Safety Notes
These photoelectric sensors may not be used in
applications where personal safety depends on
proper function of the devices (not safety
designed per EU machine guideline). Read
these operating instructions carefully before
putting the device into service.
Exempt Group according to EN 62471:2008.
DO NOT STARE INTO THE LIGHT BEAM!
Danger of glare and irritation!
The sensor must be installed so that no direct
looking into the light source is possible even
during operation.
The CE Marking confirms that our products
conform to the EC Directives 2004/108/EEC
(EMC) and the EMC Law.
In our EMC Laboratory, which is accredited by
the DATech for Testing of Electromagnetic
Compatibility, proof has been documented that
these Balluff products meet the EMC require-
ments of the harmonized standard EN 60947-5-2.

Installation
Attention!
Do not stare into the light beam.

Settings
Standard setting
1. Position the emitter and receiver at the desired
distance.
2. Turn potentiometer clockwise to max. sensitivity (grea-
test range)
3. Determine the switch-on and switch-off point of the
output (yellow LED): Move the sensor in all directions
so that the yellow LED goes on and off again.
4. Install the sensor in the middle of the determined
switching points. The sensor is ideally aligned when the
yellow LED is on and indicates reliable function.
Fine adjustment for detecting small objects
1. First perform the standard setting (see above).
2. Then turn the potentiometer counter-clockwise until the
yellow LED goes off. The reflector is no longer
detected.
3. Now turn the potentiometer slowly clockwise until the
yellow LED goes on. The reflector is detected again.
Now even small objects can be sensed.
