Safety Information for SR-500 Series
General cautions
• Take substantial safety measures to avoid any damage in the unlikely event
of a problem occurring.
• Do not modify the SR-500 Series, or use it in any way other than described
in the specifications.
• When the SR-500 Series is used in combination with other devices, functions and performance may be degraded, depending on the operating
conditions and surrounding environment.
• Parts of this manual may not be used or duplicated without express permission.
• The contents of his manual are subject to change without notice.
Operating Precautions
•
Do not use a voltage other than 5VDC with the SR-500
Series. Doing so may lead to damage on the unit.
When using the dedicated communication units (NX-50
Series, N-R2/R4/UB/L1, or DV-90 Series), use a power
supply within the appropriate range for each unit.
• Be sure to turn the power off to devices attached to the
SR-500 Series when you plug or unplug the cables. Failure
to do so may cause damage to the SR-500 Series.
• Do not disassemble or modify the SR-500 Series. Doing so
may lead to damage on the unit.
• Keep the cables away from high-tension cables or power
sources. Otherwise, noise could cause malfunctions or
accidents.
• The SR-500 Series is a
precision instrument. Do
not apply shock to the
instrument or drop it. Be
especially careful when
transporting or installin g the
unit.
Caution
• Do not hold the SR-500
Series by its cable. The
units may become
damaged if they strike
each other.
Important notes
When planning to use the SR-500 Series in situations or environments
described below, use it with ample margins in terms of ratings and functions,
and take appropriate failsafes and other safety measures.
• Usage in situations or environments other than those described in this
manual.
• Usage with nuclear power controls, railroad installations, aircraft installations, automotive equipment, combustion equipment, medical equipment,
recreational equipment, or safety devices.
• Applications that are determined to have a large influence on life or property, and additional safety measures are desired.
Safety precautions on laser product
The 2D Code Reader SR-500 Series uses a visible semiconductor laser as a
target pointer for adjusting the reading position.
This laser has a wavelength of 655nm and is classified as a Class 1 laser
under IEC standards (IEC60825-1: "Safety of Laser Products").
• Do not allow water, oil, dust, or other foreign substances to
stick to the scanner. This may cause read errors. Use a
soft, dry cloth to wipe any substances from the scanner.
(Do not use a cloth dipped in alcohol or other cleaning
substance.)

The optimum angle for the
SR-500 Series is 20° from
the line perpendicular to
the back of the unit.
Reading distance
20°
Connect using a cable that is
4.8m or less in length.
• Do not use a reverse connection to the power supply.
Doing so may lead to damage on the unit.
• Use a stable power supply that is 5VDC+5%, -10%. Using
a power supply that exceeds this range may lead to
damage on the unit.
• Use an NEC Class 2 output power supply when operating
under UL standards.
Timing and preset input wiring
The timing input is used on the SR-500 Series to start reading 2D codes or barcodes.
The preset input is used on the SR-500 Series to register data from the 2D
codes or barcodes.
• The timing and preset inputs are both non-voltage inputs.
Installing the SR-500 Series
Adjust to the following installation angle and distance when installing the SR500 Series.
Adjusting the installation angle
The scanner for the SR-500 Series should be tilted 20° compared to the 2D
code or barcode surface to read. Installing at this angle provides the optimal
reading stability.
Adjusting the installation distance
1 Press the [TUNE] switch on the SR-500 Series to emit the laser pointer, and
adjust the installation distance.
The laser pointer emits as shown in the diagrams below.
For the SR-500
The point where the laser pointers intersect
is the optimum reading distance.
Adjust the laser pointer intersection so that
it lies directly in the middle of the 2D code
and barcode.
29mm
OK/NG/ERROR/BUSY output wiring
• OK output is used when the reading is successful, checked against the preset data, and determined to be okay.
• NG output is used when the reading is checked against the preset data
and determined to be NG (not good).
• ERROR output is used when the reading has failed.
• BUSY output is used as the waiting signal when a timing input has not been
received by the SR-500 Series, or it is used as the preset data registration
completion signal or the control signal for the external light.
Each signal is output in the format of NPN open collector.

2 Use the [TEST] switch and check the reading stability in both reading rate
measurement mode (press for 1 second) and reading position measurement
mode (press for 3 seconds). Fine tune the reading distance and angle for the 2D
codes and barcodes that you plan to use.
When using workpieces such as directing marking on boards

where there is low contrast between the code and the
background, increase the installation angle (larger than 20°)
to stabilize the reading.

may occur.
• The distances or angles that can be used for reading may
vary with the size or print quality of the 2D code or barcode
being read.
Use test mode to actually read the 2D code or barcode
during installation.
Mounting SR-500 Series
There are two methods for installation: using the mounting bracket, and not
using the mounting bracket.
Installing with the mounting bracket
2 Secure the mounting bracket in place.
• Purchase installation screws (M4) separately. (Use
Note
screws that are 10mm or longer.)
• Be sure to use the insulating spacers on the side
closest to the mounting brackets to suppress noise.

Secure the mounting position of the SR-500 series with three screws (M3).
The SR-500 Series can be installed in the directions shown in the diagrams
below. Choose a mounting direction that best fits your application.
Purchase installation screws separately. The type of
screw required depends on factors such as the thickness
of the board where the SR-500 Series is mounted.
