Fixed Mount Barcode Scanners

Where Fixed Mount Scanners Fit in Automation Architecture 

Fixed mount scanners operate as part of a larger automation ecosystem, interacting with: 

• Sensors (photoelectric / proximity) for trigger signals 

• PLCs or industrial controllers for logic execution 

• Conveyor systems for material movement 

• Vision or inspection systems for validation workflows 

• ERP/WMS/MES platforms for data capture and traceability 

In this setup, the scanner is not just reading a barcode—it is enabling the following:

• Product identification 

• Routing decisions 

• Sorting logic 

• Batch tracking 

• Process validation 

Any delay or misread at this level directly affects the entire system flow. 

Understanding Performance in Fixed Mount Scanning 

Read Rate Under Motion Conditions 

Unlike handheld scanning, fixed mount systems must decode barcodes while the object is moving. 

Performance depends on: 

• Object speed (m/s) 

• Exposure time 

• Motion tolerance of the scanner 

• Trigger timing accuracy 

A mismatch results in missed reads or duplicate scans. 

Decode Capability in Real Conditions 

In automated environments, barcode quality varies significantly due to: 

• High-speed printing inconsistencies 

• Surface curvature or reflection 

• Label damage during handling 

Advanced fixed scanners use high-resolution imaging and algorithm-based decoding to reconstruct incomplete or low-contrast codes. 

Field of View and Depth of Field 

The scanner must be configured to cover the entire barcode area within the conveyor width. 

• Field of View (FOV) determines coverage width 

• Depth of Field (DOF) determines reading range 

Incorrect configuration leads to: 

• Missed barcodes 

• Multiple reads 

• Need for re-scanning zones 

Lighting and Environmental Control 

Industrial scanners integrate: 

• Built-in illumination systems 

• External lighting compatibility 

This ensures consistent performance across: 

• Low light 

• Reflective surfaces 

• Variable ambient conditions 

Communication and Latency 

Fixed mount scanners must transmit data in real time to control systems. 

Typical interfaces include the following:

• Ethernet (TCP/IP, PROFINET, EtherNet/IP) 

• RS232 / Serial communication 

• Digital I/O for trigger and feedback 

Low communication latency is critical to ensure synchronization with conveyor logic and sorting decisions. 

Types of Fixed Mount Barcode Scanners 

1D Fixed Mount Scanners 

Used for high-speed reading of linear barcodes in environments with consistent label quality. 

2D Fixed Mount Scanners 

Capable of decoding both 1D and 2D symbologies, including QR and Data Matrix.
Required for traceability, compliance, and serialization applications. 

Area Imaging Fixed Scanners 

Capture a full image of the scanning zone, allowing: 

• Multi-code reading 

• Orientation-independent scanning 

• Higher tolerance for positioning errors 

Long-Range Fixed Barcode Systems 

Designed for applications where the scanner cannot be placed close to the object.
Used in large conveyor systems and industrial setups. 

High-Speed Conveyor Scanners 

Engineered specifically for high-throughput environments, where objects move continuously and scanning must occur within milliseconds.

DDAPL Approach to Fixed Mount Scanning Solutions 

Fixed mount scanning is not a device-level decision — it is a system-level integration problem. 

DDAPL evaluates: 

• Conveyor speed and layout 

• Barcode position and orientation 

• Triggering mechanism 

• Required read rate and redundancy 

• Integration with control systems 

Based on this, the scanner is selected and positioned to ensure consistent read performance within the actual operating environment. 

Enabling Reliable Automation Through Accurate Data Capture 

In automated systems, barcode scanning is often the first point of data capture. 

If this step fails: 

• Routing decisions are affected 

• Sorting logic breaks 

• Traceability gaps are created 

Fixed mount barcode scanners ensure that data capture remains: 

• Continuous 

• Accurate 

• Synchronized with system logic
