Product Details

The DS1990R 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 DS1990R 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 DS1990R to be used easily by human operators. Accessories permit the DS1990R iButton to be mounted on almost any object, including containers, pallets, and bags. The DS1990R is a fully compatible variant of the DS1990A. In applications where a presence pulse on contact is critical the DS1990R should be preferred over the DS1990A.
