Greetings,
Received a lot of help from these boards before, and hoping you guys can help me out again.
Currently working with Turck RFID Heads (TN-Q80-H1147) and Turck RFID tags (TW-L49-46-F-B128), and having a lot of issues with the individual read rates of the tags (No-Reads anywhere from 0-25% of the time, project requirement is 0.3% No Read Rate). The percentage of each head varies day to day as well (Ex: Day 1: 23.7% No Read, Day 2: 1.43% No Read). I've placed the Heads anywhere from 5mm-40mm away from the tag, and the results remain the same (relatively speaking, small changes of 1-5% are semi-noticeable in trend analysis). There are no metal or liquid obstructions between the head and the tag; The distance between all heads is greater than one meter; The tag is moving across the head at a speed of 120 feet per minute. The enviroment that the head/tag are in is extremely hot, and very dirty; Temperatures range from 100-135 degrees Farenheit.
I have spoken with Turck, and their technical support states that I'm well witin the operational limits and specifications for the equipment.
My question is thus: Has anyone had similar issues with any RFID system? Does anyone have any suggestions to try to relieve these issues I'm experiencing? Has anyone seem strange Electro-magnetic interferences cause problems with RFID read rates?
Turck TN-Q80-H1147 is the reader, and TW-L49-46-F-B128 is the tag.
