The Can and Grommet - ibutton

An iButton uses its stainless steel 'can' as an electronic communications interface. Each can has a data contact, called the 'lid', and a ground contact, called the 'base'. Each of these contacts is connected to the silicon chip inside. The lid is the top of the can; the base forms the sides and the bottom of the can and includes a flange to simplify attaching the button to just about anything. The two contacts are separated by a polypropylene grommet. The silicon chip within the iButton is protected by the ultimate durable material: stainless steel. We can drop an iButton, step on it, or scratch it. The iButton is wear-tested for 10-year durability.
