 The
mark sensor was developed to detect a specific mark,
change of color, or other process indication mark
or bar. These units are used in the detection of
labels on backgrounds, printing systems, etc where
color and or height can influence the process operation.
The optical axis match is easy, the detection accuracy
is greater than the diffuse reflection type. These
units are available in Red, Green, and Blue illumination
and can be very color specific or general purpose,
as needed. These sensors are primarily used in the
Packaging, Labeling, Printing and textile industries,
but can be used anywhere specific mark detection
is needed.
