The DCR40 scanengine is designed as an installation scanner with integrated decoder for all of the most
popular 1D and 2D codes for automatic object recognition.
Areas of application
The DCR40 scanengine is intended especially for the following areas of application:
• In automatic analyzers
• For space-critical code reading tasks
• For installation in a housing or beneath covers
CAUTION
Observe intended use!
The protection of personnel and the device cannot be guaranteed if the device is operated in a
manner not complying with its intended use.
ÄOnly operate the device in accordance with its intended use.
ÄLeuzeelectronicGmbH+Co.KG is not liable for damages caused by improper use.
ÄRead these operating instructions before commissioning the device. Knowledge of the oper-
ating instructions is an element of proper use.
NOTICE
Comply with conditions and regulations!
ÄObserve the locally applicable legal regulations and the rules of the employer's liability insur-
ance association.
2.2 Foreseeable misuse
Any use other than that defined under "Intended use" or which goes beyond that use is considered im-
proper use.
In particular, use of the device is not permitted in the following cases:
• in rooms with explosive atmospheres
• in circuits which are relevant to safety
• for medical purposes
NOTICE
Do not modify or otherwise interfere with the device!
ÄDo not carry out modifications or otherwise interfere with the device. The device must not be
tampered with and must not be changed in any way.
ÄThe device must not be opened. There are no user-serviceable parts inside.
ÄRepairs must only be performed by Leuze electronic GmbH + Co. KG.

2.3 Competent persons
Connection, mounting, commissioning and adjustment of the device must only be carried out by competent
persons.
Prerequisites for competent persons:
• They have a suitable technical education.
• They are familiar with the rules and regulations for occupational safety and safety at work.
• They are familiar with the operating instructions for the device.
• They have been instructed by the responsible person on the mounting and operation of the device.
Certified electricians
Electrical work must be carried out by a certified electrician.
Due to their technical training, knowledge and experience as well as their familiarity with relevant standards
and regulations, certified electricians are able to perform work on electrical systems and independently de-
tect possible dangers.
In Germany, certified electricians must fulfill the requirements of accident-prevention regulations BGV A3
(e.g. electrician foreman). In other countries, there are respective regulations that must be observed.
2.4 Disclaimer
LeuzeelectronicGmbH+Co.KG is not liable in the following cases:
• The device is not being used properly.
• Reasonably foreseeable misuse is not taken into account.

3 Device description
3.1 Device overview
3.1.1
About the DCR40 scanengine
The code reader is based on a scan engine with CMOS imager with integrated decoder for all of the most
popular 1D and 2D codes such as DataMatrix, Aztec, QRCode, 2/5 Interleaved, Code39, Code128, UPC/
EAN etc.
3.1.2
Stand-alone operation
The scan engine is operated as a single "stand-alone" device. It is equipped with a 12-pin FFC connector
for the power supply electrical connection, the interface, the trigger input, and the switching output.
3.2 Performance characteristics
• High-performance miniature CMOS imager scan engine
• Compact design for simple integration, even in constrained spaces
• Reading of extremely small high-density codes and recording of standard codes in a large reading area
using a special optical system
• Reading of shiny surfaces using a gloss reduction process
• Excellent decoding characteristics
• Clearly visible alignment LED
• RS 232 interface, triggering input, switching output

Mounting

4 Mounting
The DCR40 scan engine can be attached at two M2.5 through-hole mounting tabs.
Optionally, the DCR40 scan engine is available without mounting tabs.
In addition, two 2mm deep inserts for M1.8 self-tapping screws are provided on top of the scan engine.
4.1 Selecting a mounting location
NOTICE
The size of the code module influences the maximum reading distance and the width of the
reading field. Therefore, when selecting a mounting location and/or the code label, take into ac-
count the different reading characteristics of the scanner with various code modules.
NOTICE
Observe when choosing the mounting location!
ÄMaintaining the required environmental conditions (temperature, humidity).
ÄPossible soiling of the reading window due to liquids, abrasion by boxes, or packaging mate-
rial residues.
ÄLowest possible chance of damage to the scanner by mechanical collision or jammed parts.
ÄPossible extraneous light influence (no direct sunlight).
The best read results are obtained when
• the reading distance lies in the middle area of the reading field.
• there is no direct sunlight and extraneous light is avoided.
• the bar code labels are of good print quality and have good contrast ratios.
• you do not use high-gloss labels.
• the bar code or the Data Matrix code is moved past the reading window with an angle of rotation of 10°
to 15°.
• the red light beam is narrowed down for its respective reading task in order to avoid reflections on shiny
components.
NOTICE
The front beam exit of the device is almost vertical to the optics. The code label must be rotated
by >10° to avoid a total reflection of the red light beam in the case of glossy labels.
