Ⅰ Product introduction

  The ZJ6022-3DBI is a high-performance UHF band reader-writer for electronic tags compliant with the ISO18000-6C (EPC C1G2) protocol. It is designed with independent intellectual property rights. By combining a proprietary and efficient electronic tag collision handling algorithm, it can achieve fast reading and writing processing of electronic tags while maintaining a high reading rate. It can be widely applied to various wireless radio frequency identification (RFID) systems, such as logistics, personal identification, intelligent parking lots, access control systems, anti-counterfeiting systems, and production process control.

1. Designed with independent intellectual property rights.
2. Fully support electronic tags compliant with the UHF EPC Gen2 (ISO18000 - 6C) protocol.
3. Operating frequencies: FCC 902 - 928 MHz, CE 865 - 868 MHz (can be adjusted via software according to the requirements of different countries or regions).
4. Operates in the wide - spectrum frequency hopping spread spectrum (FHSS) mode or fixed - frequency transmission mode.
5. Output power: Maximum 26 dBm (adjustable).
6. Built-in 3dBi circularly polarized ceramic antenna. The card-reading distance ranges from 0 m to 3.5 m*.
7. Support active mode, command mode, trigger mode, and password working mode.
8. Powered by DC 12V, with a maximum support for 24V power supply.
9. Communication interfaces support RS232, RS485, Wiegand, and trigger. 

* The effective distance is related to the protocol format, external antenna, electronic tags, and working environment.
