KD801 2.4G Omni-direction Reader

KD801 2.4G, Omni-direction Reader, has the characteristics such as wide coverage of identification, long reading distance, fast reading speed, high recognition rate, stable reliability, multiple expandability, etc.

Built-in circuit to adjust and control the reading distance and to test the signal strength of RSSI tag. The reading distance within the range of 0 to 200 meters could be managed by the software.

Application: obstacles in the communication, reading distance more than 10 meters, eg. Open channel management, industrial signal collection, personnel positioning, attendance management, goods management and monitoring, manufacturing management, transportation management , etc.


1) Working Frequency: ISM(2.4-2.48GHz ).

2) The built-in software adjusts the digital attenuator, as well as the reading distance.

3) Integrated circuit for detecting the signal strength of RSSI tag, for real-time monitoring the distance between the tag and reader.

4) Support RS-232 port, 10M/100M adaptive Ethernet communication interface.

5) Offer the input control of isolated two-way photoelectric, and the output control of two-way electric signal.

6) Users get convenient and rapid integration and application with the help of API development kit and C++, C# application routines.
