5-1-3. Distance from Reflective Surfaces
Install the F3SG-SR so that it is not affected by reflective surfaces. Failure to do so may
hinder detection, resulting in serious injury.
Install the sensor system at distance D or further from highly reflective surfaces such as metallic walls,
floors, ceilings, or workpieces, as shown below.
