inductive proximity sensor / cylindrical / rectangular / non-contact

The series ferrous 3- and 4-pole comprises the ?orthodox" Inductive
Proximity Switches, which have been developed in the last decades under
consideration of the special requirements of our customers. This series is
standardized according to EN 60947-5-2.
On behalf of our clients we developed numerous different types whose
dimensions deviate from the dimensions indicated in the standard.
When applying these types of the ferrous series it has to be considered
that only ferrous metals have the indicated switching distance. When
other metals are involved, a reduction factor has to be taken into
consideration (see table and diagram).
