Product details

The 031-70534: This is the 75 Ohm variant of the standard BNC interface — not the more common 50 Ohm version — so it matches 75 Ohm video distribution systems, broadcast routers, and HD-SDI signal paths. The kit ships as three pieces: the connector body, the gold-plated brass center contact, and the crimp ferrule.

12 GHz Bandwidth with Bayonet Lock

Rated to 12 GHz, this plug covers the full SDI signal family without a break in the impedance match.

Crimp Termination for Belden 1794A and 4794R

The shield is terminated with a crimp ferrule, and the center contact is also crimped — no solder required. The cable group is specified as Belden 1794A and 4794R, both 75 Ohm precision video coax with solid or cellular polyethylene dielectric. The crimp dimensions are set for these cable diameters; using a different coax will change the impedance match and the mechanical retention.

Frequently asked questions

What is the impedance of Amphenol 031-70534?

It is designed for 75 Ohm video and broadcast systems.

What cable does 031-70534 mate with?

The 031-70534 is specified for Belden 1794A and 4794R precision video coax cables. Using a different cable will affect the impedance match and mechanical fit.

Does 031-70534 include the contact and ferrule?

Yes, the kit includes three pieces: the connector body, one center contact, and one crimp ferrule. No additional parts are needed for termination.
