nano-15/CI nano-15/CU nano-24/CI nano-24/CU

Product Description

The nano sensor offers a non-contact measurement of the distance to an object that has to be present within the sensor’s detection zone. Depending on the set window limits, a distance-proportional analogue signal is output. The window limits of the analogue output and its characteristic can be adjusted with the Teach-in procedure. One 2-colour LED indicates operation and the state of the analogue output.

Safety Notes

 Read the operating instructions

prior to start-up.

 Connection, installation and

adjustment works should be carried out by expert personnel only.

 No safety component in

accordance 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.

plug and colour coding of the microsonic connection cable

Start-Up

 Connect the power supply.

 Carry out the sensor adjustment in

accordance with the diagram.

Maintenance

microsonic sensors are maintenancefree. In case of excess caked-on dirt we recommend to clean 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 an object is placed in the middle of the adjusted analogue window for 30 minutes (the analogue output value is in the range of 11 to 13 mA or 4.4 to 5.6 V) 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 the object is within the adjusted window limits.

 The sensor can be reset to its fac-

tory setting (see »Further settings«).

detection zones

for different objects:

The dark grey areas are determined with a

round bar and indicate the typical operating

range of a sensor. In order to obtain the light

grey areas, a plate (100 x 100 mm) is

introduced into the beam spread from the side.

In doing so, the optimum angle between

plate and sensor is always employed.

This therefore indicates the maximum

detection zone of the sensor.

It is not possible to evaluate ultrasonic

reflections outside this area.
