Gold Plated BNC Hardware
 
Does anyone know of a source of gold plated 75R BNC Plugs and sockets please. Some plugs are sold by Supra but they look like 50R. I am mainly interested in sockets. Manufacturers have them but no one else seems to sell 'em. :cool:

Would you settle for Rhodium plated brass? http://www.cardas.com

I know about Cardas, thanks. But I am looking for the gold ones that Wadia, Linn and others use.

What about http://www.partsconnexion.com/catalo.../sheet006.html

They have gold plated BNCs, although there is no mention of the impedance. I think these are for audio applications, so hopefully they are 75 ohms.

Hope this helps,
Stu

Most BNCs have gold-plated center pin.

The vast majority of BNCs are 50 Ohm characteristic impedance.
Very few BNCs are 75 Ohm and the design of these makes them
less rugged. (it's very common to have 50 Ohm BNCs that
mate to 75 Ohm coaxes)

I doubt that for even digital audio interconnections the
difference in connection impedance will be noticable in
either objective or "subjective" terms.

What makes (what it depends on) the impedance of BNC connector to be either 50 or 75 ohms?

Centre pin to outer jacket diameter ratio and dielectric.

Not listed under url or in catalog; where did you pick this up from pl?;)

Go to the bottom of the frame and click the link that says "BNC Connectors." That was as close as I could get using the link. Sorry.

There are no pictures, but they say cable mount, so probably not want you want anyway.

Have you tried CPC?

Check here...

Doesn't specify impedance, but they mention RG58 cable, which is 50ohm. I bought some of these a while back, and the quality is pretty good for the price...

Hope this helps,

Mark
