2 Safety instructions
These instructions are part of the device. They contain information and illustrations
about the correct handling of the device and must be read before installation or
use.
Observe the operating instructions.
Non-observance of the instructions, operation which is not in accordance with use
as prescribed below, wrong installation or incorrect handling can affect the safety

The device is supplied without installation/connection accessories and software.
3.1 Accessories
www.ifm.com
→ Data sheet search → 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.

→ Data sheet search → e.g. E2D110
5.2 Mounting dimensions
The device is mounted using the mounting accessories or 2 M4 screws and nuts.
Hole dimensions → Chapter 10 Scale drawing.
5.3 Installation location
►Mount the sensor in front of or above the area to be monitored.The detectable
field of view size depends on the operating distance → Chapter 11 Technical
Data.
►Back light or scattered light situations and continuously changing light condi-
tions 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.
NOTE
The voltage on pins 2, 4, 5, 6, 7 and 8 must not exceed the supply voltage on
pin 1 (U+).
►Use the same power supply and protective equipment for
●the device (e.g. O2Dxxx),
●the signal generator at the inputs (e.g. trigger switch, plc),
●the signal pick-up at the outputs (e.g. plc).
As an alternative, a diode at the switching outputs can prevent feedback
(see fig. below).

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

►For PNP units (e.g. O2D220) use trigger sensors, illumination units and control-
lers with PNP inputs and outputs.
►For NPN units (e.g. O2D227) use trigger sensors, illumination units and con-
trollers with NPN inputs and outputs.
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 search → O2D909
6.4 External trigger source
►Connect an external trigger source (e.g. a diffuse reflection sensor) to the trig-
ger 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.

Object evaluation
0: object evaluation not successful
1: object evaluation successful
Example 1 (dashed line):
last object OK, OUT = 1
next object faulty, OUT 1 → 0
next object OK, OUT 0 → 1
Example 2 (solid line):last object faulty,
OUT = 0
next object OK, OUT 0 → 1
next object OK, OUT 1

Object evaluation
0: object evaluation not successful or timeout of pulse length
1: object evaluation successful
Example 4.1:
both objects OK, OUT = 1
after expiration of tB, OUT = 0
Example 4.2:
first object OK, OUT = 1
after expiration of tB, OUT = 0
second object faulty, OUT = 0
