2 Safety information
2.1 Intended use
The Dx1000 distance sensor is an opto-electronic measuring device and is used for
optical, non-contact distance measurement of objects.
The distance sensor is used for the detection of distances between the distance
sensor and a measuring object. The measuring object can be a natural object (DT1000
product variant) or a suitable (retro-reflective) reflector (DL1000 product variant). The
required optical properties of the measuring object are specified in the technical data
section of this document.
SICK AG assumes no liability for losses or damage arising from the use of the product,
either directly or indirectly. This applies in particular to use of the product that does not
conform to its intended purpose and is not described in this documentation.

2.7 Operational safety and particular hazards
Please observe the safety notes and the warnings listed here and in other chapters
of this product documentation to reduce the possibility of risks to health and avoid
dangerous situations.
The device is equipped with two laser sources:
•Measurement laser (not visible to the human eye)
•Alignment laser (visible to the human eye)
Both lasers are classified as class 1 lasers based on the IEC 60825-1:2014
standard. The requirements for qualifying as a class 1 laser are met even if both
lasers are operated simultaneously. Complies with 21 CFR 1040.10 and 1040.11
except for tolerances according to “Laser Notice No.50” dated June 24, 2007.
CAUTION
Optical radiation: Laser class 1
The accessible radiation does not pose a danger when viewed directly for up to 100
seconds. It may pose a danger to the eyes and skin in the event of incorrect use.
■Do not open the housing. Opening the housing may increase the level of risk.
■Current national regulations regarding laser protection must be observed.
CAUTION
Hot surface!
The device is equipped with a heater. The viewing window can become hot when the
heater is operating.
■When performing work directly on the device (e.g. cleaning, disassembly), switch
off the device if necessary and allow it to cool down.
WARNING
Electrical voltage!
Electrical voltage can cause severe injury or death.
■Work on electrical systems must only be performed by qualified electricians.
■The power supply must be disconnected when attaching and detaching electrical
connections.
■The product must only be connected to a voltage supply as set out in the require‐
ments in the operating instructions.
■National and regional regulations must be complied with.
■Safety requirements relating to work on electrical systems must be complied with.
WARNING
Risk of injury and damage caused by potential equalization currents!
Improper grounding can lead to dangerous equipotential bonding currents, which may
in turn lead to dangerous voltages on metallic surfaces, such as the housing. Electrical
voltage can cause severe injury or death.
■Work on electrical systems must only be performed by qualified electricians.
■Follow the notes in the operating instructions.
■Install the grounding for the product and the system in accordance with national
and regional regulations.

3 Product description
3.1 Scope of delivery
Included in scope of delivery:
■Distance sensor
■Protective caps for connections (on the device)
■Printed Safety Notes, multilingual (brief information and general safety notes)
With special variants, where optional extras have been ordered, or owing to the latest
technical changes, the actual scope of delivery may vary from the features and illustra‐
tions shown here.
3.2 Product characteristics
The distance sensor consists of the optics, a sender/receiver unit and an evaluation
unit.
The device emits invisible, infrared laser beam pulses. The receiver receives the light
reflected from a measuring object (=echo). The evaluation electronics determines the
distance between the sensor and the measuring object using time-of-flight measure‐
ment.
The device supports two measuring modes.
•Axial object tracking: Measuring object moves along the laser beam.
•Lateral entry of the object: Measuring object moves perpendicular to the laser
beam.
Parameter presettings simplify device configuration for the respective measuring mode.
The achievement of configurable switching limits for the distance values, the speed of
the measuring object and the signal level can be monitored using digital outputs. The
device also offers a wide range of options for transmitting measurement and device
data to a connected controller using the communication interfaces. The analog output
converts the distance value into a 4 mA to 20 mA current output signal proportional to
the distance.
A visible alignment laser facilitates alignment of the device with the measuring object.
The measurement technology is designed for indoor and outdoor applications. For
such applications, the device must be protected from environmental factors, "Mounting
instructions", page 50. The protective housing, available as an option, can be used for
this purpose.
Measured distance values can be visualized and parameter settings can be made
using the graphical touch display. Alternatively, the device can be parameterized via
the thethe EtherNet/IP interface, the SOPAS ET user interface (PC, via Ethernet), the
RS-422interface, or via the Ethernet interface.

3.6 Measured value technology
After application of the supply voltage and initialization, the device is ready for meas‐
urement.
The quality of the measured values in relation to noise and reliability can be optimized
in line with the given application. The following parameters are available here.

Measurement cycle time
Increasing the measurement cycle time causes a rise in sensor detectability. A meas‐
ured value can thus be created from very low signal strengths.
In product variant DT1000, the scalability of the range results from this: the longer
the set measurement cycle time, the larger the range of the sensor, see figure 31,
page 125.
For more information on the measurement cycle time, see "Defining the measurement
cycle time", page 75.

Rain and snow filter
The measurement certainty with precipitation can be increased using the connectible
rain and snow filter.
For more information on the rain and snow filter, see "Configuring the rain and snow
filter", page 76.
Distance averaging filter
The distance averaging filter carries out a moving averaging method of the distance
value.

For more information on the distance averaging filter, see "Configuring the distance
averaging filter", page 77.
Fog filter
The measurement certainty with fog can be increased using the connectible fog filter,
"Activating/deactivating the fog filter", page 77.
Kalman filter
The Kalman filter filters the distance and speed value based on a mathematical status
model.
For more information about the Kalman filter: see "Activating/deactivating the Kalman
filter", page 78.see "Activating/deactivating the Kalman filter", page 78.
Speed filter
The speed filter carries out a moving averaging method of the speed value.
For more information about the speed filter: see "Configuring the speed filter",
page 78.see "Configuring the speed filter", page 78.
3.7 Interfaces
3.7.1 Signal inputs/outputs
Table 5: Overview of input/output signals
Signal Type Designation
1 Digital input/Digital output (switchable) In1/Q1
2 Analog output/Digital output (switchable) QA/Q2
3.7.2 SSI (synchronous serial interface)
The SSI interface makes possible serial data transmission of the distance value or of
the distance value combined with the status information. Clock and data are transfer‐
red over the interface. The data is transferred upon request from the control system.
For this purpose, the connected control unit applies a pulse sequence to the receiving
input of the measuring device. At each positive pulse edge, a data bit is pushed
onto the measuring device’s transmission line. This starts with the highest-value bit.
There is a pause of at least 30 µs between two pulse sequences. The cycle time and
transmission rate can be adjusted in wide limits on the control side. The bit pulse is
between 70 kHz and 500 kHz and is dependent on the length of cable, see "Wiring
instructions", page 60.

Depending on the set SSI coding ("Defining SSI coding", page 103), the SSI telegram is structured according to the
following tables. For more information on the SSI status bits, see table 48, page 120.

3.7.3 RS-422 interface
The serial interface makes it possible to read out the measured values and other
defined operating data and transmit parameter data to the device. All data is transmit‐
ted as ASCII characters. The syntax of the communication protocol corresponds to the
specifications of the SICK SOPAS CoLa A protocol, see "Commands", page 22 .
