Industrial RFID data carriers are rugged RFID tags for manufacturing: LF (125–134 kHz) offers short-range but highly stable reads near metal and liquids; HF (13.56 MHz) delivers medium-range, precise read/write for process tracing; UHF (860–960 MHz) supports long-range (1–10 m+) batch reading at high speed. They are engineered for harsh shop-floor conditions — anti-metal designs, temperature tolerance up to 200°C+, and IP67/IP68 protection — and are widely used in automotive production lines, 3C assembly, tooling/mold management, AGV station positioning, warehouse logistics, and high-temperature processes like painting and heat treatment.
