The max. gap without cover strip is 0.2 mm + 0.1 / -0mm. When using cover strip, the gap is
reduced by the thickness of cover strip including its cover strip. The sensor must not touch the
magnetic strip.

2.6.4 Necessary measures:

The sensor should be positioned well away from cables with interference; if necessary a
protective screen or metal housing must be provided. The running of wiring parallel to the
mains supply should be avoided.

Contactor coils must be wired with spark suppression.
2.6.5 Maintenance
We recommend cleaning the magnetic strip's surface from time to time with a soft rag. This
avoids dirt(dust, chips, humidity ... ) sticking to the strip.
