Microsonic pico+15/TF/F Operating Manual

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 switching output is set conditional
upon the adjusted detect distance.
The ultrasonic transducer surface of
the pico+ sensors is laminated with a
PTFE film. The transducer itself is
sealed against the housing by a joint
ring. This composition permits measu-
rement in up to 0.5 bar over pressure.
Via the Teach-in procedure, the detect
distance and operating mode can be

of the switching output.

Safety Notes
Ԏ Read the operating manual prior
to start-up.
Ԏ Connection, installation and ad-
justments may only be carried
out by qualified staff.

Proper Use
pico+ ultrasonic sensors are used for
non-contact detection of objects.

Synchronisation
If the assembly distance of multiple
sensors falls below the values shown
in Fig. 2, the internal synchronisation
should be used (»Sync« must be swit-
ched on, see Diagram 1). For this pur-
pose set the switching output of all
sensors in accordance with Diagram 1.
Finally interconnect 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
Ԏ The sensors of the pico+ family
have a blind zone, within which a
distance measurement is not possi-
ble.
Ԏ The pico+ sensors are equipped
with an internal temperature com-
pensation. Due to the sensors self
heating, the temperature compen-
sation reaches its optimum wor-
king-point after approx. 120 se-
.

Ԏ In the normal operating mode, an
illuminated yellow LED signals that
the switching output is switched
through.
Ԏ The pico+ sensors have a push-pull
switching output.

the set distance.
Ԏ 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
(see Fig. 3).
