42BC Long Range Background Suppression
42BC photoelectric sensor offers high performance background suppression performance sensing ranges (6.6ft). This type sensing capability desirable applications where standard transmitted beam retroreflective sensing practical easy access both sides target when economics major factor. 42BC 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. 42BC 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. Similar long range sensing distances solved with 42BT photoelectric sensor also. This sensor provides smaller package style space critical installations.
