In combination with a reflector, the Reflex Array MultiTask photoelectric sensor detects leading edges of small, flat, transparent or unevenly formed objects on conveyor belts within its light array. Detection takes place regardless of where and how the objects are positioned on a conveyor belt. The photoelectric sensor reliably detects objects such as glass bottles and polybags. The Reflex Array can even detect perforated objects easily without triggering multiple switching operations. This reduces the overall costs and accelerates the commissioning process. Compared to other solutions that involve use of individual photoelectric sensors or small light grids, Reflex Array offers substantial cost benefits.
