Product Description
A family of extended range
inductive proximity switches
in industrial stainless steel
housings. They are able to
handle applications where
high sensing range is request-
ed. Outputs are open collector
NPN or PNP transistors.
Available with cable and M8
plug.

Installation Hints
Relief of cable strain Protection of the sensing face Switch mounted on mobile carrierTo avoid interference from inductive voltage/
current peaks, separate the prox. switch pow-
er cables from any other power cables, e.g.
motor, contactor or solenoid cables Incorrect
Correct
The cable should not be pulled A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the
cable should be avoided
