These are small rare earth magnets - 3/16" rings. Composed of Neodymium/Iron/Boron (NdFeB), these magnets are curiously strong and make for a great way to attach tools to a metal workbench, hold small children to a fridge, and as a trigger for reed switches. This one small ring can easily hold a piece of paper to your fridge.

We found these small rings to be very useful for connecting PCBs together. These rings are conductive and can act as a magnetic connector between widgets. You need a way to secure the ring to the PCB (screws and rivets have been shown to work).

Sold in single units.

這些都是小稀土磁鐵 - 3/16“環組成釹/鐵/硼(釹鐵硼),這些磁鐵是好奇地做強,做大的附加工具,金屬工作台一個偉大的方式,舉辦小型的孩子一台冰箱,並以此為簧片觸發開關,這一個小小的環能輕鬆容納一張紙給你的冰箱。

我們發現這些小環是連接在一起的PCB非常有用。這些環是導電的,並且可以作為小部件之間的磁性連接器起作用。需要一種方法來將環固定到PCB(螺絲和鉚釘已被證明工作)。
