Mounting
Leuze electronic MLC 530 39
At an installation height of 300 mm, a receiver with 40 mm of resolution and 1350 mm of protective field
height as well as activated reduced resolution is also suitable.

WARNING
Failure to maintain minimum distances to reflective surfaces may result in serious injury!
Reflective surfaces can indirectly deflect the transmitter beams to the receiver. In this case, interruption
of the protective field is not detected.
 Determine the minimum distance a (see figure 6.2).
 Make certain that all reflective surfaces are the necessary minimum distance away from the protective
field according to prEN IEC 61496-2 (see figure 6.3).
 Check that reflective surfaces do not impair the detection capability of the safety sensor before start-
up and at appropriate intervals.
