Are there any HF tags that will continue to operate after being exposed to a temperature of 250 degrees Fahrenheit (121 degrees Celsius) for a maximum of 3.5 hours?
Yes, but you would likely need to conduct testing in order to make sure that the tags you choose will work for your particular application.
RFID Infotek manufactures a laundry tag known as RFIT Harsh Enviorement Tag Pro, which the company says will function at temperatures as high as 110 degrees Celsius (230 degrees Fahrenheit). The tag can be stored at 180 degrees Celsius (356 degrees Fahrenheit) for 80 hours, and will continue to operate if the temperature lowers to 110 degrees Celsius or below.
Avante offers custom tags that can withstand long-term temperatures as high as 150 degrees Celsius (302 degrees Fahrenheit), and short-term temperatures as high as 300 degrees Celsius (572 degrees Fahrenheit).
There's also William Frick & Co.'s HTL1 high-temperature RFID label, which the firm claims will survive temperatures up to 180 degrees Celsius for 30 minutes or more. You would need to test if it could survive 250 degrees Fahrenheit for 3.5 hours.
In addition, you could simply search the Web for "laundry RFID tags." You might find other high-temperature tags that would meet your needs, though many only withstand temperatures ranging from 50 degrees Celsius to 80 degrees Celsius (122 degrees Fahrenheit to 176 degrees Fahrenheit).
