp ferrule and centre contact are sized for these cable groups.
