Bench psu sockets only why!
« on: October 19, 2011, 05:41:23 pm »
Is there a reason other than to cut costs why so many modern bench power supplies only have sockets?
I would much rather have banana posts, so you can clamp a bare wire.

Guess it's partly a matter of personal preference. For me it's rare to use bare wires with binding posts, I usually use banana leads with alligator clips in that case. One issue with binding posts is that they usually don't fit the shrouded banana plugs used with most modern equipment like multimeters. I wouldn't be surprised if costs were the deciding factor, however.

There are 4mm adaptors with cage-clamp

They are safety sockets, to be used with safety plugs, like the one posted above by Richard W.
I see them used mostly  in German equipment, and I believe the reason is to have all cables in the lab with very high insulation (they are rated at 1000 V), with all the plugs protected against an accidental contact (no naked bananas).
I think I've read somewhere that this is the only connector allowed by some safety standard, but now I could not retrieve any information.
It is not an economic reason, they are more expensive than standard binding posts.
The  attached photos show a panel socket and a cable plug.
