Screw-terminal barrel plug adapter

$0.60

Description

2.1mmBarrelPlug
This is a 5.5mm/2.1mm standard (Arduino) power plug, with screw terminals. It makes it easy to re-purpose all those spare wall-adapters in your parts box.

Just insert the wires and screw the terminals down. I would also recommend tinning the wires, if you have a soldering iron. Please do check the polarity. The plus terminal goes to the center connector of the barrel which is by far the most common (but NOT UNIVERSAL) setup for power adapters, so please do check the device you are powering to make sure it has the standard polarity (center positive).

Be aware that the plug doesn’t really offer much strain relief. If you think the plug will find its way into an active environment – such as with bands, we’d recommend soldering the wires to the plug, after screwing them in, and or adding a bit of hot glue or epoxy putty for strain relief. Shrink tube could also be useful.
