Background suppression sensor RL28-8-H-2000-IR/105/110

Release date: 2018-03-26 09:39 Date of issue: 2018-03-26 419613_eng.xml
Intended use:
The transmitter and receiver are located in the same housing for direct detection sensors with background masking. Marking of
objects outside the detection range is achieved by arranging the angle between the transmitter and receiver (2 receiver ele-
ments).
Objects are detected independently of their surface structures, brightness and colour, as well as the brightness of the back-
ground.
Mounting instructions:
The sensors can be fastened directly with fixing screws or with a support bracket (not included with delivery).
The surface underneath must be flat to prevent the housing from moving when it is tightened into position. We recommend se-
curing the nut and screw in place with spring washers to prevent the sensor from going out of adjustment.
Adjustment:
After the operating voltage is applied, the LED is lit green.
Align the sensor to the background. If the yellow LED is lit, the detection range should be reduced with the detection range ad-
juster until the yellow LED goes out.
Object direction:
Place the object to be detected at the desired maximum detection range and align the light spot to it. If the object is detected,
the yellow LED lights up.
If it does not light up, the detection range must be adjusted on the potentiometer until it lights up when an object is detected.
Cleaning:
We recommend cleaning the optical surface and checking the screwed connection and other connections at regular intervals.
