Ranges include up to 1 m (3.28')(diffuse reflective), 5 m (16.4') (retroreflective) or 25 m (82') (thru-beam). Features push-button calibration and a microprocessor that monitors signal strength and gives a warn-ing of signal degradation due to dirt accumulation or other causes.
By combining long-range sensing with automatic dynamic calibration and a damage-resistant mounting option, new OL photoelectric sensors from efector (Exton, PA) are said to solve many of the problems typical in conveyor applications.
