Detecting hot objects in industrial applications can be quite challenging. There are a number of technologies available for these applications depending on the temperatures involved and the accuracy required. In this blog we are going to focus on infrared temperature … Continue reading
In the past, color sensors emitted light using red, green and blue LEDs’. The sensors were then able to distinguish colors using the RGB components of the reflected light back to the sensor’s receiver. As technology has progressed true color … Continue reading
Some photoelectric applications require not only knowing if the object is present or not but exactly where the object is while providing a continuous or dynamic value representative of the objects location. For instance, if a robot is stacking a … Continue reading
The foundation of a photoelectric sensor is light! Without the light you have a housing with some electronics in it that makes an interesting object to leave on your desk as a conversation starter. Is all light the same? Does … Continue reading
On Sensortech, we have posted several entries about the trend toward miniature sensors including, Let’s Get Small: The Drive Toward Miniaturization and Trending Now: Miniature Sensors. At the end of January Balluff attended SLAS in San Diego, CA and saw this trend firsthand. Automation … Continue reading
Photoelectric sensors are used in a wide variety of applications that you encounter every day. They are offered in numerous housing styles that provide long distance non-contact detection of many different types of objects or targets. Being used in such … Continue reading
In automated manufacturing, part quality issues are a weekly discussion and this continues to be true in most weld shops across North America. One of the more common issues that I encounter in discussions with customers involves nuts being welded … Continue reading
