Leuze electronic MLC 520 EX 17
5 Applications
The safety sensor only creates square protective fields.
5.1 Point of operation guarding
Point of operation guarding for hand and finger protection is typically the most common application for this
safety sensor. In accordance with EN ISO 13855, resolutions from 14 to 40 mm make sense here. This
yields the necessary safety distance, among others (see chapter 6.1.1 "Calculation of safety distance S").
Figure 5.1: Point of operation guarding protects reaching into the danger zone, e.g. for cartoners or filling
systems
Figure 5.2: Point of operation guarding protects reaching into the danger zone, e.g. for a pick & place
robot application
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.
