RFID tags and reader...

[ORSO2001]

dears All,

for a new project (feeding system of plastic granules) customer has many feeding sources (130 fixed pipes) and many material receivers (70) that can be connected with the material sources by flexible pipes.

I (customer) need to be sure that the flexible pipe is connected/coupled with the right fixed pipe...in some factory I saw that was used a RFID tag (key shaped) for the flexible pipe and a RFID reader (with hole for the key tag) for the fixed pipe; these last were connected with a "concentrator" connected by RS485 with a PLC.

has someone a suggestion where ask for this kind of solution (RFID)...and/or has already used this with Unistream?

thanks
