LRD2100 and LRD3100
Butt splices have no e ect on sensor operation when:
Butt splice edges are located under labels
AND
e sensor is triggering on the leading edge of the labels for registration

e sensor is triggered by changes between more and less material. When a
splice is present, it adds another set of transitions between more and less mate-
rial.
Once the sensor triggers on a label, any subsequent transitions to more material
are ignored.
After the sensor has triggered on a label edge, it will indicate the end of the
label at the next transition to less material. For this reason, detection of leading
edges of the labels is una ected, but the end of the label will be indicated at the
trailing edge of the splice. Using the leading edge to control registration assures
no e ect from splices.

LRD6110 and UltraLRD
e LRD6100 and UltraLRD measure the total thickness of material in the
sensor fork. When the thickness exceeds the trigger point, the sensor indicates
a label. Once the trigger point is exceeded, any further increases in thickness do
not a ect the output.
Splice material will usually exceed this trigger point and cause the sensor to
indicate the presence of a label while the splice is present, even if it is in the gap
between labels.
Any labels which have leading edges over a splice will not be detected.
Sample waveforms:
If the splice is under only one label, the splice will not be detected.
