operating instructions "object recognition sensor O2D22x“, ident no.: 704435●
The device is supplied without installation/connection accessories and software.
3.1 Accessories
www.ifm.com
→Datasheetdirect→e.g.O2D220→Accessories
4 Functions and features
The sensor uses incident light or backlight to detect the contours of an object and
compares them with the contours of one or several models in a reference image.
Depending on the degree of conformity the output can indicate if a model was
found or which one was found.

5.2 Mounting dimensions
The device is mounted using the mounting accessories or 2 M4 screws and nuts.
Holedimensions→chapter10Scaledrawing.
5.3 Installation location
Mount the sensor in front of or above the area to be monitored. The detectable►
fieldofviewsizedependsontheoperatingdistance→chapter11.1Technical
Data.
Back light or scattered light situations and continuously changing light►
conditions are to be avoided.
Do not position room lights directly facing the camera lens.►
Position the optional external illumination (e.g. O2D909) opposite the camera►
lens.
To avoid adverse effects on the image detection, avoid installation in heavily►
polluting areas of the machine.
The connected cables must be provided with a strain relief.►
6 Electrical connection
NOTE
The unit must be connected by a qualified electrician. Disconnect power before
connecting the unit.

Output signal "READY" provides the status of the sensor:
"1" after the evaluation has been carried out.
"0" as long as the evaluation is being carried out, a different application is being selected or in
case of an internal error (trigger signals are ignored).
6
Output signal "OUT" provides the result of the evaluation:
”0“ no matching model
”1“ matching model
6.3 External illumination
Connect external illumination to the trigger output of the device.►
Example Art. no.
Illumination unit, transmitter red light 630 nm O2D909
For information about the a.-m. example see:
www.ifm.com
→Datasheetdirect→O2D909
6.4 External trigger source
Connect an external trigger source (e.g. a diffuse reflection sensor) to the►
trigger input of the device.
If you use an external trigger source (e.g. a diffuse reflection sensor),
connect the trigger signal to the trigger input of the sensor. If you use
external illumination, it must be controlled via the trigger output of the
sensor. Depending on the device setting, one of four configuration
files saved in the sensor can be selected via two switching inputs.
Information about the test result is provided via switching outputs.

The evaluation time tAdepends on
the size of the field of view selected●
the model size●
the smoothing degree●
the sensitivity●
the orientation●
the number of models●
Typical evaluation times are between 50 and 800 ms.
With the corresponding unit configuration the first four applications can be selected
via the switching inputs.
