Choosing RFID Transponders and Tags components

RFID tag selection is driven by frequency band (each has different range and material-tolerance characteristics), memory capacity, and the matching reader/antenna ecosystem. Tags from one frequency family will not be read by readers of another — and even within the same frequency, vendor-specific extensions can require matched ecosystems.

Specs to confirm before ordering:

  • Frequency: LF (125/134 kHz) — short range (~10–100 mm), metal-tolerant; HF (13.56 MHz) — medium range (~100–500 mm), good general purpose; UHF (860–960 MHz) — long range (1–10 m), but reduced near metal/liquid
  • Protocol: ISO 11784/85 (LF), ISO 14443 (HF, like NFC), ISO 15693 (HF, longer-range NFC variant), ISO 18000-6C / EPC Gen2 (UHF)
  • Memory capacity: read-only ID (factory-programmed), user-writable EEPROM (typical 752 bytes to 64 kB), or extended FRAM memory
  • Form factor: button disc, screw, plug-in plate, label, embedded mount
  • Operating temperature — industrial tags rated to 85 °C, high-temp variants to 200+ °C for autoclave or heated environments
  • Mounting: direct on metal (specific metal-mount tags only), embedded in plastic, surface adhesive
  • IP rating
  • Read/write cycle life — EEPROM-based tags typically 100,000+ write cycles; FRAM tags effectively unlimited

Common gotchas: standard HF and UHF tags mounted directly on metal lose 80–95% of their read range — use metal-mount tags (with absorber backing or specific antenna design) for metal applications. UHF tags have polarization (linear vs. circular antennas); a circular-polarized reader works with any tag orientation while linear requires alignment. Tag memory layout (where ID is stored vs. user data) varies by manufacturer — copying data from one tag generation to a newer one may need a memory-map remap.

Typical applications: tool ID on CNC machines for setup recall, part traceability on automotive assembly lines, machine setup parameter storage on changeover modules, asset tracking in warehouses (UHF), pallet-level tracking for shipping, and product-flow tracking in production.

Frequently asked questions
Do you stock obsolete RFID tags and transponders?
Yes. Discontinued Balluff BIS-C codes, retired Pepperl+Fuchs IPT first generations, end-of-life Siemens SIMATIC RF200, and earlier Turck BL ident are sourced through our supplier network.
Will my tag work with a different reader?
Same frequency and protocol (e.g., both ISO 15693): yes for read. Read/write of user memory may require the vendor-specific memory map. Different frequencies are not interchangeable — LF tags do not work with HF readers, and vice versa.
Why do my UHF tags not read on metal?
UHF antennas detune when placed directly on metal. Use metal-mount tags (with built-in absorber and antenna geometry designed for metal mounting) or mount standard tags on a spacer (typical 6+ mm of plastic or foam between tag and metal).
Can I overwrite the tag ID?
For tags with user-writable memory, yes — user memory is rewritable. The fixed ID/EPC is typically locked at manufacture. Some tags allow ID rewrite within specific specs; check the OEM datasheet.
How long do RFID tags last?
EEPROM-based tags: 100,000+ write cycles and 10+ year data retention. FRAM-based tags: effectively unlimited write cycles. Physical lifespan depends on environment — high-temperature, chemical, and impact exposure shorten life.
What is the warranty?
12-month functional warranty on the tag. Damage from physical impact, exposure beyond rated temperature, or chemical attack is not covered.
