Installation
How to Prevent Mutual Interference
Series connection (Up to 3 sets, 240 beams, sensor
models ending in -01, -03, -04, and -05 are required for
series connection)
Two or more pairs of the F3SN-A can be connected in series. When
connected in series, the F3SN-A sensors generate beams in a
time-sharing manner. Thus, they prevent mutual interference and
ensure safety.
When not connected
Refer to “Precautions for All Safety Sensors” for information on
preventing mutual interference of Safety Light Curtains that are not
connected in series.
