I'm looking to make a modular system which can be expanded left or right, as well as fed from either left or right side, depending on customer location and available space.
Having a standard outlet in a female connector and input in a male counterpart will make it less flexible since it has a given direction and/or you need to flip the board upside down. One can cheat using two connectors like this simplified example (pardon my MS paint skills):
But is there no magic search term for a connector which has one male and one female part in the same connector to achive the same thing? My google-fu is failing me here.
