TECHNICAL DATACLEAR DETECTION
M53 model
The Clear Detection sensors are developed
for the detection of shiny and transparent
objects through the background suppression
technique.
This patented technology allows to suppress
very reflective backgrounds and, at the same
time, to detect objects with similar reflective
characteristics.
The LED emission version is recommended with
moving backgrounds, whereas the Laser version
is suitable for the highest precision detection
degrees, even of small objects, with a fixed and
reflective background.
In comparison with the previous systems
based on polarized retro-reflex photoelectric
sensors, this technology offers some additional
benefits:
•Noprismaticreflector:thereisnoneed
to have the clear object passing between
sensor and reflector so reducing installation
time and cost.
•Lessmechanicalconstraints:thedetection
can be made from either the side or from
the top without modifying any part of
the machine.
•Higherdepthoffield:theclearobject
can move or float between its background
and the sensor without adjusting the
threshold settings.
Thanks to the Teach-in push button and the background distance adjustment trimmer, it is possible to set the proper operating distance.
4 adjustable hysteresis levels allow to obtain optimal results.
The tables below show the best hysteresis levels for LED and LASER versions in different background and objects properties.
