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 conditional upon the adjusted detect distance. Via the Teach-in procedure, the detect distance and operating mode can be adjusted. Two LEDs indicate operation and the state of the switched output. The pico+sensors are IO-Link-capable in accordance with IO-Link specification V1.0.

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 outputs 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 interconnect each pin 5 of the sensors to be synchronised.

Fig. 2: Assembly distances

Maintenance

microsonic sensors are maintenancefree. 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 possible.

 The pico+ sensors are equipped

with an internal temperature compensation. Due to the sensors self heating, the temperature compensation reaches its optimum working-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.

detection zones

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

for different objects:

possible to evaluate ultrasonic

reflections outside this area.

■ 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
