Presence Check of Glass Bottles with Retro-Reflex Sensors for Transparent Objects
During the processing and filling of glass bottles in the beverages industry, the presence of transparent bottles must be reliably detected on the sorting lines in order to ensure a continuous material flow. For this purpose, retro-reflex sensors for transparent objects are mounted on the side of the feed rail. Thanks to the dynamic readjustment of the switching threshold, the sensors in stainless steel 316L housing work even with increasing contamination and dirt. Thanks to the single-lens optics, the sensor and reflector can be mounted as close to each other as desired, as they do not have a blind spot.
