If you love power adapters or toys & gadgets that have magnetic connections, you can now experiment with these futuristic connectors easily. It's sorta like a DIY "MagSafe-styled" connector, with seven 2.2mm spaced contact pogo pins and a straight solderable connection to your PCB. If you've ever owned a MacBook or a littleBits set, you'll find the functionality familiar. This pitch is too small for standard breadboarding, but we carry 2.54mm magnetic connectors over here.
