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 3�5 m�
• It has a background suppression at > 3�5���4 m�
• The measured value is shown in a 10-segment display�
• According to the set output functions 2 output signals can be generated�
• O1D102: Certification 21 CFR PART 1040
The distance between the sensor and the background must be limited
to max� 4 m by the customer� Otherwise the measured value may be
ambiguous. → 5.1 Installation conditions
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).
4.4 Switch off the laser
For safety and maintenance purposes the laser of the unit can be temporarily
switched off via the input on pin 5�
