Protective field height
T
he protective field height indicates the range within which the test rod belonging to the
safety light curtain is reliably detected.
The size of the safety light curtain determines the protective field height.
Protective field width
T
he protective field width is the dimension of the light path between the twin sticks. The
maximum protective field width is limited by the scanning range.
Resolution
The resolution describes the size of the smallest object detected by the safety light cur‐
tain in the protective field. The resolution corresponds to the diameter of the test rod
belonging to the safety light curtain.
With the appropriate resolution, the safety light curtain provides finger and hand protec‐
tion.
Scanning range
The scanning range is the maximum protective field width. It is subject to the resolution
variant (14 mm or 30 mm).
The scanning range is reduced by the use of deflector mirrors and/or a weld spark
guard.
