Structure and function
4.2 Function
The UM18-2 Pro is an ultrasonic sensor for performing non-contact
distance measurement or detection of objects, animals, and persons.
The circuit variations have the following operation modes: Distance to
Object (DtO), Window (Wnd), and Object between Sensor and Background
(ObSB). The measured distance value is transferred cyclically over an
IO-Link interface.
Depending on the model, the analog versions output a voltage or current
value corresponding to the measured distance value and the scaling on
the customer side.

NOTE!
Distance measurement is not possible within the blind
zone of the ultrasonic sensor. → See Page 42,
Chapter 11.2.
NOTE!
→ For mounting accessories, see Internet
"www.sick.com/um18", Accessories.
1. Select the mounting location for the ultrasonic sensor according to
the requirement. Keep in mind the specications in the technical
data, such as the detection range. → For dimensions, see Page 41,
Chapter 11.1. → For detection range, see Page 46, Chapter 11.9.
2. Insert the ultrasonic sensor through the hole in the mounting bracket.
3. Tighten mounting nuts using a maximum torque of 15 Nm.
5.2 Smooth object surfaces
For smooth object surfaces, we recommend an angle of 90° ± 3° between
the sensor axis and the object surface. A larger angle is possible for rough
surfaces.

Mounting
5.3 Mounting multiple ultrasonic sensors
5.3.1 Minimum mounting distances
If you would like to operate multiple ultrasonic sensors and the mount-
ing distance is lower than the value specied in Table 3 (page 16), we
recommend using synchronization or multiplex mode. Synchronization or
multiplex mode avoids mutual interference between the sensors.
→ For synchronization mode, see Page 16, Chapter 5.3.2.
→ For multiplex mode, see Page 17, Chapter 5.3.3.

5.3.2 Synchronizationmode
NOTE!!
The synchronization mode is not available in IO-Link
mode.
Descriptionofsynchronizationmode Synchronization mode begins automatically as soon as the sensors are
interconnected via PIN 5 (MF).
The sensors measure simultaneously in synchronization mode.
This operating mode prevents unwanted mutual interference since
measurements from dierent times are not incorrectly compared with one
another. The sensors can therefore be mounted without taking into account
mounting distances.
The acoustic pulses of a sensor deected by an object can still be analyzed
by neighboring sensors. This makes it possible to implement more reliable
and simultaneous monitoring of large areas with synchronization mode, but
without position detection of the recorded objects.
The detection zone is enlarged to a size which covers all synchronized
sensors. A maximum of 20 sensors of type UM18-2 Pro can be connected,
and they can also be combined with synchronizable SICK ultrasonic
sensors from other product families.
The response time of the overall system is determined by the sensor with
the highest response time.

5.3.3 Multiplex mode
Mounting
PIN 5
Fig. 4: Synchronization mode
NOTE!!
The multipex mode is not available in IO-Link mode.
Description of multiplex mode To change to multiplex mode, sensors must be interconnected via
PIN 5 (MF) and dierent addresses must be assigned to them using the
Connect+ software.
In multiplex mode, all sensors measure in alternation in a dened
sequence. This operating mode prevents unwanted mutual interference
since measurements from dierent times cannot be incorrectly compared
with one another. The sensors can therefore be mounted without taking
into account mounting distances.
Thanks to alternating measurement, the monitoring of large areas is
possible with additional position detection of recorded objects.
The detection zone is enlarged to a size which covers all connected
sensors. A maximum of 20 sensors of type UM18-2 Pro can be connected,
and they can also be combined with synchronizable SICK ultrasonic
sensors from other product families.
Since measurement by the sensors is done in alternation, the response
time of the total system is increased in accordance with the “overall
response time” formula.
NOTE!
For multiplex mode, you must assign a unique address to
the sensors. The "Connect + Adapter" and the associated
software is required for this (order no. 6037782)

Electrical connection
All electrical connections of the ultrasonic sensor are congured as M12
round connectors.
The IP 67 protection class is only achieved using screwed plug connectors
or cover caps.
By using suitable cable entries and wiring, you can avoid interference
from devices such as switching power supplies, motors, clocked drives,
and contactors.
• Lay cables as far away as possible from cables having a high level of
radiated emission. If needed, employ additional measures such as
shielding plates.
• Do not lay cables parallel to other cables, particularly devices with a high
level of radiated emission, such as frequency converters.
• Do not lay cables parallel to energy cables.
6.3 Connecting the ultrasonic sensor electrically
1. Ensure that there is no voltage.
2. Connect the ultrasonic sensor according to the connection diagram.

7.4 Temperature compensation
The UM18-2 Pro sensors feature internal temperature compensation. Due
to the sensor heating up, the temperature compensation function will reach
its optimal working point after approximately one minute.
Temperature compensation is calibrated for standard mounting condi-
tions, using an aluminum mounting bracket and mounting screws, at the
factory. It is automatically and optimally calibrated to the individual installation situation when the sensor is cold and the switching output has been
deactivated for approx. 30 min., or the analog output has been outputting
a constant value of between 11 and 13 mA or 4.4. and 5.6 V for approx.
30 min. If the measured value changes over the course of these 30 min.,
the calibration process running in the background is aborted. The standard
parameters or the parameters last calibrated are retained. This function is
very helpful when the installation situation diers greatly from the standard
mounting conditions (e.g. in the case of thermally insulated mounting) and
a very high level of accuracy is required.
Temperature compensation can be switched o via
“Connect+ Adapter,” not temperature-compensated: 0.17 %/K

7.5 Measuredvaluelter
Filter settings The following lter settings can be selected for the UM18-2 Pro ultrasonic
sensors using "Connect+ Adapter":
Filter F00 provides an unltered output for the measured values.
This mode is not permitted, as undesired EMC faults could result.
Decreasing distance values are checked by lters F01 and F02 only for
plausibility and then output without any further conditions. After checking
for plausibility, increasing distance values are tracked only if they do not
exceed a specied tolerance range for the rate of increase. If the deviations
are too great, they are classied as interference variables by the software
and bridged for an adjustable holding time according to lter strength P.
Filter F01 provides interference protection against individual pulses such
as EMC spikes in connection with protection against measured value jumps
that are away from the sensor. The lter is suitable for bridging signal
jumps.
Filter F02 provides interference protection against individual pulses
such as EMC spikes in connection with protection against very brief
measured value jumps away from the sensor. The lter reacts very quickly
to measured values near the sensor and provides a smoothed output of
measured values based on approximately arithmetic averaging. This lter
is therefore especially suitable for smoothing uctuating measured values.
Smoothing according to the lter strength P.
Filter F03 and F04 do not include a plausibility check. Thereby they waive
an interference protection against single interfering impulses and thus
resulting measurement value jumps with direction to smaller (F03) or larger
(F04) distance values. In return they react very quickly to measurement
value changes in the preferred distance level (F03: near sensor; F04: away
from sensor) and provide a smoothed output of measurement values in
this distance level, according to lter strength P.
In the opposite direction an adjustable holding time as well as an averaging
take eect, both operating according to lter strength P.
With lter F03 background reections of unexpected objects are faded out.
With lter F04 foreground reections of unexpected objects (e.g. stirring
tools) are faded out.

again.
Teach failed, for example, due to interfering
reections or mounting distances that are
too small when using multiple sensors.
Analog output only: Taught-in distance
between the scaling limits is below 1 mm.
• Check the sensor detection zone and keep
