The RW1990 (DS1990 Compatible) 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 RW1990 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 self-aligning with mating receptacles, allowing the DS1990 to be easily operated.
