DISTANCE BETWEEN REFLECTING SURFACES 

The presence of reflecting surfaces in proximity of the photoelectric barrier may generate 
spurious reflections that prevent monitoring. With reference to Figure 25, object 

A

 is not 

detected because surface 

S

 reflects the beam and closes the optical path between the 

Emitter and Receiver. A minimum distance 

d

 must therefore be maintained between any 

reflecting surfaces and the protected area. The minimum distance 

d

 must be calculated 

according to the distance 

l

 between the Emitter and the Receiver, considering that the angle 

of projection and  reception is 4°. 

 

Figure 25

 

Figure 26 illustrates the values for the minimum distance 

d

 that must be maintained when 

the distance 

l

 between the Emitter and Receiver is changed. 

 

 

Figure 26 

After installing the system, check whether any reflecting surfaces intercept the beams, first in 
the centre and then in the vicinity of the Emitter and Receiver. During these operations, the 
red LED on the Receiver should never, for any reason  switch off.
