Photoelectrics detect `notoriously difficult' plastic bottles.(Omron Electronics E3Z-B and E3Z-L)(Brief Article)

Control Engineering Europe, September, 2002

* Omron has recently extended its E3Z photoelectric sensor family with the E3Z-B for the detection of transparent plastic bottles. These are notoriously difficult to detect because they are clear, they do not behave as predictably as glass, and probably most significantly, the design of these bottles tends to incorporate many facets, shapes, and angles. These shapes and angles combine with the other factors to scatter light in many directions. A sensor that transmits light to these targets always has a problem in gathering enough returned light to confirm the target's presence. E3Z-B uses special optics designed to account for these factors.

The sensor is not limited to bottle detection but can be used on a variety of materials, such as films, lenses, and...
