These are great little connectors—just solder power wires on the back of each and mount the connectors in a housing, and you've got an instant, plugless power transmission system.
People have asked if there is any set polarity to these—the answer is no, as long as you use the same configuration for all connectors while soldering (i.e., center positive, shell negative). When we solder these up, we go with center positive, but at the end of the day, these are just pass-through connectors, meaning the shell always mates with the shell and the inner pin always mates with the inner pin.
The "clutch power" on the magnets is quite strong. In our tests using LEGO® train cars with the magnets as couplers, one pair was able to pull multiple coaches.
This is a DIY (Do-It-Yourself) product, and requires soldering to use.
