1. Use for Intended Purpose
This wenglor product is intended for use in accordance with the following functional principle:
High-Performance Distance Sensors
This product group includes high-performance sensors for measuring distance, which function in accordance
with various principles in scanning mode operation. High-Performance Distance Sensors are especially fast or
accurate, or have large working ranges. They’re extremely well suited for demanding applications. Even black
and glossy objects can be reliably detected. Ethernet technology is integrated into selected sensors.

6. Installation Instructions
During use of the sensor, applicable electrical and mechanical regulations, standards and safety precautions
must be adhered to. The sensor must be protected against mechanical influences.
When installing the sensor it must be ensured that direct eye contact with the laser beam is avoided. The laser
warning must be plainly visible.
When installing the sensor it must be ensured that the measuring beam is exactly perpendicular to the surface
to be measured in order to assure accurate measurement results. Tilting results in a geometrically longer
measuring path.
Moving or Striped Objects
If moving or striped objects will be measured, the sensor head should be mounted with its long side perpen-
dicular to the motion of direction or the stripes. In this way, better measurement results can be achieved in the
corners because shadowing is avoided:

7. Initial Start-Up
Two connector plugs are integrated in to the sensor’s housing. The 8-pin plug supplies the sensor with +24 V
operating voltage, whereas communication for parameters configuring and process data is conducted via the
4-pin socket. We recommend the exclusive use of Ethernet switches in order to optimize data communication.
Please note: If Gigabit Ethernet cards are used, the polarity of the Tx and Rx conductors might not be correctly
detected. Connecting sensors directly may result in complications. With an Ethernet crossover cable (cross-
link), the sensor functions flawlessly via a PC network card. As an alternative, a commercially available 100 Mbit
Ethernet switch can also be used.

8. Function Descriptions
PNCB High-Performance Distance Sensors work with a high resolution CMOS line array and determine dis-
tance by means of an angular measurement at a sampling rate of up to 30 kHz. The sensor is equipped with
integrated electronics and no additional controller is required as a result.
Ascertained distance values are read out as process data via the interface and at the analogue output with16-
bit resolution.

The diffusely reflected light from the measuring point is decisive for the measurement. Inadequate intensity
of the remitted light is indicated by an LED signal lamp on the sensor’s control panel. In the event of minimal
remission, the sensor automatically reduces its sampling and output rates, in order to provide accurate mea-
surement results. Signal strength is indicated on the website as a percentage (see “Status Display” in section
“9.1. Page Layout (website)” on page 22 ).
Not only does the laser spot produce an illuminated pixel on the CMOS line array, it also generates an intensity
curve which is distributed over several pixels. This intensity curve is called the peak, and ideally it’s steep at
both ends, monotonically non-decreasing and symmetrical. The curve depends on distance, internal optics
and the surface of the object to be measured. The evaluation method is decisive with regard to attainable mea-
suring accuracy. Some surfaces require an evaluation method which is especially suited to them.

17
The following peak evaluation methods (algorithms) are available:
8.1. Evaluation method
8.1.1. Center of Gravity (Cog)
The Cog evaluation method calculates the peak’s center of gravity, whose×-coordinate is the sought crude
result. The peak has to be separated from the “sink” for the purpose of center of gravity analysis, which neces-
sitates calculation of the so-called sink height.
background level
sink height
measured value
Sink height is the mean value of all pixel intensities and is thus somewhat higher than the background level.
All pixels to the left and to the right of the maximum, whose intensity is greater than the sink height, are used
in order to calculate the center of gravity. With 16-bit resolution, the measured values are highly precise thanks
to this evaluation method.
8.1.2. Edge Evaluation
In this evaluation method, the peak's edges are evaluated. The advantage of this evaluation method is the fact
that the peak’s asymmetrical crests, caused for example by speckle effects resulting from a sheet metal panel,
are excluded from the evaluation.
measured value
With edge evaluation as well, the measured values achieve highly precise 13-bit resolution.

8.2. Measuring Accuracy and Error Influence
8.2.1. Calibration Report
A calibration report is included with the sensor, which graphically represents linearity error as a percentage
for the measured value on a matte white surface.

8.2.2. Surface Material
Possible objects to be measured include all sorts of materials such as metal, plastic, ceramic, rubber and pa-
per. Suitability for use only needs to be tested individually for highly reflective surfaces and liquids.
8.2.3. Surface Damage on the Object to be Measured
A scratch on the surface of the object to be measured which runs perpendicular to the axis of the lens may
cause stronger light emissions, whose maxima are located next to the center of the spot. An incorrect distance
is simulated as a result.
If a moving object is involved, the mean (integral) measured value remains constant when the damaged sur-
face is scanned, i.e. the positive and negative edges cancel each other out due to the damage.
Undesired deflection can be minimized by selecting a suitable average filter.
8.2.4. Extraneous Light
When installing the sensor it must be assured that no direct or reflected sunlight can shine into the receiver
optics. Where difficult applications are involved, this “extraneous light” may interfere with measured value re-
cording. The measuring point should be correspondingly shaded in such cases.
8.2.5. Changes in Remission
The sensors are equipped with luminous intensity control which is automatically adjusted to the level of remis-
sion from the object to be measured. If remission from the surface changes during measurement, the sensor
compensates for any fluctuation. By selecting a fixed sampling rate, measured values remain accurate even if
surface remission changes.
8.2.6. Dependence of Measurement on Angle
Measurement is minimally dependent on angle if the sensor is not aligned at a right angle to the object to be
measured. Tilting the sensor results in a greater distance to the object. This change in distance can be set to
zero by means of a corresponding offset shift.

9. Settings
There are several different ways to enter settings to the device:
• Via the integrated website, with which PNBC Sensors are equipped. This website functions independent of
the operating system and the sensor can be configured via a standard browser.
• The web-based configuration interface is not required for normal operation with a controller (the default IP
address is listed in section “6.1. Default Settings” on page 15).
• With the help of w-Teach configuration and display software which is available for download from
www.wenglor.com
• Using the function block for simplified incorporation of PNBC Sensors into an S7 controller – also available
for as a download
Settings are explained below based on the descriptive example provided by the website which is integrated
into the sensor.
Attention:
If the sensor is connected to a controller, the settings which have been selected via the website are overwritten
by the controller.
Accessing the Website
Start the web browser. Enter the sensor’s manually selected IP address to the address line in your browser and
press the enter key. In order to ensure that the browser displays the current settings on the website, the website
has to be automatically reloaded whenever changes are made. This setting must be changed in a browser-
specific manner which is described here using the Internet Explorer as an example. Select Every time I visit
the webpage under Tools Internet options General Settings. Otherwise, changes might not be correctly
displayed via the website.
