What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).

AutomationDirect has expanded its photoelectric sensor offering to include OPT series short and long range distance sensors. Available with either Class 1 or Class 2 laser options, the distance ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
