Mounting device
1.  Perform one of the following steps:
•  Mount the device on a bracket supplied by the 
customer using M5 screws. To do this, either 
use the threaded mounting holes in the hous-
ing in pairs at the front or below or use the two 
M5 sliding nuts in the lateral slots. Mounting 
bracket no. 2042902 can be attached at the 
bottom or on the sliding nuts. Screw the screws 
no more than 5 mm into the blind tapped 
holes. - Dimensional drawings, see “Setup 
and function” on page 4.
•  Attach the SICK bracket that has been or-
dered separately (e.g., mounting bracket no. 
2042902) to the sensor using the two sliding 
blocks. Refer to the “Mounting” chapter of the 
 Technical Information “Image-Based Code 
Reader” Lector620.
Aligning the device plus reading window with 
the code
Remember to consider the shape and alignment of 
the eld of view in front of the device.
Fig. 1:  Example for eld of view and reading eld, size 
elongation depends on device
1.  Working distance
2.  Field of view (area at a certain working distance)
3.  Reading eld (depth of eld)
Taking account of the working distance, depending 
on the resolution
•  Using the Auto-Setup function, the Lector620 
automatically adjusts its focal position to suit the 
working distance from the code.
•  ECO variant: The focal position is set by entering 
the working distance in SOPAS.
Variant-dependent visual and reading eld diagrams 
can be found on the SICK product page in the web:

typical 20°
Fig. 2:  Selection of the skew angle, depending on the 
application
 Tilt the device away from the plane that is per-
pendicular to the surface of the code to avoid as 
many interfering reections as possible. Typically, 
this angle will be between 10° and 20°. In the 
case of codes created on metal, e.g., by dot peen-
ing, an angle of between 0° (bright eld light) and 
45° (dark eld light) may be advisable.
Mounting the CDB connection module
These operating instructions describe the commis-
sioning of the CDB620-001 connection module. For 
more information, see  Operating instructions 
“CDB620-001 connection module operating instruc-
tions” (no. 8012119). Alternatively, you can use the 
CDB650-204 connection module.
 Mount the connection module in the vicinity 
of the device. If you are using the serial data 
interface (RS-232), the maximum recommended 
distance is 5 m.  
Mount the connection module in such a way that 
the Lector620 remains accessible at all times.
Step 2: Electrical installation
•  The electrical installation must only be per-
formed by electrically qualied persons.
•  Standard safety requirements must be met when 
working on electrical systems.
•  Electrical connections between the Lector620 and 
other devices may only be created or disconnected 
when there is no power to the system. Otherwise, 
the Lector620 and devices may be damaged.
•  When using connecting or extension cables with an 
open end, make sure that bare wire ends are not 
touching (risk of short-circuit when the supply volt-
age is switched on). Wires must be appropriately 
insulated from each other.
•  Wire cross-sections in the supply cable from the 
customer's power system must be designed in ac-
cordance with the applicable standards.
•  If the supply voltage for the Lector620 is not 
supplied via the optional CDB620-001 connec-
tion module, the Lector620 must be protected by 
a separate max. 2 A slow-blow fuse in the supply 
circuit.
•  All circuits connected to the Lector620 must be de-
signed as SELV circuits. The power supply or power 
supply unit must satisfy SELV requirements in ac-
cordance with the currently applicable EN 60950-1. 
(SELV = Safety Extra Low Voltage).
 WARNING
Risk of injury and damage caused by electrical 
current!
The Lector620 is designed to be operated in a system 
with professional grounding of all connected devices 
and mounting surfaces to the same ground potential.
Incorrect grounding of the Lector620 can result 
in equipotential bonding currents between the 
Lector620 and other grounded devices in the system. 
This can lead to hazardous voltages being applied to 
the metal housing, cause devices to malfunction or 
sustain irreparable damage, and damage the cable 
shield as a result of a heat increase, causing cables 
to set alight.
 Ensure that the ground potential is the same at all 
grounding points.
 If the cable insulation is damaged, disconnect the 
supply voltage immediately and have the damage 
repaired.
For measures for eliminating hazards, see Chapter 
“Electrical installation”,  in the Technical Informa-
tion “Image-based code readerLector620”.
1.  Connect the communication interface of the 
Lector620 to the PC (Ethernet or USB, depending 
on model).
2.  Supply power to the Lector620 according to the 
type label.

options, see “Overview of all interfaces and connec-
tion options” on page 7.
