4.3 Operating principle
Ultrasonic sensors are designed for the non-contact and wear-free detection of a variety of tar-
gets by means of sound waves. It does not matter here whether the target is transparent or
non-transparent, metallic or non-metallic, solid, liquid or in powder form. Environmental condi-
tions such as spray, dust or rain also hardly affect the functioning of the sensors.
Ultrasonic sensors emit one or several ultrasonic pulses that are propagated in the air at the
speed of sound. A part of the ultrasonic wave is reflected by the object. The sensor measures
the total time of flight from the sensor to the object and back to the sensor. The distance to the
object is then calculated with the following formula:
D=c×t/2
D Distance from the sensor to the object in m
c Speed of sound in air in m/s
t Time of flight for the ultrasonic pulse in s
To improve accuracy, the ultrasonic sensor forms the mean value from the measurement of
several sound pulses before outputting a new value. The ultrasonic velocity depends on the
composition and the temperature of the gas in which the sound is propagated. In most ultra-
sound applications, the composition of the gas is stable whereas the temperature may often
fluctuate.
The speed of sound in air varies with the temperature according to the following approxima-
tion formula:
cair= 20×√(273+T)
cair Speed of sound in air in m/s
T Temperature in °C
The speed of sound at an air temperature of 20 °C is approximately 344 m/s
The following formula applies to sensors with integrated temperature compensation:
cair= (331.5×0.596+T)
Fluctuations in air temperature affect the speed of sound, which in turn has an effect on the
total time for the echo measured by the sensor. An increase in air temperature shifts both
measuring range limits closer to the sensor and the time of flight of the echo is shorter. A drop
in air temperature shifts both measuring range limits away from the sensor and the time of
flight of the echo is longer. This shift is approximately 3.5% of the limit distance with a
temperature change of 20°C.
Good ultrasonic reflectors are metals, glass, stone, wood with smooth and hard surfaces, as well
as liquids that are aligned appropriately to the sensor. Cloth, sand or grains absorb some of the
sonic energy. Foams and skins are particularly poor reflectors.

Functions and operating modes
10 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
4.4 Functions and operating modes
The ultrasonic sensors are provided with two switching outputs that can be set independently
of each other. Output 1 can be used as a switching output, and output 2 can either be used as a
switching output, current output (4…20mA/0…20mA) or voltage output (0…10V/0…5V/1…
6V ). The start and end point of the measuring range can be set for the outputs. The measuring
range must be within the detection range. The sensors can be run in normal operation as a dif-
fuse mode or retroreflective sensor. The user can set an individual switching point as well as a
window or hysteresis function.
Other operating modes (opposed, multiplex, synchronization or enable mode) can be paramet-
erized via IO-Link.
4.4.1 Setting options
The devices feature the following setting options:
nSetting by manual bridging (shorting)
nSetting with connected teach adapter (accessories to be ordered separately)
nSetting via the pushbuttons
nSetting via IO-Link
4.4.2 Diffuse mode sensor
The diffuse mode is the standard operating mode of most ultrasonic sensors The sensor detects
the required object via the echo of the ultrasonic waves. The distance to an object is determ-
ined from the time of flight. Any additional wiring or accessories are not required.
When using diffuse mode sensors, a switching point or switch window is defined. The switch
window is used for window or hysteresis functions.
Diffuse mode sensor with NC function
When used as a diffuse mode sensor with an NC function, a switching point is taught in for a
switch output. The output behaves as follows:

Hysteresis function
When using the hysteresis function, a switch window is taught in that is defined by two switch-
ing points. The switching outputs have the following behavior as outputs:
If an object is moved away from the sensor, the switching output is switched on for as long as
the object is located between the beginning of the detection range and switching point 2. If
the object passes switching point 2, the switching output is switched off. If an object is moved
towards the sensor, the switching output is switched off for as long as the object is located
between the beginning of the detection range and switching point 1. If the object passes
switching point 1, the switching output is switched on.

4.4.3 Retroreflective mode
When used as a retroreflective sensor, the sensor detects the echo of the ultrasonic waves of
the taught reflector. The reflector can be any object with a surface that is as smooth as possible.
The sensor generates a short switching window around the position of the reflector and de-
tects the echo. The sensor switches if the echo is blocked or deflected by another object.
This operating mode is normally more reliable than the diffuse mode and is particularly suitable
for objects that are difficult to detect and in difficult ambient conditions.
Any additional wiring or accessories are not required.
Synchronization with other sensors is not possible in this operating mode.
When used as a retroreflective sensor switching output2 is switched on. The behavior of
switching output 1 is inverted in relation to switching output 2.

