Instruction Manual DS2
2.2.2. Minimum distance from reflecting surfaces
Reflecting surfaces placed near light beams of the AREAscanTM device (over, under or laterally)
may cause passive reflections that can compromise the detection of an object inside the controlled
area (see Fig.1).
Fig. 1
However, the object may not be detected if the receiver detects a secondary beam (reflected by the
side-reflecting surface), even if the entering object interrupts the main beam.
It is thus important to position the units at the correct distance from any reflecting surface:
The minimum distance depends on:
- device operating distance
- reflecting surface nature
- position of the object inside the sensitive area
It is necessary to evaluate this distance on the field according to the operating conditions; however
a minimum distance from the reflecting surface of about 0.5 m is suggested.
