[4] Half of the opening angle (=
⍺
) of the light beams
emitted by the safety light curtain
[5] Minimum distance D between the safety light curtain
and the reflective surface
[6] Passive reflections on the surface
[7] Distance between transmitter and receiver (working distance)
[8] Hazardous area
The minimum distance D depends on two factors:
}
Working distance between transmitter and receiver
}
the maximum
of the light beams emitted by the safety light cur-
tain
at:
5° = ± 2.5° in relation to the optical axis
Minimum distance of the safety light curtain to reflective surfaces
The formula for calculating the minimum distance D is:
}
For a working distance of less than 3 m: D = 0.131 m
}
For a working distance of 3 m or more: D = working distance in m x tan
