Back to the Basics – What Makes Background Suppression Sensors Capable of Solving Difficult Applications?
Diffuse photoelectric sensors have been and are used to successfully solve numerous applications in automation. However, there are some applications that are too difficult or impossible to solve with standard diffuse sensors. In some cases, these difficult applications can be … Continue reading
Sometimes the things that always seem the simplest can really be the most confusing. In the world of the Photo sensor, the principle of “light-on” vs. “dark-on” is won of those things. So what am I talking about you may say? Well let’s look at both and see if I can help define these concepts.
There is always debate of which sensing technology is better to use over a broad range of applications. And for the photo sensor world, BGS or background suppression is one of these. Continue reading
Photoelectric sensors have solved numerous industrial applications over the years. There are basically three different sensing modes. The first is diffuse or reflex mode, next is retro reflective, which requires a reflector, and the third is through beam, transmitted or opposed. These field devices provide an excellent means of detecting target at a distance without contacting the object. All of the sensing modes are based on the sensor’s ability to detect a change in light reaching the sensor’s receiver. In this posting, we will review the diffuse or reflex photoelectric sensor.
