Proper use
Ultrasonic diffuse-reflection sensor are used as part of a higher-level overall system for the contactless detection of objects.
Function
Ultrasonic diffuse-reflection sensors work on the principle of time-of-flight measurement. The device transmits a pulse
sequence, which is then reflected by an object. The device detects the reflected wave and measures the time that has
elapsed between the transmission and reception processes. This time is used to determine the distance between the sensor
and the object. If the results correspond to the specified values, the switching output is set accordingly.
Mounting
The sensor may be mounted in any position. Make sure that it is mounted in a vibration-free and vibration-damping manner.
Also protect the device against mechanical loads such as shocks or impacts.
The transducer surface and the area of the detection lobe must be kept free. Make sure that there are no interfering objects
between the sensor and the target object inside the lobe. Otherwise, it is possible that the interfering object will cause
faulty switching. Also, avoid positioning two or more ultrasonic sensors opposite each other.
Temperature
The speed of sound in air depends on the temperature. Operation outside the specified ambient temperature is not
allowed. A temperature compensation can be switched on via IO-Link.
When temperature compensation is activated, the sensor requires about 15 minutes of warm-up time after a cold start;
only then are the measured values reproducible.
Transmission angle of the object in diffuse mode
Objects with a smooth surface are scanned reliably up to an angle of
inclination of approx. 10°. The maximum permissible tilting angle
increases for objects with a rough or heavily structured (grained)
surface.
Blindbereich im Tastbetrieb
The range 0 … 20mm in front of the sensor corresponds to the ultrasonic typical blind
range.
Distance measurements are not possible in the blind range!
The maximum scanning distance 200 mm.
Operation as a reflex barrier can be selected via IO-Link. To do this, set the value 1 to the desired distance from the reference
surface. The selected distance may vary by about 5mm. All objects that interrupt the sound between the sensor and the
reference surface are detected. The blind area may be disregarded in this case.

Cleaning
For cleaning a soft cloth moistened with soapy water is recommended.
Commissioning and adjustment
The measuring range is taught-in and the analog output is switched over by connecting the black wire (PIN 2) to the
operating voltage (PIN1).
The teach process is aborted after 20 seconds (Time Out function).
Make sure that the object to be detected is always within the scanning range limits (20 … 200mm).
In normal operation, connect the teach line to 0V to avoid interference.
1. Teach-in of a switching window
1. position the object at the switching limit 1.
2. Connect the white wire to the operating voltage for between 0.1 and 2 seconds. The LED flashes with approx.
1Hz.
3. position the object at the switching limit 2.
4. connect the white wire to the operating voltage for between 0.1 and 2 seconds.
5. the switching output is active at a distance between switching limit 1 and switching limit 2.
2. Teach-in of an object with background suppression (2-point teach)
1. position the object at the desired position.
2. connect the white wire to the operating voltage for between 2 and 4 seconds. The LED flashes with approx.
1Hz.
3. take the object out of the detection lobe so that the sensor is aligned with the background.
4. connect the white wire to the operating voltage for between 0.1 and 2 seconds.
5. the switching threshold is centered between object and background.
3. Automatic teach-in (Auto-Teach)
1. align the sensor with the background.
2. connect the white wire to the operating voltage for between 4 and 6 seconds. The LED flashes with approx.
2Hz.
3. in the next 4 to 8 seconds, guide as many objects as possible past the sensor at the desired distance.
4. the switching threshold is between object and background.
4. Change switching function (no / nc)
1. connect the white wire to the operating voltage for more than 6 seconds.
2. the switching output now works with the inverted function.
5. LED display after each teach process
If the status LED flashes twice, the teach process was successful and the sensor operates with the new values.
If the status LED flashes four times, the teach process has been aborted or the time window of 20 seconds has
been exceeded. The sensor operates with maximum switching distance as a normally open contact.
