The neighbouring sets should be operated in the reverse direction with
synchronisation beams in opposition as shown below (figure 11).

The effective opening angle of the beams and the alignment tolerance for
the emitter and the receiver are approximately ±4° in compliance with the
prEN 61496-2 European project norm.
Since reflecting surfaces within the detection zone can cause light deflection
(see fig. 12) and therefore non-detection of an obstacle, a minimum
distance d should be observed.
