These proximity switches
must not be used
in applications where the
safety of people
is
dependent on their functioning. Terms of
delivery and rights to change design reserved.
Max. distance / sensitivity
Remove target and background.
Execute Teach 1.
Place emitter and receiver so that
no light is transmitted. Execute
Teach 1.
Min. distance / sensitivity
Place fiber-optic head about 5 mm
from white paper. Execute Teach
1.
Place emitter and receiver in
direct contact so that a maximum
of light is transmitted. Execute
Teach 1.
Remote teach launching
Launch by L signals or by closing
a contact at the “Teach” input.
Teach 1
: Remove target.
: Position target.
Send pulses T1 and T3.
Timing:
T1, T3 = 0.5 ... 2 sec
T2 = 1.5 ... 2 sec
Teach 2
: Position target and back-
ground.
: Remove target.
Send pulse T1, then
: Remove target, leave back-
ground in position.
: Position target.
Send pulse T3.

Device mounting
Mounting of the device is most
easily effected by snapping
/
onto a top-hat rail (according
to DIN / EN 50022).
Alternatively, fixing can be
effected using M3 screws
through the fixing holes
provided.
To remove the device from the rail,
push towards the optical fiber ,
and lift .
Fixing the optical fibers
Lift catch
.
Insert the optical fibers through
the two holes
provided into
the device.
Lower catch
.
Important
:
When inserting the optical fibers,
the resistance of the device’s in-
ternal O-ring seal must be over-
come.
The optical fibers must be fed
right to the stop without fail.
The optical fibers must not be
crushed.
The sequence (emitter /
receiver) is usually immaterial,
however:
With coaxial optical fibers, the
optical fiber bundle
must be
connected on the receiver side
. The emitter and receiver
openings are marked with arrows
on the housing.
