The DS1990R iButton® is a rugged serial number identifier that serves as an electronic registration number for automatic identification. Data is serially transferred via the 1-Wire® protocol, which requires a single data cable and ground return. Each DS1990R is manufactured by laser process and contains a unique, guaranteed 64-bit registration number that allows absolute traceability.
The rugged stainless steel iButton enclosure is highly resistant to environmental factors such as dirt, moisture and shock. Its compact button-shaped profile is self-aligning with the coupling housings, allowing the DS1990R to be easily used by operators.
Accessories allow the DS1990R iButton button to be mounted on almost any object, including containers, pallets and bags.
