Basic Color Sensor Overview

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

Photoelectric Basics – Distance Measuring

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 Pressure to Step Up Performance

We all know the roles of mechanical pressure gauges and switches. They either give us a visual indication of hydraulic pressure, or open or close a switch when reaching a certain threshold pressure. Electronic pressure transducers do the same, but … Continue reading

The Often Overlooked Proximity Sensor

If someone says proximity sensor, what is the first thing that comes to mind?  My guess is inductive and justly so because they are the most used sensor in automation today.  There are other sensing technologies that use the term … Continue reading