4.4.4 IO-Link mode
Other operating modes which cannot be set via pushbuttons or the teach-in input can be set
via IO-Link. This applies to the following operating modes:
nMultiplex mode
nSynchronization mode
nEnable mode
nOpposed mode
IO-Link is only required for setting up the device. The IODD of the device must be incorporated
in an FDT frame (e.g. Pactware). The operating modes can be set via FDT/ IODD.
The operating modes cannot be combined with each other. The appropriate bit in the process
output data is used for synchronization or multiplex operation via the IO-Link process data. In
this case, wiring the sensors together is unnecessary. The time sequence is controlled by the
IO-Link master.

Product Description
Functions and operating modes
14 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
Multiplex mode
Multiplex mode is used to prevent the mutual feedback of sensors operating at the same ultra-
sonic frequency. Up to ten devices can be operated in sequence. Each sensor operates at a
fixed time while all other sensors remain in wait mode. Multiplex mode must be set once for all
sensors via IO-Link. Each sensor is assigned a unique address between 1 and 10. The device
with the highest number set operates automatically as the master clock. This requires the
sensors to be interconnected.
NOTE
Multiplex mode is only possible with devices of the same type.
All connected sensors must have the same power and range in multiplex mode. In
multiplex mode, only connect sensors with the same ID no. The ID no. is marked on
each device.
Output 1 on the master device is not available in this mode. A teach-in operation is not possible
in this mode during operation. No other accessories are required for operation.
Synchronization mode
The mutual feedback of sensors operating at the same ultrasonic frequency can be prevented
in synchronization mode. Feedback is prevented since all sensors send and receive at the same
time. Any number of sensors can be operated in synchronization mode. The devices do not
have to be addressed. One of the sensors deployed is defined by the wiring as the master clock.
NOTE
Synchronization mode is only possible with devices of the same type.
All connected sensors must have the same power and range in synchronization
mode. In synchronization mode, only connect sensors with the same ID no. The ID
no. is marked on the device.
Output 1 on the master device is not available in this mode. A teach-in operation is not possible
in this mode during operation. No other accessories are required for operation.
Enable mode
Enable mode enables the targeted activation and deactivation of the sonic transducer of indi-
vidual sensors. In enable mode, each sensor is only active if a signal to UB is issued at pin 5. Syn-
chronization or multiplexing can be implemented in enable mode. Sensors with a different
power and range can be used at the same time in enable mode. An ultrasonic sensor is not
used as the master clock. The signal must be switched externally to each device via a PLC. The
sensors do not have to be interconnected. Inactive sensors output the valid values that were
last measured. The outputs can be used in the normal way. IO-Link operation is not possible in
this mode.

V2.0 | 2021/06 15
Opposed mode
Two sensors with the same power and range are required for opposed mode. One sensor oper-
ates in this mode as the emitter and the other sensor as the receiver. The devices are positioned
and aligned opposite each other. This makes it possible to double the effective range of the
sensors. The opposed mode is the most reliable operating mode. All objects that interrupt the
sonic wave are detected. Whether a device is to operate as an emitter or receiver is determined
by the wiring.
NOTE
Opposed mode is only possible with devices of the same type.
All connected sensors in opposed mode must have the same power and range. In
opposed mode, only connect sensors with the same ID no. The ID no. is marked on
each device.
The outputs of the sensor connected as the emitter are not available. The receiver only offers
one switching output on pin 4. IO-Link operation is not possible.

5 Installing
NOTE
When using more than one ultrasonic sensor in an application:
Avoid the overlapping of sonic cones.
This can occur if two sensors are mounted less than 200mm (RU40…), 450mm
(RU130…), 1000mm (RU300…) or 2000mm (RU600…) apart.
If this distance is undershot, synchronize the sensors using IO-Link.
The sensors can be mounted in any direction. The maximum tightening torque for fastening
the sensors is 20 Nm.
Clean the mounting surface and its surroundings.
When using a mounting aid: Fasten the sensor in the mounting aid.
Install the sensor or mounting aid at the intended position.
Ensure that the rear plug connector is accessible.
Mount the sensor so that the blind zone is clear of any relevant objects (see wave
patterns or technical data).
