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.

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).
