2.2.2

Distance between homologous devices

The following graphic shows the distance from the interfering devices (Ddo) according to the operating distance
(Ddo) of the couple ( TXA

– RXA ).

If different safety devices have to be installed in adjacent areas, the emitter of one device must not interfere
dangerously with the receiver of the other device.

The TXB interfering device must be positioned outside a minimum Ddo distance from the TXA

– RXA emitter-

receiver couple axis.

Fig 13 - Distance between homologous devices

This minimum Ddo distance depends on:



the operating distance between emitter (TXA) and receiver (RXA)



the effective aperture angle of the ESPE (EAA)

Fig 14 -

The following table shows, for convenience, the values of the minimum installation distances relative to some
operating distances:

Operating distance (m)

The interfering device (TXB) must be positioned at the same Ddo distance, calculated as
shown above, even if closer to TXA respect to RXA.
Installation  precautions  have  to  be  taken  to  avoid  interference  between  homologous
devices.  A  typical  situation  is represented  by  the  installation  areas  of  several adjacent
safety  devices  aligned  one  next  to  the  other,  for  example  in  plants  with  different
machines.
