3 Functions and features
The unit is used as an optical distance sensor�
3.1 Applications
• The optical distance sensor measures distances between 0�2 and 10 m�
• It has a background suppression at > 10���100 m�
• The measured value is shown in a 10-segment display�
• According to the set output functions 2 output signals can be generated�
4 Functions
4.1 Output function hysteresis
The hysteresis keeps the switching state of the output stable if the measured
value varies about the sensing range� Both outputs (OUT1 and OUT2) can be set
as hysteresis function. → 10.2.4 Hysteresis function
4.2 Output function window
The window function enables the monitoring of a defined acceptable range� Both
outputs (OUT1 and OUT2) can be set as window function. → 10.2.6 Window function
4.3 Analogue output function
The sensor can also output an analogue signal on output 2 (OUT2) which is proportional
to the distance. → 10.2.11 Scaling of the measuring range (analogue output).
5 Installation
5.1 Installation conditions
► Install the unit so that the object to be detected is within a measuring range of
0�2���10 m�
The unambiguity range of the sensor is fixed to 100 m� Objects within a range
> 10…100 m are suppressed�
Reflecting objects in the direct beam path of the sensor - also in the range
> 100 m – are to be avoided by the customer� Otherwise the measured
values may be ambiguous�
