Product details

The 031-70526-21: Rated to 12 GHz, it carries the 75 Ohm characteristic impedance common in video distribution, broadcast, and high-frequency data acquisition — not the 50 Ohm standard of general-purpose RF.

What Ships in the Box

The lockwasher and nut are the front-side mounting hardware for the panel-mount feature — you get everything needed to secure the connector through a panel cutout, no separate hardware order.

Mounting Options and Termination

The nickel-plated brass body provides RF shielding and corrosion resistance. Shield termination is solder — the outer braid of the coax solders to the shell body. The center contact termination is also solder, accepting the signal conductor. The PTFE dielectric maintains consistent impedance through the interface.

Temperature Range and Construction

The center contact material is beryllium copper — chosen for its spring properties and resistance to relaxation over repeated mating cycles — plated with gold for corrosion protection and low contact resistance.

Frequently asked questions

Can 031-70526-21 be used for panel mount?

Yes, the jack supports panel mount with a bulkhead front-side nut. The kit includes the lockwasher and nut needed to secure it through a panel cutout. It also supports board edge end launch mounting for PCB integration.

What is included with 031-70526-21?

The package includes three pieces: the BNC jack connector body, one lockwasher, and one bulkhead nut. The lockwasher and nut are the front-side mounting hardware for panel installation.
