The Inductive Proximity Switches of the Type All Metal Standard IAD / AHM have an iron less coil in connection with an ironless housing. Therefore this type has the
-reduction factor 1 for all metals (A)
-magnetic field-resistance to over 150 mT (M)
and properties, which exceed the requirements stipulated by| DIN EN 60 947-5-2 by far such as
-increased switching distance with the flush mounting version
-increased ambient temperature range - 25 ... + 85 °C
-increased switching frequency of over 10 kHz (H)
The increased maximum switching frequencies (maximum operating frequencies) of over 10 kHz have to be considered in particular. Unlike these, conventional proximity switches with maximum operating frequencies of 200 Hz to 2 kHz are comparably slow.
Apart from the high maximum possible operating frequencies these sensors also offer very short operating times < 50 jjs (instead of 0.2 to 5 ms with conventional proximity switches). The LED displays of the Q40 and Q80 versions in the metal housing lead into bright lightened printed-circuit boards, which can be well seen by the operator.
