The newest additions to the powerful ML100 Series miniature rectangular photoelectric sensors include divergent beam, or wide beam, models. Divergent beam is a type of diffuse mode which has a large beam pattern or light spot. The divergent beam's light spot is over six times as large as that of the standard diffuse mode. The diameter of the light spot for these photoelectric sensors, which are denoted by ML100-8-W…, is 170 mm x 170 mm at a distance of just 200 mm. This compares to a standard diffuse mode version ML100, which has a light spot diameter of about 25 mm x 25 mm at the same distance.
Divergent beam photoelectric sensors are also suited to detect small, glossy, or irregular objects, from wires and yarns to to tissue packing or shiny foil pouches. And they offer an alternative to retroreflective sensing, especially when there is insufficient room to mount a reflector, as shown in the above image of solar cells passing on a conveyor.
The ML100 divergent beam photoelectric sensors should be used in lieu of the older ML20 divergent models, both of which have the same mounting pattern.
