This (the original) is the typical "tricky" question where someone has the completely wrong piece of equipment. Mouser is an authorized distributor for many AC Adapter manufacturers including Cincon, CUI Inc., Inventus Power, MEAN WELL, Phihong, SL Power, TDK-Lambda, XP Power & more. ![]() Mind you, honestly, which gender does the line fitting actually resemble when you think about it?
