VS1990A 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 VS1990A guaranteed unique 64-bit registration number that allows for absolute trace ability. 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 VS1990A to be used easily for guard patrol.
