These come in a variety of sized. 5.5mm OD with a 2.1mm ID (the pin in the middle) is a common size. For DC systems, you also have to know the polarity : center positive means the center pin is positive and the outer shield is grounded or the center pin is grounded and the outer shield is positive. I've always used center positive for DC systems. |
