FAQ:
Q: What size power Jack do I need for my design?
A: If you are choosing a power jack for use in your design, and you are not looking for a specifically unusual one, I would recommend choosing the 5.5 mm O.D., 2.1 mm I.D. size. In my experience it is the most common in hobbyist electronics and related areas.
Q: What is the size of a 5V power plug?
A: Make sure this fits by entering your model number. 『5.5 MM x 2.1 MM Female 5V Socket』: Threaded 5V high current metal dc female receptacle plug; Mount Hole Diameter : 11mm;Total Size : 16 x 17mm/0.63″ x 0.67″ (D*H) 『DC Power Jack 5.5mm x 2.1mm,Durable』: High Quality Metal Copper Material 5.5 2.1 jack, Insulation flame retardant,Fast conduction
Q: Why won’t my Jack make good contact with the Jack?
A: In the 5.5 mm O.D. connectors, if you use the 2.5 mm I.D. plug in the 2.1 mm jack it will not make good contact because the outer housing of the jack may not allow the plug to be displaced far enough for the center to make contact, and in any case the spring will not be exerting the proper amount of pressure since the plug has less thickness.
Q: Does it matter what side the Jack is on the barrel?
A: Yes, it matters. “Barrel” connectors work by having exactly one spring (the outer contact of the jack) which pushes the plug sideways so that the center makes good contact as well as the spring.
