General Description
The DS1990A serial number iButton® is a rugged data carrier that serves as an electronic registration number for automatic identification.
Data is transferred serially through the 1-Wire® protocol, which requires only a single data lead and a ground return.
Every DS1990A is factory lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability.
The durable stainless-steel iButton package is highly resistant to environmental hazards such as dirt, moisture, and shock.
Its compact coin-shaped profile is selfaligning with mating receptacles, allowing the DS1990A to be used easily by human operators.
