Installation Hints
Dimensions
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 Not correct
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

The PNP- or NPN-load will automatically be
detected.
By means of the Teach-in wire, the functions
described in the Teach-in Guide can be set-
up.
It is possible to Teach-in more sensors at the
same time by connecting the WH-wires in
parallel to the common ”-” supply.
