Installing ferrite tags – TW-R…-M-B146
The TW-R10-M-B146 and TW-R12-M-B146 tags can be fitted flush to the installation environ-
ment. An undermount installation (1 mm in metal) will reduce the read/write distance by ap-
prox. 30 %.

Take read/write distances into account. Refer to the product data sheet for the values for
recommended distance (A), maximum distance (B) and the length of the transmission
zone (C) at the recommended distance.
Position the tag so that it moves past the edges of the read/write head housing during a
read or write operation (see green areas).
