Safe switching distances
with mounting difference
The switching distance S is valid for mounting method A and B when
an
the switch is mounted on non ferromagnetic material. The min. distance
between transmitter and receiver should be 3 mm. The receiver must not
be used as mechanical stop for the transmitter.

NC contact
The NC contact requires an external series resistor R
The connection 32 (pink) must be connected to + U
The connection 31 (grey) has to be connected via a series resistor R
The value of Rv is depending on the applied voltage.
