The DS1990A is factory lasered with guaranteed unique 64bit 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 DS1990A to be used easily by human operators. Accessories enable DS1990A iButton to be mounted on almost any object including containers, pallets and bags. This can be easily affixed with self stick adhesive backing latched by its flange or locked with ring pressed onto its rim.
