Safety Advisory
Laser protection regulations: The transmitter
and the laser light barrier comply with laser
protection class II in accordance with DIN EN
60825-1/94. Therefore no additional protective
measures are necessary for operation.
These Photoelectric Sensors are not suited for
safety related applications.
The CE-Marking means that our products
conform to the requirements of the EC Guidelines
89/336/EWG (EMC) and the EMC Statute.
Testing in our EMC Laboratory, which is accredited by
DATech for Testing of Electromagnetic Compatibility, has
shown that these Balluff products satisfy the EMC
requirements of the following Generic Standards:
− EN 50 081-2 (Emission) and
− EN 50 082-2 (Noise Immunity)
Controls
Yellow LED
Output function indicator (receiver only): The yellow LED
ON indicates that the output is active
Green LED
STABILITY LED (receiver only): The green LED ON
indicates that the received signal has a reserve greater
than 30% compared to the output switching value.
Power on indicator (emitter only): The green LED
indicates that the sensor is operating and the laser is
active.
Potentiometer (receiver only)
The potentiometer can be used to adjust sensitivity.
Caution! Do not turn the potentiometer beyond the
mechanical stop at 270°.

Installation
There are three ways to attach the sensor:
1. Using two screws (M4) and washers through the
housing mounting holes.
2. Using a mounting bracket (available separately).
3. Using special clamps (available separately) and the
dovetail housing profile.
The operating distance is measured from the front surface
of the sensor optics.
The M12 connector can be oriented at four different
ratchet positions of 0°, 90°, 180° or 270°.

Test function
The TEST+ input can be used to inhibit the emitter and
verify that the system is correctly operating.
The receiver output should switch when the test is
activated while the beam is uninterrupted.
The inputs activating voltage range is 10 ... 30 V DC,
whilst respecting the polarity.
Connect the TEST+ input to 0V if not used.
