Page 4: Identification Systems
Identification Systems HG 71450-A Identification Systems To ensure that the operating procedure is working properly, the data transmission be- tween different objects (die carrier, tools, vehicles etc.) and the control system is de- cisive. Mobile objects have to be identified and positioned fast and safely. -

Page 6: Reception Ranges And Function
Identification Systems HG 71450-A 1.3.2 Reception Ranges and Function Positioning is carried out according to the field compensation method. In the center of the reading antenna the resulting field for the transponder is erased. This data-free range D, in which no telegrams are output, has a width of 25 to 30 mm at nominal read- ing height S, see Figure 2. - Page 7 Identification Systems HG 71450-A Direction of travel F Reading antenna Line C Offset (Z) Line A Transponder Area II Area I Activation of the positioning pulse (dependent on the direction of travel F and the offset from line A) Core area of the reading antenna with explanation of the positioning pulse...
