Description: This DC power jack/connector is just like the other one that we carry except that it’s terminated with breadboard-friendly pins instead of wide solder terminals. These are also compatible with our DC wall supplies and have a 5.5mm jack, with a 2.1mm center pole diameter.

It is worth mentioning that there is one positive and two negative poles while there is no plug plugged in. However, when the plug is plugged in there is only one negative and one positive pole (the one on the side is not used). Otherwise it is a very good product.

I used one of these many times to easily power a breadboard. The only thing lacking here is the confusing circuit diagram in the datasheet. Otherwise, the product is great and fits perfectly in normal spacing breadboards.
I highly recommend these if you are building PCBs. Well made, the small mounting pins easily mount to the PCB as advertised. Very sturdy once soldered.
