Functional safety plays an important role in mechanical engineering. During the development process, standardized risk assessments are undertaken to identify and define any risks to the safety of persons and the environment. Standards set out clear requirements for the safety components used, which must then be combined with the demands of the technical specifications. Saving…
Industrial practice shows that safety applications are not the only areas where light grids can be effective. For example, they are ideal for monitoring or counting objects. Their fast response times are also an asset in final quality control, preventing this process from holding back production. Depending on the application, high resolutions, long sensing ranges…
When it comes to detecting transparent objects, the limits of conventional photoelectric sensors are soon apparent. Since clear glass or plastic absorb only a small amount of light, there is little difference between emitted and received light levels. As a result, switching signals may be unclear. Contamination by dust or moisture on the lens –…
