When targets enter the detection zone, their surfaces reflect emitted light back to the detector. Engineers can control the detection area by adjusting light source angles, spacing, power levels, and beam patterns.The light source and detector components are installed in a single sensor housing, located on the same side of the object to be measured and aligned with the cross-field of view. When the target moves to this area, the light emitted by the light source is reflected back to the detector through the target surface for detection.<\/p>\n\n\n\n<figure class=\"wp-block-table has-normal-font-size\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Characteristics<\/strong><\/td><td><strong>Limitation<\/strong><\/td><\/tr><tr><td>Installation and alignment are simple.
