– Parallel laser light band with an active width of 50 mm
– CCD technology permits simultaneous detection of
multiple edges
– Can be used even over large emitter-receiver distances
(recommended maximum distance: 2 m)
– Two independently configurable analog outputs,
selectable for voltage or current output
– Can be used for precision web edge guiding
– Simultaneous output of diameter and position of
objects
– Distinguishes up to 6 different objects
– Three digital outputs for binary output of the number
for the detected object
– Counting the objects in the light band
– Comparison of the number of objects in the light band
with a pre-set value and larger-smaller-equal output to
the three digital outputs

Intended use

Installation and startup may only be performed by
trained specialists with basic electrical knowledge.
Qualified personnel are those who can recognize
possible hazards and institute the appropriate safety
measures due to their professional training, knowledge,
and experience as well as their understanding of the
