Anyone have any suggestions for a suitable connector pair?Ĭlick to expand.That was one of the options I had been thinking about. So I have had some trouble finding anything I really liked. I think these are usable, but the plug is awkwardly long.


Surely there is a less expensive alternative? I did find these ( ), but nearly $14 Canadian per connector is a bit much. Oh yeah, if at all possible, it should be available at Digikey or Mouser.īasically, I'm looking for a 3-pin replacement for the everyday 5.5mm "barrel jack" and "barrel plug" connectors we find on most of our contemporary small power supplies and the products they plug into.

To power these, I would like to find a suitable power connector that has (at least) three pins, is reasonably small and compact, can carry a reasonable amount of current - say 100 mA DC minimum - and which electrically isolates all three pins from whatever metal box the connector is mounted to. I'd like to build these into little die-cast boxes of the sort used for guitar FX pedals. I am planning some op-amp based projects that need both positive and negative supply rails, the usual 0V, +15V, -15V.
