Q60LAF Series Laser Adjustable-Field Sensors Long-Range Self-Contained Adjustable-Field Laser Sensors Features • Long-range adjustable-field background suppression sensor detects objects within a defined sensing field, and ignores objects located beyond the sensing field cutoff • Powerful visible red laser sensing beam, class 1 and class 2 models available • Two-turn, logarithmic cutoff point adjustment for easy setting of cutoff point at long range; rotating pointer indicates relative cutoff point setting
Q60LAF Series Laser Adjustable-Field Sensors Overview The Q60LAF sensor is a full-featured adjustable-field sensor. These adjustablefield sensors are able to detect objects of relatively low reflectivity, while ignoring other objects in the background (beyond the cutoff point). The cutoff distance is mechanically adjustable, using the 2-turn adjustment screw (Figure 1). A rotating pointer indicates the relative cutoff position. (The indicator moves clockwise to show increasing distance.
Q60LAF Series Laser Adjustable-Field Sensors Color Sensitivity The effects of object reflectivity on cutoff distance, though small, may be important for some applications. The excess gain curves on page 1 were generated using a white test card of 90% reflectance. Objects with reflectivity of less than 90% reflect less light back to the sensor, and thus require proportionately more excess gain in order to be sensed with the same reliability as more reflective objects.
Q60LAF Series Laser Adjustable-Field Sensors Setting the Cutoff Distance The cutoff distance for Q60LAF sensors may be adjusted between 200 mm and 1400 mm (8" to 55") for Class 1 laser models, and between 200 mm and 2000 mm (8" to 80") for Class 2 laser models. Target To maximize contrast, position the lightest possible background to be used, at the closest position it will come to the sensor during use (Figure 5).
