Basics of Sensing Methods of Photoelectric Sensors

Sponored by Baumer

Smaller, faster, and smarter continue to be the buzzwords shaping photoelectric sensor development. A simple photoelectric sensor uses a light-emitting photodiode and light-sensing phototransistor pair to detect an object or feature within range. The light source can typically be an ordinary light-emitting diode or a laser diode.

Learn more about the photoelectric sensor types and how they are used in this informative guide.
