(1) Nominal Scanning Range of the FF-SYA14 light curtain: 6 m (19.7 ft),
Nominal Scanning Range of the FF-SYA30 / FF-SYA60 light curtains: 20 m (65.6 ft),
Nominal Scanning Range of the FF-SYA234 multibeam systems for access detection: 80 m (262.4 ft)
To guarantee this nominal scanning range and the decreased scanning ranges, the devices have a greater effective
scanning range with up to 20 % variations from the nominal values.
