The MICRO series high-temperature RFID tags provide advanced identification and on-metal tracking capabilities to assets in demanding operations:
The Xerafy MICRO series is made of RFID tags for manufacturing (paint shops, work-in-process, production lines…), as well as aerospace, oil and gas, and healthcare.
Their technical features make them the ideal rugged tagging solution to track assets in challenging industries.
Yes, they are specifically designed to perform on metal surfaces.
Ordinary RFID tags cannot be used for metal assets: The metal interferes with RFID signals, causing problems with readability and accuracy. The Xerafy MICRO series, on the other hand, are industrial RFID tags that use antennas designed to work on metal surfaces without interference, as well as techniques such as orientation optimization.
MICRO Paint Shop is rated for high-temperature exposure at 250°C for 500 hours. MICRO Heat has a survival rating of 215°C for 48 hours. Both models support RFID reading and writing from −40°C to +85°C.
For repeated production cycles, the exposure rating alone does not establish service life. Temperature, time per cycle, chemical exposure and mounting all matter.
Share your process requirements with Xerafy Engineering to select the right tag and mounting method for your production line.
Operating temperature is the specified range for reading and writing RFID data.
Survival temperature describes the heat exposure a tag can withstand under stated conditions, including exposure duration. It does not establish read/write performance at that temperature.
To qualify a tag for your process, share the peak temperature, exposure time, number of cycles, steam or chemical exposure, mounting method and planned read points with Xerafy Engineering.
Yes, Xerafy RFID tags can be used in medical autoclaves or sterilization processes.
The MICRO Medical, MICRO Autoclavable and ROSWELL Autoclavable are specifically engineered for the healthcare industry, capable of withstanding rigorous cleaning and sterilization procedures without losing functionality.
These tags ensure reliable performance through repeated reprocessing cycles, making them ideal for tracking surgical instruments and equipment in sterile environments. This durability supports effective asset management and compliance with health safety standards.
