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.

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.

Pin Use (factory setting)

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).

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

→Datasheetdirect→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.
