UHF Fixed type The 4-channel RFID reader can use up to 4 antennas, which has the advantage of extending the tag recognition range.

Used when the number of tags to read at a time is 20 or more, or the radius of the tag is large.

Communication with the host supports Ethernet and Serial Communication. You can also select when you want to activate the RFID function when the sensor operates using GPIO (General Purpose Input / Output) or to display the Tag reading result with an external LED.
