5.2 Access guarding
Safety sensors with up to 90mm resolution are used for access guarding into danger zones. They detect
people only upon entry into the danger zone, i.e., they do not detect parts of a person or whether a person
is present in the danger zone.

5.3 Danger zone guarding
Safety light curtains can be used in horizontal arrangement for danger zone guarding - either as stand-
alone device for presence monitoring or as stepping behind protection for presence monitoring e.g. in com-
bination with a vertically-arranged safety sensor. Depending on the mounting height, resolutions of
40or90mm are used (Link destination: order guide and accessories).
