The Type of ear Tag


Product Overview
This 30mm electronic ear tag features an embedded EM4305 chip operating at 134.2kHz frequency, compatible with both ISO 11784 and ISO 11785 protocols. The TPU material offers eco-friendly properties, and the compact overall structure does not interfere with normal livestock behavior after application. The chip supports repeated read/write operations and, when used with handheld HDX reading devices, enables rapid identification and data retrieval of 15-digit unique codes.
This product is suitable for various livestock including pigs, cattle, sheep, goats, deer, and camels, with proven applications in livestock farming, pet registration, and laboratory animal management.
HDX vs FDX Technology Comparison
The core difference between these two technology approaches lies in the data transmission mechanism: FDX (Full Duplex) solutions offer lower cost, while HDX (Half Duplex) solutions deliver superior performance in signal stability and reading distance.
Typical Application Scenarios
Farming enterprises use this system to establish individual records covering data dimensions such as growth curves, feeding cycles, and breeding pedigrees. Veterinary personnel can instantly access historical medical records during clinical treatment or disease investigation. Livestock regulatory authorities utilize it for inventory statistics, epidemic source tracing, and food safety supervision. After pet registration and connection to global databases, lost pets can be reunited with their owners by scanning the chip.
Installation Guidelines
Use the matching ear tag applicator to pierce and secure the male and female tags at an appropriate position on the ear. During operation, avoid areas with dense blood vessels. The piercing depth should allow the tag to sit flush against the ear surface; excessive depth may cause infection. Immediately after application, verify chip response with a reader and confirm the code is correct before releasing the animal.
