Unique ID / item-level identification and data encoding

As Xerafy’s leading rugged RFID tags, the MICRO series comes with 6 references that have been proven in the field around the world, and work in combination with the PICO small tags and XS smallest RFID tags.

The tags’ RFID chip is protected from high temperatures, shocks, abrasions, pressure, water, and corrosives like acids, by using patented combinations of packaging and engineered casing materials.

Metal inserts enhance the durability of the tags, especially when utilized with robust mounting systems such as rivets and screws.

What are the MICRO series RFID tags used for?

The MICRO series RFID tags are used in manufacturing paint shops, automotive work-in-process, production lines, as well as aerospace, oil and gas, and healthcare.

Their technical features make them the ideal durable tagging solution to track assets in challenging industries.

Can the MICRO series RFID tags perform on metal surfaces?

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.

What are the maximum temperatures for MICRO series RFID tags?

The MICRO series RFID tags can survive maximum temperatures of up to 250°C. The tags have also been tested in various high-temperature cycles that are typical of industrial processes such as paint shops.

The Xerafy engineering team can advise on the best tag selection for specific cycles and assist with testing.

Can the MICRO series RFID tags withstand acid and alkali?

Yes, their materials offer protection to varying types and concentrations of acid or alkali typical of industrial environments. Some acid or alkali may corrode or damage the tag over time, while others may have little to no effect.

The Xerafy engineering team can advise on the tagging solutions best suited to the environmental conditions in which the tags will be used and assist with testing.

Are MICRO series RFID tags waterproof?

Yes, each of the MICRO series tags is waterproof and comes with its own IP rating. The tags are designed to be resistant to water and moisture, making them suitable for use in outdoor or wet environments.

MICRO-waterproof-186x140 MICRO | high temp

An IP rating, for Ingress Protection, sees the first number referring to protection against solids, and the second number referring to protection against water. The most common IP ratings for industrial RFID tags are:

  • IP54 – Against contamination from limited amounts of dust and other particles, and water sprays from all directions.
  • IP68 – Against immersion.
  • IP69k – Dustproof and can withstand pressurized washdown at high temperatures.

How reliable are the MICRO series RFID tags?

The MICRO series are benchmark-topping rugged and reusable RFID tags. They have been validated in the field by industry leaders for challenging environments, including high temperatures, exposure to chemicals, pressure, and waterproof conditions.

The Xerafy engineering team is available to support the selection and qualification of a tagging solution best suited to the environmental conditions in which the tags will be used.

What RFID readers work with the MICRO series?

MICRO series tags work with standard RFID readers from Zebra, Honeywell, TSL, etc that comply with EPCglobal Gen2v2 and ISO 18000-63 standards, also referred to as RAIN RFID.

Advice is available on a selection of fixed and handheld RFID readers with frequencies and antenna polarization matching the tags’ for optimal performance.

How to securely attach the MICRO series RFID tags on metal assets?

The MICRO series can be mounted on metal assets using pop rivets, screws, cable ties, as well as industrial adhesives and glues.

The Xerafy engineering team can advise on the mounting solutions best suited to the assets and environmental conditions in which the tags will be used.
