Metal-free area

Direct mounting of the MDS D139 on metal is not allowed. A distance of ≥ 30 mm is
recommended. This can be achieved using spacers, see Auto-Hotspot.

Note
If the minimum guide values (h) are not observed, a reduction of the field data results. It is
possible to mount the MDS with metal screws (M5). This has no tangible impact on the
range. It is recommended that a test is performed in critical applications.
