Ultrasonic Sensors
The nano sensor offers a non-contact
measurement of the distance to an
object which must be positioned
within the sensor’s detection zone.
The switched output is set conditional upon the adjusted detect distance.
Via the Teach-in procedure, the detect distance and operating mode
can be adjusted. One 2-colour LED
indicates operation and the state of
the switched output.

dance with the EU Machine Directive.
Use for intended purpose only
nano ultrasonic sensors are used for
non-contact detection of objects.
Installation
Mount the sensor at the installa-
tion site.
Connect a connection cable to the
M12 device plug.
The assembly distances shown in fig.
2 for two or more sensors should not
be fallen below in order to avoid mutual interference.
Start-up
Connect the power supply.
Carry out sensor adjustment in
accordance with the diagram.

Operating modes
Three operating modes are available
for the switched output:
Operation with one detect point
The switched output is set when the
object falls below the set detect
point.
Window mode
The switched output is set when the
object is within the set window.
Two-way reflective barrier
The switched output is set when the
object is between sensor and fixed
reflector.
Maintenance
microsonic sensors are maintenancefree. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface.
Notes
Every time the power supply is
switched on, the sensor detects its
actual operating temperature and
transmits it to the internal temperature compensation. This results
in a slight correction of the analogue output value after 45 seconds.
If the sensor was switched off for
at least 30 minutes and after power on the switched output is not
set for 30 minutes a new adjustment of the internal temperature
compensation to the actual mounting conditions takes place.
The sensors of the nano family
have a blind zone. Within this
zone a distance measurement is
not possible.
In the normal operating mode, an il-
luminated yellow LED signals that the
switched output is switched
through.
In the »Two-way reflective barrier«
operating mode, the object has to
be within the range of 0-85 % of
the set distance.
In the »Set detect point - method
A« Teach-in procedure the actual
distance to the object is taught to
the sensor as the detect point. If
the object moves towards the
sensor (e.g. with level control) then
the taught distance is the level at
which the sensor has to switch the
output.
If the object to be scanned moves
into the detection area from the
side, the »Set detect point+8 % method B« Teach-in procedure
should be used. In this way the
switching distance is set 8 % further than the actual measured distance to the object. This ensures a
reliable switching distance even if
the height of the objects varies
slightly.

detection zones
for different objects:
The dark grey areas represent the zone
where it is easy to recognise the normal
reflector (round bar). This indicates the typical
operating range of the sensors. The light
grey areas represent the zone where a
very large reflector - for instance a
plate - can still be regognized. The
requirement here is for an optimum
alignment to the sensor. It is not
possible to evaluate ultrasonic
reflections outside this area.
