Thanks to new technologies from SICK, TranspaTect MultiTask photoelectric sensors are now able to detect transparent and semitransparent trays and bottles without the need for reflectors, a frequent source of errors. In these applications, the reference surface is provided by a stable matte background. Sensitivity is taught in simply by pressing the teach-in button. Even high-gloss, reflective, or uneven surfaces can be detected reliably. Combined with AutoAdapt, SICK's function for continuous threshold adaptation, TranspaTect sensors provide a cost-effective and reliable detection solution in packaging processes in the food and beverage, and pharmaceuticals industries.
