70 mm Long range Anti Metal Circular Industrial HF RFID Tag High Frequency RFID Transponder

Physical Dimensions: 50mm in diameter. Larger dimensions typically mean a more powerful antenna, resulting in superior performance.

Key Technology: Designed specifically for metal resistance. The tag's back integrates special materials (such as a ferrite absorbing layer or a thermal insulation layer of a specific thickness) to effectively counteract interference and energy absorption from metal surfaces, ensuring stable operation on metal surfaces.

Environmental Protection: IP67 rating. Completely dustproof and can withstand brief immersion (1 meter underwater for 30 minutes). Suitable for extreme environments such as outdoor use, washing, high humidity, and oil contamination.

Operating Frequency: High Frequency (HF, 13.56MHz). In metal-resistant environments, HF tags offer significant advantages over UHF tags, providing a stable reading area and immunity to interference from surrounding metal objects, making them suitable for accurate and reliable short-range identification in complex metallic environments.
