 Distance from Reflective Surfaces
Install the sensor system so that it is not affected by reflection from a glossy surface.
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.
 Mutual Interference Prevention
Mutual interference is prevented in up to three sets, using interference light detection and cycle shift
algorithm.
If four or more sets of F3SJ-Bs are installed, arrange them so that mutual interference does not occur.
If two sets are installed near each other, reflection from the surface of the F3SJ-B may cause mutual
interference. When mutual interference occurs, the safety outputs are turned OFF in a moment or the
F3SJ-E/B enters lockout state.
Combining countermeasures 1 to 3 shown below is effective.
1. Install a physical barrier between two sets
