3.3 General safety instructions
nThe device may only be assembled, installed, operated, parameterized and maintained by
professionally-trained personnel.
nThe device may only be used in accordance with applicable national and international regu-
lations, standards and laws.
nNot all objects are detected equally well by the sensor. The detection of the object must be
checked by the user prior to regular operation.
nStrong air movements can disturb the correct function of the sensor and corrupt the meas-
ured values. Avoid air currents between the sensor and the object to be detected.

4 Product Description
The devices are contained in a metal housing with an M18 or M30 male thread. The sonic trans-
ducer surface can be installed flush with the surrounding area.
All devices are provided with a metal M12 male connector for connecting the sensor cable. A
switching distance can be set for object detection, which must be less than or equal to the
maximum detection range, and greater than the minimum switching distance.
The devices can be set via the pushbuttons, teach adapters or by manual bridging, depending
on the design.
The Standard ultrasonic sensors are available both without integrated operating elements and
also with two setting buttons. The devices are provided with two programmable switching out-
puts that can be set as NO or NC contacts. The start and end point of the switch window can be
set for both switching outputs. The switch window must be within the detection range. The
devices can be used as diffuse mode or retroreflective sensors.

Product Description
Operating principle
10 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
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 temper-
ature 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.

4.4 Functions and operating modes
The ultrasonic sensors are provided with two switching outputs that can be set independently
of each other. The sensors can be operated as diffuse mode or retroreflective sensors during
normal operation. The user can set an individual switch point as well as a window or hysteresis
function.
When used in diffuse mode, either a single switch point or a switch window is defined. The
switch window is used for window or hysteresis functions. When used as a retroreflective
sensor, switching output2 is switched on. A small switch window is taught in. The behavior of
switching output 1 is inverted in relation to switching output 2.
When using the hysteresis function, a switching range is taught in that is defined by two switch
points.
4.4.1 Setting options
The devices feature the following three setting options:
nSetting by manual bridging (shorting)
nSetting with connected teach adapter (accessories to be ordered separately)
nSetting via the pushbuttons
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
detects 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.

NOTE
If using more than one ultrasonic sensor in an application: Avoid overlapping of
sonic cones.
Overlapping can occur when two sensors are mounted less than 200 mm RU40…),
450 mm (RU130…), 1000 mm (RU300…) or 2000mm (RU600…) apart.
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
