Non-Magnetic AUTHENTIC Dallas Key
Please be aware of Asian Counterfeits - they do not have Unique ID's and compromise "Security of Use". The Unique ID is the fundamental principle for selecting iButton®. Unless the part number has a "DS" in front of the 1990 and a iButton® Registration Symbol - it's a Counterfeit.
The technology used in Counterfeit Keys is also easily copied negating the whole principle of designing with iButton® and its Unique ID Security feature.
