Curves/Diagrams
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 the structure and colour of the surface.
The special design of the sensors makes it possible to install them between two rollers in the roller back-up conveyor systems
under the material that is being moved.This allows for installation that saves space and prevents mechanical damage of the
sensor caused by material being conveyed.
Mounting instructions:
The sensors can be directly fastened in place with the pass-through bore holes or can be attached with a support bracket or a
clamp (the last two are not included in 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.
For versions SBL-8-H-SL, -V, -Z
As many as 25 sensors can be cascaded with the aid of just one power supply. A solenoid valve is energised if the correspon-
ding sensor itself or its predecessor in the cascade does not see any object.
It is also possible to energise the valves of all sensors included in the cascade with block movement (V
positive supply voltage (+UB) on the input V
Adjustment:
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 detection:
Position the object to be detected in the path of the beam. If the object is detected, the yellow LED lights up.
If it does not light up, the detection range must be further adjusted on the potentiometer until it lights up when an object is de-
tected.
Version SBL-8-H-SL-V-Z only:
The two adjusting mechanisms on the front side of the sensor can be used separately for timer functions for the switching on
or switching off process.
This results in a delay defined by the adjuster between the change of state (object detected -> object not detected or vice-versa)
and the switching process. The duration of the delay can be set for up to 2 seconds.
Cleaning:
We recommend cleaning the optical surface and checking all connections at regular intervals.
Note:
Use a screwdriver to adjust the sensing range. We strongly recommend to use the screwdriver given in the accessories section.
