2-1-3 Distances from Reflective Surfaces
WARNING
Be sure to install the F3SN-B to minimize the effects of reflection from nearby surfaces.
Failure to do so may cause detection to fail and may result in serious injury.
Install the F3SN-B with minimum Distance D shown below from reflective surfaces (highly reflective
surfaces) such as metal walls, floors, ceilings, and work pieces.
Distance between emitter
and receiver
(Operating range L)
Minimum installation distance D
0.2 to 3m
0.27m
over 3m
L/2 x tan10°= L x 0.087 (m)
2-1-4 How to Prevent Mutual Interference
WARNING
The set type of the emitter and receiver must be the same.
Do not use the F3SN-B in a reflective configuration. Otherwise detection may fail.
When using multiple sets of F3SN-B, connect them and/or use light interruption panels to prevent mutual interference.
When installing two or more light curtains, considerations must be made to prevent mutual interference.
Failure to do so may cause the F3SN-B to go into a lockout condition.
