1. Safety precautions
· Use supply voltage and interfaces indicated in the scanner specifications.
· In connection/disconnection of cables, the scanner power must be switched off.
· Do not use scanners in locations close to powerful light sources.
· To obtain stable results, wait about 20 minutes after scanner activation to achieve
uniform scanner warm-up.
· Scanners must be grounded.
2. CE сompliance
Laser scanners have been developed for use in industry and meet the requirements
of the following Directives:
· EU directive 2014/30/EU. Electromagnetic compatibility (EMC).
· EU directive 2011/65/EU, “RoHS“ category 9.
3. Laser safety
Scanners belong to 2M laser safety class according to IEC/EN 60825-1:2014.
Scanners make use of an c.w. 660 nm or 405 nm or 450 nm or 808 nm wavelength
semiconductor laser. Maximum output power is 10 mW. The following warning label is
placed on the scanner housing:
The following safety measures should be taken while operating the scanners:
· Do not target laser beam to humans.
· Do not disassemble the scanner.
· Avoid staring into the laser beam.
4. General information
Laser scanners are designed for non-contact measuring and checking of surface
profile, position, displacement, dimensions, sorting and sensing of technological objects,
3D models construction.
5. Structure and operating principle
Operation of the scanners is based on the principle of optical triangulation (see
Figure below).
Radiation of a semiconductor laser is formed by a lens in a line and projected to an
object. Radiation scattered from the object is collected by the lens and directed to a two-
dimensional CMOS image sensor. The image of object outline thus formed is analyzed by a
FPGA and signal processor, which calculates the distance to the object (Z-coordinate) for
each point of the set along the laser line on the object (X-coordinate). Scanners are
characterized by the following parameters:
· smrZ - the beginning of the range for the Z-coordinate,
· MR - the measuring range for the Z-coordinate,
· Xsmr - the measuring range for the X-coordinate at the beginning of Z,
· Xemr - the measuring range for the X-coordinate at the end of Z.

Laser Scanners
RF627, RF627Smart [Revision 2.1.2] 20.09.2021
6. Configurations, operating modes, options
The following configurations are available:
· red laser scanners, 660 nm;
· blue laser scanners (BLUE version), 405 or 450 nm;
· infrared laser scanners (IR version), 808 nm.
We use different lasers due to a wide range of applications. For example, the use of
blue lasers instead of red ones is optimal for the control of shiny materials, high-
temperature objects and organic materials.
The use of scanners with lasers of different wavelengths in one measurement
system makes it possible to avoid the scanners mutual influence and greatly simplifies the
system construction. An example of system implementation: https://youtu.be/9evAIXqrPas
Scanners can be equipped with a built-in heater for operation under low-
temperature conditions. Scanners can be equipped with the air (water) cooling system and
the air-knife system for windows.
There are two operating modes in the full working range: Basic mode with the
frequency of 485 Hz (profiles/second) and DS mode with the frequency of 938 Hz.
In addition, you can use the ROI function, which makes it possible to increase the
working frequency of the scanner in the limited working range up to 5096 Hz in Basic mode
and up to 6800 Hz in DS mode.
The Smart version of the scanner (RF627Smart) makes it possible to measure
geometric parameters of the object profile in real time directly in the scanner without
connecting to a computer. Analysis, calculations, measurements, tolerance control are
carried out according to the algorithm created by the user. To build an algorithm, a simple
and intuitive tool is provided - a computation graph. The graph is formed from a library of
ready-made blocks. Various combinations of blocks and connections between them allow
the user to create an almost unlimited number of measuring functions, as well as to process
profiles of any complexity. Measurement results can be transmitted via various protocols
(Ethernet/IP, Modbus TCP, UDP), as well as to the logic outputs of the scanner in order to
control the actuators and notify about product suitability.
NOTE: By purchasing the RF627 scanner, you get the opportunity to use all the
functions of the RF627Smart scanner for 100 hours. The trial period can be extended upon
request. To use all functions of the RF627Smart scanner for an unlimited time, you must
purchase a license (it is possible to purchase a license for certain functions). For more
details, refer to par. 23.3.

The housing of the scanner is made of anodized aluminum. The front panel of the
housing has two windows: the output window and the window for receiving radiation
reflected from the object under control. Overall and mounting dimensions of the scanners
are shown in the Figures below. The housing has fastening holes for installing the scanner
on the equipment. The sensors, shown in Figure 3, are equipped with an adjustable support
that allows you to implement three options for mounting the scanner.
The scanner has two connectors, Reset button and LED indicators.

Note: Overall dimensions of the sensors with the AK, EW and AC options are given in Annex 3. Detailed
documentation (2D and 3D) is available for download on RIFTEK's official website.
9. Overall demands for mounting
The scanner should be positioned so that the object under control has to be placed
within the working range of the scanner. In addition, no foreign objects should be allowed to
stay on the path of the incident and reflected laser radiation.
Where the objects to be controlled have intricate shapes and textures, the incidence
of mirror component of the reflected radiation to the receiving window should be minimized.
ATTENTION!
The scanner must be grounded. Static electricity may cause the failure of electronic components.
10. Connection
Scanners come with two cables:
1) Ethernet cable;
2) Power cable with synchronization lines and outputs.
ATTENTION!
Below is a description of the cables that come with standard configuration scanners.
Documentation on the cables is always included in the delivery package.
10.1. Designation of connector contacts
The scanner is equipped with two connectors:
1. Ethernet connector.
2. Multi-connector.
View from the side of connector contacts is shown below:
