Within the photoelectric-sensor arena, the diffuse sensing mode has become much more prevalent with the development and refinement of background suppression-the ability of a sensor to see an object and ignore the reflective surface directly behind it. This is a contributing factor to the diffuse mode's emergence as the preferred method of photoelectric sensing.
In many cases, the selection of a sensor, particularly in difficult applications, is the result of trial and error. Although the applications for diffuse-mode photoelectric sensors are diverse, the most effective selection and use of the technology requires an understanding of the operating principles and how the fundamentals relate to the application. In no area of diffuse sensing is this truer than in background suppression.
Automation professionals favor complete end-to-end solutions. But to meet the unique requirements of specific applications, engineers turn to tailored subsystems, which optimize the overall system, reduce commissioning time, and cut costs.
Today's industrial automation market continues to be driven by a complete-solution focus, with emphasis on reduced cost of ownership and increased value for the user. Increasingly, though, users turn to subsystems to save commissioning time and reduce costs.
