Glass tube electronic tags primarily operate at low frequencies of 134.2kHz or 125kHz, with ultra-high frequency (UHF) products also available. Common chip types include EM4305, TK4100, and HITAG-S256. Package sizes range from 1.25mm to 4mm in diameter and 7mm to 34mm in length, such as ф1.25*7mm, 1.4mm*8mm, 2.12*12mm, and 3.85*32.2mm. Operating temperatures are typically -20℃ to +50℃ or -25℃ to +85℃, while storage temperatures can reach -40℃ to +70℃ or -20℃ to +80℃.
Reading distances are generally 2-10cm for low-frequency products (depending on the reader), while newer UHF products offer significantly increased reading distances. Storage capacities can reach 1024 bits, 1360 bits, or 2Kbits. The lifespan is typically greater than 10 years, with some products rated at over 20 years. In terms of read/write cycles, read/write mode products can reach 100,000 or even over 1 million cycles. The encapsulation material is bio-glass (such as borosilicate glass), often coated with a parylene C bio-coating to prevent slippage and corrosion. The power supply is passive (passively activated). Standards comply with ISO11784/85 international standards (primarily FDX-B protocol, but HDX protocol products are also available).
