Product description
The pico+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 condi-
tional upon the adjusted detect dis-
tance.
Via the Teach-in procedure, the de-
tect distance and operating mode
can be adjusted. Two LEDs indicate
operation and the state of the swit-
ched output.
The pico+sensors are IO-Link-capable
in accordance with IO-Link specifica-
tion V1.0.
Safety instructions
Read the operating instructions
prior to start-up.
Connection, installation and ad-
justments may only be carried out
by qualified staff.
No safety component in
accordance with the EU Machine
Directive
Use for intended purpose only
pico+ultrasonic sensors are used for
non-contact detection of objects.
Installation
Mount the sensor at the place of
fitting.
Connect a connection cable to the
M12 device plug.

plug and colour coding of the

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.
Synchronisation
If under multiple sensor operation
the assembly distance falls below the
values shown in Fig. 2, the internal
synchronisation should be used. For
this purpose set the switched out-
puts of all sensors in accordance with
the diagram »Sensor adjustment
with the Teach-in procedure«. Then
change the multi-function output
»Com« to »synchronisation« (see
»Further settings«). Finally intercon-
nect each pin 5 of the sensors to be
synchronised.

Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface
Notes
The sensors of the pico+ family
have a blind zone, within which a
distance measurement is not pos-
sible.
The pico+ sensors are equipped
with an internal temperature com-
pensation. Due to the sensors self
heating, the temperature compen-
sation reaches its optimum work-
ing-point after approx. 20 minutes
of operation.
In the normal operating mode, an il-
luminated yellow LED signals that the
switched output is switched
through.
The pico+sensors have a push-pull
switched output.
In the »Two-way reflective barrier«
operating mode, the object has to
be within the range of 0-85 % of
the set distance.
