Product details

The 031-70526-23: This particular variant is built for 75 Ohm systems — the impedance that distinguishes it from the more common 50 Ohm BNC — making it the correct choice for video, CCTV, and broadcast signal paths where 75 Ohm is the standard. Rated to 12 GHz, this jack handles high-frequency video and data signals well beyond the typical baseband video range. The nickel-plated brass body provides the standard BNC shielding and environmental durability.

Mounting and Termination Detail

This jack supports two mounting styles: board-edge end launch, where the connector sits at the edge of the PCB and the signal pin is soldered directly to a trace, and panel mount, where the bulkhead nut clamps the connector to a chassis or enclosure panel. The shield termination is solder-type, meaning the outer braid of the coaxial cable is soldered to the body for a continuous ground path. The contact termination is also solder, requiring the center conductor to be soldered to the beryllium copper pin.

Frequently asked questions

Where can I buy 031-70526-23?

The 031-70526-23 is available to order through independent distribution. It is sourced and quoted against an RFQ; current pricing and lead time are confirmed at the time of your quote request.

What is the difference between 031-70526-23 and 031-70526-22?

Both share the same BNC form factor and bayonet lock, but the impedance difference means they are not electrically interchangeable — the 75 Ohm version is for video/broadcast, the 50 Ohm for RF/data.
