sks-15/CF/A
Ultrasonic proximity switch
with one switching output and
IO-Link interface
Product description
The sks sensor offers a non-contact-
measurement of the distance to an
object which must be positioned
within the sensor's detection zone.
The switched output is set in depen-
dance of the adjusted detect distan-
ce.
Via the push-button, the distance
and operating mode can be adjusted
(Teach-in). Two LEDs indicate operati-
on and the state of the switched
output. The output function is chan-
geable from NOC to NCC.
IO-Link
The sks sensor is IO-Link-capable in
accordance with IO-Link specification
V1.1 and supports Smart Sensor Pro-
file like Digital Measuring Sensor.
Safety notes
■Read operating instructions pior to
start-up.
■Connection, installation and ad-
justment works may only be
carried out by expert personnel
■No safety component according to
EU Machinery Directive
Proper use
sks ultrasonic sensors are used for
non-contact detection of objects.
Mounting
■ Mount the sensor at installation
site, Maximum torque: 0.5 Nm
■Connect a connection cable to the
M8 device plug
Start-Up
■Connect the power supply
■Carry out the adjustment in accor-
ding with the diagram
Factory setting
■Operating with one detect point
■Switched output on NOC
■Detect points at operating range
■Filter F01
■Filter strength P00

■Operation with one switching point
The switched output is set if the ob-
ject falls below the set detect point.
■Window mode
The switched output is set if the object
is outside the set window margins.
■Two-way reflective barrier
The switched output is set if the ob-
ject is located between the sensor
and reflector.
Checking operation mode
■In normal mode shortly press the
push-button.
The green LED stops shining for one
second, then it will show the current
operating mode:
1 x flashing = operation with one
switching point
2 x flashing = window mode
3 x flashing = reflective barrier
After a break of three seconds, the
green LED shows the output func-
tion:
1 x flashing = NOC
2 x flashing = NCC
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface.
Notes
■Every time the power supply is swit-
ched on, the sensor detects its actu-
al operating temperature and trans-
mits it to the internal temperature
compensation. The adjusted value is
taken over after 45 seconds.
■If the sensor was switched off for
at least 30 minutes and after po-
wer on the the switched output is
not set for 30 minutes a new ad-
justment of the internal tempera-
ture compensation to the actual
mounting conditions takes place.
■The sks sensor has a blind zone
whithin which distance measure-
ments are not possible.
■In the normal operating mode, an
illuminated yellow LED signals the
switched output is switched
through.
■In the »Set detect point – method A«
Teach-in procedure the actual dis-
tance to the object is taught to the
sensor as the detect point. If the ob-
ject moves towards the sensor (e.g.
with level control) then the taught
distance is the level at which the sen-
sor has to switch the output.
■If the object to be scanned moves
into the detection area from the
side, the »Set detect point +8 % –
method B« Teach-in procedure
should be used. In this way the
switching distance is set 8 %
further than the actual measured
distance to the object. This ensu-
res a reliable switching distance
even if the height of the objects
varies slightly, see fig. 2.
■In the »Two-way reflective barrier«
operating mode, the object has to
be within the range of 0-85 % of
the set distance.

detection zones
for different objects:
The dark grey areas are determined
with a thin round bar (10 mm dia.)
and indicate the typical operating range
of a sensor. In order to obtain the light grey
areas, a plate (100 x 100 mm) is introduced
into the beam spread from the side.
In doing so, the optimum angle between
plate and sensor is always employed.
This therefore indicates the maximum
detection zone of the sensor.
It is not possible to evaluate ultrasonic
reflections outside this area.
