Safety field
The safety field is the area of the ESPE where an object (e.g. person or object) is detected according to the
resolution.
Safety field height
The safety field height describes the dimension of the range within which a standardized test object (test rod)
is recognized by the ESPE. It depends on the size of the safety light curtain.
Safety field width
The safety field width is the clearance between the emitter and receiver. The safety field width must not
change during operation.
Range
The range is the mechanically usable distance between the emitter and receiver. Using path-folding mirrors
reduces the range.
Resolution
The resolution of a safety light curtain is the object size that can be recognized at any point within the safety
field, and which thus results in a shutdown command. It corresponds to the diameter of the corresponding
test rod and, with the SEFG, can be 30 mm (hand protection) or 14 mm (finger protection).
