2.2.1 Minimum distance from reflective surfaces
Reflective surfaces close to the beams emitted from the protective device (whether from
above, below or from the side) can cause passive reflections. These passive reflections can
adversely affect how the object is detected within the protected area. If the receiver RX
detects a secondary beam (reflected by the side-reflecting surface), the object may not be
detected even if it interrupts the main beam.
