*1. For black paper (6% reflectance), gray paper (18% reflectance), and white paper (90% reflectance).
*2. In accordance with the FDA provisions of Laser Notice No. 50, the laser is classified as Class 1 per the IEC 60825-1:2007 and 2014 standards.
*3. Defined with 1/e2 (13.5%) of the center strength at the maximum detection distance. The sensor may be affected by light
leakage at spot sizes other than the default and when there is a highly reflective object close to the detection area.
*4. Use a power supply voltage of 12.0 VDC or higher to obtain normal output.
*5. Not including control output load current. *6. Excluding differences per Laser Notice No. 50.
