Equipped with the industry's top IMPINJ E710 chip

U20’s receiving sensitivity is up to 4dB. There are 3 frequency bands of 920-925 MHz, 902-928 MHz, and 865-868 MHz. It supports for EPC C1 GEN2/ISO18000-6C protocol , and has stable performance of label recognition in a variety of scenarios.

U20 UHF RFID Mobile Computer

The group reading speed of RFID label is up to 200 tags per second

U20 enables fast and efficient RFID tag scanning and data collection. It enhances inventory management, saves time, provides real-time tracking capabilities, ensures data accuracy, and offers scalability for various applications.

4dBi circular polarization antenna

U20 supports wide-range scanning, and scanning distance is up to 12M. There are nearly no any requirements on the direction of tags, so that scanning and reading applications are more flexible, more accurate, and more convenient with high efficiency during daily work.

IP65, waterproof and dustproof

With IP65, U20 offers high performance and protection in terms of dust and water resistance. It can operate in harsh environmental conditions such as dusty environments or withstand short-duration water exposure.
