Industrial UHF RFID tag, 865–868 MHz, for metal surfaces and concrete, Tag-U8-4601

GTIN: 5906935200896 · SKU: Tag-U8-4601

The Tag-U8-4601 is a black, industrial UHF RFID tag in a durable PPS housing, designed for the construction industry. It is mounted on metal surfaces with two screw holes or embedded in concrete, so it suits tracking building materials and assets on construction sites. It works in the EU 865–868 MHz and US 902–928 MHz bands, has an Alien Higgs-3 chip and can be read from up to 6.6 m on metal with a fixed reader and up to 1.9 m when embedded in concrete at a depth of 5 cm.

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-U8-4601 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 two mounting holes or embed it in concrete; 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-U8-4601 be embedded in concrete?
Yes. The tag is specifically designed for embedding in concrete at depths up to 5 cm. At this depth, the reading range is up to 1.9 metres using a stationary UHF RFID reader. The PPS material and IP68 rating ensure the tag withstands the alkaline environment inside concrete over its entire service life.
Is the tag compatible with standard UHF RFID readers?
Yes. The Tag-U8-4601 operates in the standard UHF RFID band (865–868 MHz for Europe, 902–928 MHz for the US) and is compatible with any reader conforming to EPC Gen 2 / ISO 18000-63 standards. It can be read by both handheld and fixed UHF RFID readers.
How is the tag attached to metal surfaces?
The tag features two 3.6 mm mounting holes for mechanical fastening with screws or bolts directly to steel, aluminium or other metal surfaces. Its design ensures stable signal performance even when mounted on metal, unlike standard RFID tags which lose range on metal substrates.
