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“).

systems

robot application
5.1.1 Blanking
During fixed blanking, beams are blanked at a fixed location, see chapter 4.7.1 „Fixed blanking“.
In contrast, when floating blanking is active, the object can move in the blanked beam area, see
chapter 4.7.2 „Floating blanking“.
When reduced resolution is active, beams can be interrupted if adjacent beams are active and effective,
see chapter 4.7.4 „Reduced resolution“.
