Safe recognition despite transparency

The production of glass was already known in ancient times. However, it was only with the further development in the form of stable bull's-eye panes in the 12th century that it was possible to let daylight into buildings regardless of the weather. Developments such as these have boosted demand and therefore also prices.

In order to be able to bring products onto the market cost-effectively, they are now manufactured in a highly automated process. Glass panes are no exception. The problem here is that glass, as a transparent material, is very difficult to detect in automated processes and can usually only be detected by sensors from a short distance. To reliably detect glass and other transparent materials such as cling film, even from greater distances, ipf electronic offers the OR270478 retro-reflective sensor. The solution works with extremely short-wave polarized UV light and therefore, unlike conventional sensors, easily recognizes transparent objects.

Feedback is provided via an exclusive-OR switching output. The connection is made via a 4-pin M8 connector.
