1. Use for Intended Purpose
This wenglor product has to be used according to the following functional principle:
High-performance distance sensors which use the principle of transit time measurement determine the dis-
tance between the sensor and the object according to the principle of transit time measurement. These sensors
have a large working range and are therefore able to detect objects over large 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 sev-
eral sensors next to or across from each other without them influencing each other.

If the “La” pin is open or connected to negative, the laser is on.
If positive voltage is applied, the laser is off.
In the case of OPT2012 Pin “A1” can also be used as an analog output.
The reference to ground here is Pin “–” (supply voltage “0 V”).

4.3. The Control Panel
Display
Control key
A warning triangle in the display indicates that the
Sensor receives a lot of light, e.g. through a glossy
surface of the object. The measurement value could
be around 400 mm too low in this case. To find a
remedy, see the mounting instructions in case of
glossy surfaces.
5. Installation Instructions
All applicable electrical and mechanical regulations, standards and safety precautions must be adhered to
when installing and operating the Sensor. The Sensor must be protected against mechanical influences. Install
the device such that its installation position cannot be inadvertently changed. The wenglor mounting system is
recommended for installing the Sensor. In order to obtain best possible results, the device’s optics should be
aligned at a right angle to the direction in which the objects are conveyed.
At brilliant surfaces, mount the Sensor in an angle of 5° to avoid
a direct reflexion beam into the lens.

6.1. Initial Start-Up
Connect the Sensor to supply power (18 to 30 V DC). The display view appears.
The Sensor is ready for operation after 2 seconds. The following table provides an overview of typical, addi-
tional deviations during the warm-up phase.
Time (min.) 0 1 2 5 10 15
Deviation (mm) ±10 ±7 ±6 ±2 ±1 0
Switch to the configuration menu by pressing any key.
Note:
If no settings are adjusted in the configuration menu for a period of 30 s, the Sensor is automatically returned to
the read-out view. The Sensor accesses the last used menu view when a key is once again activated.
If a setting is adjusted, it becomes active when the configuration menu is exited.
The keys are used for navigation, and for configuring settings.
Important:
Do not use any sharp objects to press the keys when configuring settings, because they might otherwise
be damaged.

Example of application:
A OPT2013 is used in a high rack warehouse with varying ambient temperatures. To eliminate the temperature
drift, a reference path of 1000 mm is specified to the Sensor as the specification offset. Through an external trig-
ger Sensor, the specification offset is applied and given to the Sensor as the current distance. This ensures that
the distance tallies with the value of the reference route with every trigger signal and thus, the varying ambient
temperature has no influence on the measurement values of the Sensor.

7.7. Measure Rate
Reducing the measure rate improves resolution and reduces minimum selectable switching hysteresis.
The respective minimum and maximum values are in the table on page 6.
