*1. These Sensors excluding the E3NC-LH03 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: 1220690)
      Application to the CDRH (Center for Devices and Radiological Health) is scheduled for the E3NC-LH03.
*2. The values were measured using the OMRON standard sensing object (white paper) for the E3NC-LH01, E3NC-LH02,
      and E3NC-LH02 + E39-P52.
      The values for the E3NC-LH03, and E3NC-LH03 + E39-P51 apply when an E39-R21, E39-R22, E39-RS10, or
      E39-RS11 Reflector is used.
      Other Reflectors are not recommended.
*3. 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.
*4. Measured at the rated sensing distance.
*5. The E39-P5[] contains a packing to prevent entry of foreign matter. The degree of protection between the
      E3NC-LH[][] and E39-P5[] is not specified.
