Flat notched female 2 pin plug for 12V 5A DC power supply
Greetings,
This sort of product would be found under Power, Line Cables and Extension Cords, with a typical process for locating things to be selecting the appropriate Number of Conductors and narrowing down the remaining options based on the 2nd Conductor.
Unfortunately I didn’t find anything that appears to match; it’s not terribly uncommon to find overmolded plugs of this sort that don’t appear to follow the more common standards. We do have a fair number of supplies rated for 12V/5+A however, which may offer an option if one can’t find a suitable AC-side cord somewhere.
