6.5 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�
Active (A)
Passive (P)
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�
