High-Performance Distance Sensors
2. For Your Safety
2.1 Use for Intended Purpose
The product is based on the following functional principle:
High-Performance Distance Sensor
High-performance distance sensors, which function in accordance with the transit time measuring principle,
determine the distance between the sensor and the object by measuring elapsed time from emission to
return of the light beam. These sensors have a large working range and thus detect objects over consider-
able distances. Selected sensors are distinguished by WinTec (wenglor interference free technology). This
technology allows black or shiny surfaces to be reliably detected even in extremely inclined positions. It is
possible to mount several sensors next to or across from each other without them influencing each other.
This product can be used in the following industry sectors:
• Special machinery manufacturing
• Heavy machinery manufacturing
• Logistics
• Automotive industry
• Food industry
• Packaging industry
• Pharmaceuticals industry
• Plastics industry
• Woodworking industry
• Consumer goods industry
• Paper industry
• Electronics industry
• Glass industry
• Steel industry
• Aviation industry
• Chemicals industry
• Alternative energy
• Raw materials extraction
2.2 Use for Other than the Intended Purpose
• Not a safety component in accordance with 2006/42/EC (Machinery Directive)
• The product is not suitable for use in potentially explosive atmospheres.

16 Settings
6. Settings
Object Detection Directly in Front of the Background or Underlying Surface
• Adjust and securely mount the sensor in accordance with the installation instructions making sure that the
object lies within the beam emitted by the sensor.
• Remove the object and slowly turn the potentiometer back down until the sensor is deactivated. The back-
ground or the underlying surface is now suppressed.
• Place the object back into the beam emitted by the sensor and check to determine whether or not the sen-
sor is activated again.
Detection of Objects Without Interfering Background
• Adjust and securely mount the sensor in accordance with the installation instructions making sure that the
object lies within the beam emitted by the sensor.
• Turn the potentiometer down until the sensor is deactivated and then turn it back up until the sensor is
once again activated – if necessary turn it up a bit more in order to enhance switching reliability.

High-Performance Distance Sensors
OPT2172 – 74 (Sensors with Teach-in)
The switching distance to the object can be taught in for both outputs by pressing the teach-in key on the
sensor (foreground teach-in).
Object
Sensor
Teach-in distance
Switching point
Foreground Teach-In for Switching Output 1
1. Mount the sensor in accordance with the mounting instructions.
2. Position the object in front of the sensor.
3. Press and hold the teach-in key until switching status indicator LED A1 starts blinking.
4. Release the teach-in key after 2 seconds.
5. The distance is taught in and the LED output 1 lights up in order to confirm successful teach-in.
Foreground Teach-In for Switching Output 2
1. Mount the sensor in accordance with the mounting instructions.
2. Position the object in front of the sensor.
3. Press and hold the teach-in key until switching status indicator LED A2 starts blinking.
4. Release the teach-in key after 5 seconds.
5. The distance is taught in and the LED output 2 lights up in order to confirm successful teach-in.
NOTE!
If teach-in is conducted without an object or if the object is too far from the sensor, switching
distance is set to the end of the setting range and LED A1/A2 LED blinks at a rate of 8 Hz.
The same applies to objects which are too close, but in this case switching distance is set to
the beginning of the setting range.

18 Settings via IO-Link
7. Settings via IO-Link
OPT2172 – 74 (Sensors with Teach-in)
Further settings can be entered to the sensor via the IO-Link interface.
In addition to foreground teach-in (default setting), there’s also a background teach-in option for both outputs.
Additionally, there’s also a window teach-in option for both outputs.
Process and parameters data, as well as the interface protocol and the IODD, can be found at
www.automationdirect.com in the product’s separate download area.
7.1 Background Teach-In
1. Mount the sensor in accordance with the mounting instructions.
2. Align the sensor to the background.
3. Configure or teach-in the switching output / the switching output function via IO-Link.
4. The sensor is switched as soon as an object is located between the background and the sensor.

2. Align the sensor to the background.
3. If necessary, adjust the window with the near and far switching points.

7.3 Locking
If 18 to 30 V DC is continuously applied to the teach-in input, the teach-in key is locked and protected against
inadvertent changes.
1. Change the A1/A2 pin function to external teach-in.
2. Permanently connect pin A2 to voltage within a range of 18 to 30 V DC.
3. The teach-in key is deactivated.
7.4 Switchable Emitted Light
Emitted light from the sensor can be switched off by means of an IO-Link parameter. Beyond this, the sen-
sors’ inputs can be programmed via IO-Link so that the “switchable emitted light” function can also be activat-
ed by applying 24 V to the respective input.
7.5 External Teach-In
Teach in output A1 via the teach-in input.
1. Set the A2 pin function to external teach-in.
2. Apply 24 V to pin A2 for at least 1 second, but for no more than 4 seconds.
3. As soon as voltage drops at the input, A1 is taught in.
NOTE!
Please note that during external teach-in via one of the two configurable output pins, both
independent switching points are stored to the sensor and can be read out at any time via
the process data using IO-Link. If both outputs need to be evaluated via the pins, the previ-
ously configured teach-in input must be configured once again as an output.
7.6 Error output
The error output is switched in the following cases:
• Signal from object too weak
• Incorrect installation
• The object is located outside of the working range.

20 Maintenance Instructions
7.7 Test mode
OPT2172 – 74 (Sensors with Teach-in)
A test mode can be activated for the sensors via the parameter settings. This mode simulates sensor opera-
tion, for example switching of the outputs or entry of a measured value although the sensor hasn’t detected
an actual object. The application can be run in the test mode with correctly switching outputs and display
LEDs.
8. Maintenance Instructions
NOTE!
• This wenglor sensor is maintenance-free.
• Cleaning and inspection of the plug connections at regular intervals are advisable.
• Do not clean the sensor with solvents or cleansers which could damage the product.
• The product must be protected against contamination during initial start-up.
9. Proper Disposal
wenglor sensoric GmbH does not accept the return of unusable or irreparable products. Respectively valid
national waste disposal regulations apply to product disposal.
