6.6 Distance of reflective surfaces
Reflective surfaces close to photoelectric safety sensors can disable the
safety function of the system.
The minimum distance (D) depends on the protected area width (I) taking into
consideration the projection and receiving angles.
The minimum distance (D) between reflective surfaces and the protected
area (P) must be observed. In case of non-compliance an object which
has to be detected cannot be sensed. In case of improper handling of
the product, the safety and physical integrity of operators and machinery
cannot be guaranteed.

D = minimum distance; I = protected area width (range); P = protected area
►
Once installed ensure that reflective surfaces cannot affect the function of the
photoelectric safety sensors by conducting an intentional interruption of the
light beams in the protected area.
