Ultrasonic Sensors
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.
Depending on the set window limits,
a distance-proportional analogue sig-
nal is output.
Via the push-button, the detect dis-
tance and operating mode can be
adjusted (teach-in). Two LEDs indi-
cate operation and the state of the
output.
Safety Notes
■ Read the operating instructions
prior to start-up.
■ Connection, installation and
adjustment works may only be
carried out by expert personnel.
■ No safety component in
accordance with the EU Machine
Directive.
Proper Use
sks ultrasonic sensors are used for
non-contact detection of objects.
Installation
■ Mount the sensor at the installa-
tion site.
Maximum torque of screws:
0,5 Nm
■ Connect a connection cable to the
M8 device plug.

plug and colour coding of the
microsonic connection cable
Start-Up
■ Connect the power supply.
■ Carry out the adjustment in
accordance with the diagram.
Factory Setting
■ Rising analogue characteristic
curve between the blind zone and
the operating range.

Synchronization
If several sensors are mounted close
to another, they should be synchroni-
zed with each other. This is done by
an externally provided synchronisati-
on signal.
■ Apply a square-wave signal to the
sync-input with pulse width t
i and
repetition rate t p (Fig. 3 and
technical data).
Any amount of sensors may be syn-
chronized with this external synchro-
nisation signal.
A high level on the sync-input will
deactivate the sensor.

Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface.
Notes
■ The sks sensor uses an internal
temperature sensing element to
compensate the temperature de-
pending speed of sound. In the
first 45 seconds after power on
every time the sks tests this tem-
perature compensation and after-
wards sets the analogue output
according to the compensated dis-
tance value.
■ The temperature compensation
automaticly adjusts to the actual
mounting conditions if the sensor
outputs current of 11 to 13 mA or
voltage of 4.4 to 5.6 V for at least
30 minutes after switching on
power supply.
■ The sks sensor has a blind zone,
within which distance measure-
ments are not possible.
■ In the normal operating mode, an il-
luminated yellow LED signals that the
object is within the adjusted win-
dow limits.
■ If the push-button is not pressed
for 30 seconds during the teach-in
setting, the settings made hitherto
are deleted.
■ The sensor can be reset to its fac-
tory setting (s. »Further settings«).
