The usual way of detecting objects of varying shapes, heights, or positions has been through the use of an array of single-beam photoelectric sensors or a thru-beam light grid: a photoelectric array ...
Designed to accurately detect shiny objects, the VS3 series retroreflective sensors are said to eliminate the blind response area associated with conventional photoelectric sensors. Miniature in size, ...
Photoelectric sensors and light curtain sensors are among the most commonly used sensing devices in factories. Photoelectric ...
