Product details

75 Ohm BNC Bulkhead Jack for Broadcast Video

The 031-70568-12G: It's built for the 75 Ohm video/broadcast world — not the 50 Ohm RF bench. Rated to 12 GHz maximum frequency, it covers the full HD-SDI bandwidth and then some. This is a crimp-termination connector: the centre contact crimps, and the shield terminates via a crimp ferrule. The kit includes six pieces: one connector body, one centre contact, one ferrule, one insulator, one lockwasher, and one nut — everything needed for a single bulkhead install except the cable and crimp tool.

500 Mating Cycles, Gold Centre Contact

The nickel-plated brass body provides RF shielding and corrosion resistance. The bulkhead front-side nut secures it to the panel; the lockwasher prevents loosening under vibration.

Frequently asked questions

Where can I buy 031-70568-12G and how is it quoted?

Submit an RFQ for your volume and delivery window.

Is 031-70568-12G a 75 ohm or 50 ohm BNC connector?

It is not the 50 Ohm version — the impedance is a fixed selection parameter. Use it with 75 Ohm cable such as Belden 1794A or 4794R.

What cable works with 031-70568-12G?

The connector is specified for Belden 1794A and 4794R cable groups. The crimp ferrule and centre contact are sized for these cables; using a different cable requires verifying the dielectric diameter and centre conductor size against the crimp tooling.

What accessories are included with 031-70568-12G?

The kit includes six pieces: one connector body, one centre contact, one ferrule, one insulator, one lockwasher, and one nut. That covers the full bulkhead install — you supply the cable and crimp tool.
