Note: Incorrect detection may occur outside the measurement range if the object has a high reflection factor.
*1. These Sensors are classified as Class 1 laser devices under IEC 60825-1 and the regulations of Laser Notice No. 50
       for FDA certification.
       CDRH (Center for Devices and Radiological Health) registration has been completed. (Accession Number:1220691)
*2. The values were measured at the center of the sensing distance using OMRON’s standard sensing object (white
       ceramic).
*3. Spot diameter: Defined at the 1/e2 (13.5 %) of the central intensity at the measurement distance.
       Measurement may be influenced if there is light leakage outside the defined region and the surroundings of the target
       object have a high reflectance in comparison to the target object.
       Also, when detecting a workpiece that is smaller than the spot diameter, a correct value may not be obtained.
