A new patented technology is now available for the seamless detection of
b transparent bs by means of a photoelectric sensor with background suppression optic function. Glass or plastic b bs such as
bottles, vials, packaging films, etc. can be easily detected in diffuse mode even in presence of shiny and reflective backgrounds. This breakthrough
technology offers many improvements with respect to previous systems based on polarized retro-reflex photoelectric or even ultrasonic sensors:

l        No prismatic reflector: no need to have the b b passing between sensor and reflector therefore reducing installation time and costs.

l        Less mechanical constraints: the detection can be made from either the side or from the top with no need to screen or modify any bl  parts of the machine.

l        Highest depth of field: the b b can move or float in any b between its background and the sensor without any need to adjust the detection threshold.
