6 Mounting
The code reader can be mounted in the following ways:
• Mounting using four M4 mounting threads on the rear of the device
• Mounting using two M4 mounting threads on the rear of the device (devices with stainless steel hous-
ing)
• Mounting using two M4 mounting threads on each of the side surfaces of the device
• Mounting on a 12 mm rod using the BTU 320M-D12 mounting system
• Mounting on the BT 320M mounting bracket
NOTICE
Ä
Mount the device on a metal mounting bracket.
6.1 Determining the mounting position of the code reader
6.1.1 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 suitable code label, take
into account the different reading characteristics of the code reader with various code modules.
NOTICE
Observe when choosing the mounting location!
Ä
Make certain that the required environmental conditions (humidity, temperature) are main-
tained.
Ä
Avoid possible soiling of the reading window due to liquids, abrasion by boxes, or packaging
material residues.
Ä
Ensure the lowest possible chance of damage to the code reader through mechanical colli-
sion or jammed parts.
Ä
Avoid possible ambient light influence (no direct sunlight).
Take the following factors into account when selecting the correct mounting location:
• Size, orientation, and position tolerance of the bar codes or Data Matrix codes on the objects to be
scanned.
• The reading distance resulting from the code size and code type (see chapter 6.1.3 "Determining the
reading distance").
• Time of data output.
Position the device in such a way that, taking into consideration the time required for data processing
and the conveyor belt speed, there is sufficient time to e.g. initiate sorting operations on the basis of the
read data.
• The permissible line lengths between code reader and host system depending on which interface is
used.
• Visibility of the control panel and access to the control buttons.
• No direct sunlight and/or no strong ambient light on the code that is to be read.
