July 26 – Day 3 – Photoelectrics and Light based Applications: Hands-on Project: Safety Controls

Photoelectrics allow non-contact inputs to drive industrial machines and process controls. Light curtains are safety control photoelectric devices that detect the presence of an operator in active work cell. In this session, photoelectric sensors and optoelectronic basics will be discussed. To illustrate some of the photoelectric sensor concepts, a safety controls device for a dc motor control will be presented as the class hands -on project.
