DS1990R-F3 2.80 €
Serial Number iButton
The DS1990R-F3 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-F3 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-F3 to be used easily by human operators.

Accessories permit the DS1990R-F3 iButton to be mounted on almost any object, including containers, pallets, and bags. The DS1990R-F3 is a fully compatible variant of the DS1990A. In applications where a presence pulse on contact is critical the DS1990R-F3 should be preferred over the DS1990A.
