High-temperature UHF RFID tag for metal surfaces, 865–868 MHz, Tag-H4-2019

GTIN: 5906935200865 · SKU: Tag-H4-2019

The Tag-H4-2019 is a round, black UHF RFID tag made of metal, designed for metal surfaces in high-temperature conditions. It works in the EU 865–868 MHz and US 902–928 MHz bands, has an Alien Higgs-4 chip and withstands 280°C for 50 minutes and 250°C for 150 minutes. It can be read from up to 140 cm with a handheld reader and up to 270 cm with a fixed reader.

The tag suits the metallurgical industry, where metal components have to be identified and tracked during high-temperature processing. Its heat resistance and durable construction allow components to be tracked in real time, which simplifies asset management and improves the efficiency of the production process.

General instructions​

Before using the RFID tags for the first time, read this manual carefully to make sure they have been installed and configured correctly.

RFID tag usage rules​

The Tag-H4-2019 is a specialised tag — designed to work in harsh conditions, e.g. more resistant to high temperatures, shocks or water. Fasten it to a metal surface through the mounting holes; the tag keeps its reading range on metal, where ordinary RFID tags lose it.

Protection against damage​

  • RFID tags are passive devices and need no power supply. Protect them against mechanical damage to keep them reliable.
  • Use specialised tags as intended and in suitable conditions to ensure they work correctly.

Protection against interference​

  • Electromagnetic interference: RFID tags can be susceptible to electromagnetic interference, so do not store or use them near strong sources of interference, such as electronic devices that generate strong electromagnetic fields.
  • Reading data: to ensure optimal reading, store the tags so that nothing blocks the radio signal — for example, do not store them in metal containers that can interfere with the signal.

Maintenance and cleaning​

Store and operate specialised tags in line with the manufacturer's recommendations for use in harsh conditions.

Storage​

  • If the RFID tags will not be used for a long time, store them in a dry, cool place, away from strong electromagnetic fields.
  • Avoid storing the tags in places with extreme temperatures or humidity, or where they may be mechanically damaged, e.g. crushed.

Following these rules helps keep RFID tags safe to use and increases their durability and reliability.

Frequently asked questions​

Can the Tag-H4-2019 be used directly on metal surfaces?
Yes. The Tag-H4-2019 is specifically engineered for mounting on metal surfaces. Unlike standard RFID tags, which are detuned by metal, this tag maintains full performance when attached directly to metallic objects — making it ideal for tracking metal components, tools and parts in industrial production.
What temperatures can this tag withstand?
The Tag-H4-2019 operates continuously from −40°C to +150°C. For short-duration heat exposure, it survives 280°C for up to 50 minutes and 250°C for up to 150 minutes. Storage is safe up to 200°C. This makes it suitable for processes such as welding, heat treatment, autoclaving and powder coating.
How is the tag mounted?
The tag features two 2 mm mounting holes and measures 20 × 2.1 mm, allowing it to be bolted or riveted directly onto components. This mechanical fastening ensures the tag stays securely attached even under extreme thermal cycling and vibration conditions.
