42BT Background Suppression
Many today's material handling applications requires reliable detection objects that fall close surface which must ignored. Standard diffuse sensors will often trigger these backgrounds, especially when they light shiny surface. Economics typically permit placement reflectors that required retroreflective sensors. these situations desirable background suppression sensor. 42BT photoelectric sensor uses triangulation method mechanically adjust sensing angle, thereby, ensuring reliable detection target while ignoring background. Using sensitivity adjustment cover, desired sensing range dialed meet specific application. 42BT available either (3.3ft) (6.6ft) sensing range. applications where sensing distances much shorter RightSight background suppression sensor recommended. These sensors offer fixed 50mm (2in) 100mm (4in) sensing range. Background suppression sensors ideal applications where desirable detect reflections from target surface, ignore reflections from background surfaces objects directly behind target. Adjustable background suppression allows user move focal point emitter receiver cross beam pattern. This allows optimal sensor location removal background very close target object.
