Function: RAL150-IR/32/98

Slot grid sensors are ideal for filling and counting objects in feed devices. In contrast to standard photoelectric slot sensors, the slot grid sensors have an entire field for object detection with a maximum response time of 100 μs and a minimum object size of 1 mm. When using dynamic mode, only moving objects are detected.
