2. For Your Safety
2.1 Use for Intended Purpose
The product is based on the following functional principle:
Reflex Sensors with Background Suppression
Reflex sensors with background suppression analyze the light reflected from objects. As these sensors work
according to the principle of angular measurement, the color, shape and surface characteristics of the object
have almost no influence on the detection range. Even dark objects can be reliably detected against a bright
background. The output is switched as soon as an object passes the selected range.
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.
• The product may only be used with accessories supplied or approved by wenglor, or combined with ap-
proved products. A list of approved accessories and combination products can be accessed at
www.wenglor.com on the product detail page.
DANGER!
Risk of personal injury or property damage in case of use for other than the intended
purpose!

16 Settings
6. Settings
The switching distance to the object can be taught in for both outputs by pressing the teach-in key on the
sensor (default setting is foreground teach-in).
Teach-In for Switching Output 1
1. Mount the sensor in accordance with the mounting instructions.
2. Press and hold the teach-in key until switching status indicator LED A1 starts blinking.
3. Release the teach-in key after 2 seconds.
4. The distance is taught in and the LED at output 1 lights up in order to confirm successful teach-in.
Teach-In for Switching Output 2
1. Mount the sensor in accordance with the mounting instructions.
2. Press and hold the teach-in key until switching status indicator LED A2 starts blinking.
3. Release the teach-in key after 5 seconds.
4. The distance is taught in and the LED for 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.
7. Functions Overview
Further settings can be entered to the sensor via the IO-Link interface or NFC.
7.1 Teach Mode
7.1.1 Foreground Teach-In
Teaching in progress while the sensor is focused on the object. The switching distance is then automatically
set to a distance which is slightly greater than the clearance between the sensor and the object. The sensor
is thus activated for all objects whose distance to the sensor is equal to or less than the distance to the object
used for the Teach-In procedure.

Reflex Sensors with Background Suppression High-End with Teach-in
7.1.2 Background Teach-In
Teach-In is performed while the sensor spot is aligned to the background. The switching distance is then au-
tomatically set to a distance which is slightly less than the clearance between the sensor and the background.
The sensor is thus activated whenever an object is located between the background and the sensor.

7.2 Pin Function, I/O2
The function of I/O2 can be configured either as an output or an input.
7.2.1 Input External Teach-In
Teach in output A1 via the teach-in input.
1. Set the E/A2 pin function to external teach-in.
With Ub setting active (default):
2. Apply 18…30 V to pin E/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.
With Ub setting inactive:
2. Disconnect pin I/O2 or connect it to 0 V for at least 1 second, but for no more than 4 seconds.
3. As soon as voltage is applied to the input, O1 is taught in.
Locking
If the teach-in input is continuously activated, the teach-in key is locked and protected against inadvertent
changes.
1. Change the E/A2 pin function to external teach-in input.
With Ub setting active (default):
2. Permanently connect pin E/A2 to voltage within a range of 18 to 30 V DC.
3. The sensor is protected against inadvertent changes caused by the teach-in key.
With Ub setting inactive:
2. Permanently disconnect pin I/O2 or connect it to 0 V.
3. The sensor is protected against inadvertent changes caused by the teach-in key.

19
Reflex Sensors with Background Suppression High-End with Teach-in
9. NFC
The devices can be set up and their parameters can be configured via the NFC interface with the help of an
Android smartphone and wenglor’s “Sensor Configurator” app. Process data cannot be read out via NFC but
they’re available via IO-Link.
The wenglor app can be downloaded free of charge from the Google Play Store. Download the app and
follow the installation instructions.
Scan the code below to access the wenglor app directly.
The settings are selected via the app and are then transmitted to the sensor.
With the “Read” or “Write” mode activated, hold the smartphone’s antenna just above the sensor’s active
NFC sensing face.
NOTE!
• NFC antenna position varies from one smartphone to the next.
• Refer to the smartphone’s operating instructions in order to determine the antenna’s
exact position.
If a connection isn’t established immediately, move the smartphone across the sensing face until connection
is successful.
The sensor doesn’t necessarily have to be connected to supply voltage for data transmission,
i.e. transmission is also possible in the de-energized state.
10.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.

20 Proper Disposal
11.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.
