Question
What is an effective aperture angle (directional angle)?
Answer
Safety Light Curtains F3SN/F3SH series conform to safety system construction for any category but other Line Sensors F3W-series,F3WN-series, and F3ZN-series for workpiece detection cannot be used in constructing safety systems.
In practical terms, the safety of systems is ensured with F3SN/F3SH series mainly because these products have the following four functions.
F3W-series and F3WN-series, on the other hand, do not have the design features listed under 1 to 4 below, so they cannot be used in safety applications.
Main Functions of F3SN/F3SH series
1.
The Sensor itself regularly performs diagnostic checks.
Self tests for F3SN/F3SH Series
Self diagnosis functions for F3SL Series and F3SS-AT60P
2.
The Sensor itself detects external malfunction factors (e.g., noise and external light interference) in addition to malfunctions.
3.
The Sensor has a failsafe design to always ensure a safe status (control outputs OFF) even if the Sensor is malfunctioning.
4.
The control outputs always use light-ON operation.
(Note: On the other hand, the potentially dangerous option of dark-ON can be selected for F3W-series, F3WN-series, and F3ZN-series.)
