IO-Link Hydraulic Cylinder Position Feedback

Guest contributor: Scott Rosenberger, Balluff Ready for a better mousetrap?  Read on….. Some time ago on Sensortech, we discussed considerations for choosing the right in-cylinder position feedback sensor.  In that article, we said: “…….Analog 0-10 Vdc or 4-20 mA interfaces probably make up 70-80% of all in-cylinder feedback in use…..” And while that 70-80% analog figure

Basic Color Sensor Overview

Guest contributor:  Jack Moermond, Balluff 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 sensors have been developed that not only can compare colors
