CK-FR01-A01 is a high-frequency RFID tag reader with a working frequency of 13.56MHZ. It supports the reading of I-CODE 2, I-CODE SLI and other international standard protocol format tags that conform to ISO15693. The radio frequency part of the communication protocol is integrated internally. Users only need to receive data through the RS485 communication interface to complete the reading operation of the tag without understanding the complex radio frequency communication protocol. With Auto-turning automatic tuning circuit, it can automatically adjust the circuit parameters when working in different environments, minimize the influence of the external environment on the reading distance, and enhance its own anti-interference ability. It is widely used in logistics and warehouse management. Process control, robotic arm site
