2.2.1 Minimum distance from reflecting surfaces
Reflecting surfaces placed near the light beams of the safety device (over, under or laterally) can cause passive
reflections. These reflections can affect the recognition of an object inside the controlled area. Moreover, if the RX
receiver detects a secondary beam (reflected by the side-reflecting surface) the object might not be detected, even
if the object interrupts the main beam.
Fig 13 - Distance from reflecting surfaces
It is important to position the safety light curtain according to the minimum distance from reflecting surfaces.
The minimum distance depends on:
 operating distance between emitter (TX) and receiver (RX);
 real aperture angle of ESPE (EAA); especially:
