Background Suppression (BGS) Distance Measurement :
Background Suppression (BGS) sensors easily and precisely sense objects up to a
defined distance but not beyond. Light from the sensor’s emitter is reflected by an object to the
sensor’s two-segment receiver at varying angles depending on the object’s distance.
Depending on that triangulation angle and subsequently which receiver segment sees
more reflected light, the object is either detected or suppressed. Not only are background machine
panels, conveyors, and sidewalls correctly ignored, but materials and products with varying colors
and printing are seen at a consistent distance with no adjustment needed.
