Introduction:
The TM1990A 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 TM1990A 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 selfaligning with mating receptacles, allowing the TM1990A to be used easily by human operators.
Accessories enable the TM1990A iButton to be mounted on almost any object, including containers, pallets, and bags.
