BNC Connectors Zinc VS Copper

Recommended Posts

Does it really make a differnce zinc vs copper? i hooked up two same exact cameras, both on 1000ft spools and see no difference.

 

Would the only differnce be the life of the connector?

I cant see why it would make any positive difference at all, that would be viewable to the human eye.

 

If anything, using a connector made from a different metal than the mating socket may actually introduce the risk of disimilar metal corrosion (speculating here, as its not a area I am expert in...)

According to the above charts, zinc seems to react with a lot of metals, if a reaction did occur it could cause a negative effect over time on the picture, and the life of the connectors...

 

No idea if it would happen though, but I have seen warnings in motherboard manuals from time to time warning against adding gold plated sims to tin plated sockets and vice versa due to this problem.
