Fixed code readers for industrial identification
Fixed code readers decode 1D, 2D and direct part marks and send the result to the PLC or production system. Code and cell size, mark quality, working distance, movement and lighting determine which reader can provide a stable result at the required production speed.

Available reader families
How the code reader families differ
The families differ in sensor, optics, lighting, connection, working distance and field of view. Compact readers suit defined reading positions, while the larger platforms provide more image detail or coverage for difficult marks and logistics flows.

Specifications that matter when selecting a code reader
Resolution is only one part of a stable read. The code dimensions, optical geometry, surface, movement, lighting and result communication all affect the available reading margin.
Code and cell size
The code type, outer dimensions and smallest module or cell determine how much image detail is required. Print and marking variation reduce the available margin.
Small cells require sufficient pixels and focus margin
Working distance and movement
Working distance, viewing angle, field of view, position tolerance, product speed and exposure time determine whether the code remains sharp and fully visible.
Motion blur reduces contrast at module edges
Surface and lighting
Gloss, curvature, engraving depth and material texture determine whether integrated lighting is sufficient or external lighting is needed.
Lighting creates contrast before decoding
Trigger and communication
The trigger source, result timing, I/O, network interface and data format must match the PLC, PC or traceability system.
No-read handling is part of the machine interface
Applications for fixed code readers
A decoded result for each reading event
- ●Traceability: linking a product, batch or serial identity to the production record.
- ●Process routing: selecting a machine step or recipe from the decoded value.
- ●Verification: confirming that the expected code is present and readable.
- ●Logistics: identifying moving cartons, totes and parcels within a controlled reading zone.
Alternative inspection architectures
Fixed reader or broader vision inspection
The required output is an identifier and read status
A fixed code reader decodes the identifier and sends the value and read status directly to the control system.
Print, position or dimensions must also be inspected
A smart camera is suitable when code reading is one result within an inspection that also checks print, position, dimensions or other visual features.
DPM quality or surface variation affects the result
The DPM reading guide explains how mark quality, surface and lighting affect DPM readability.
Complete reading setup
Reading reliability depends on the complete image
Reader, optics, lighting, trigger and communication form one system. A technically decodable code can still fail in production when reflection, movement or position variation removes the usable contrast.

Frequently asked questions
Common questions about industrial code reading
Which code types can a fixed reader decode?
The supported symbologies depend on the selected reader. The Hikrobot families cover common industrial 1D and 2D codes, with models intended for direct part marks. The required code standard and data format therefore form part of the model comparison.
Why is cell or module size important?The smallest bar or cell must occupy enough sensor pixels under the real working distance and field of view. Print growth, blur, focus tolerance and perspective reduce the effective margin.
Can integrated lighting read every surface?No. Integrated light is convenient, but glossy foil, curved metal, deep engraving and low-contrast marks may need another angle, wavelength, polarization or external illumination.
How do I read moving products?Moving products require reliable triggering and an exposure time short enough to keep module edges sharp. Reader sensitivity, available light, product speed and position variation determine the available margin.
When is a smart camera more suitable?A smart camera is suitable when the system must inspect more than the decoded value, such as print quality, label position, component presence or dimensions. Some code reader models also support training with representative codes to accommodate variation in contrast, damage and mark quality.
Which information helps with reader selection?Useful information for reader selection includes representative good and difficult codes, code and cell dimensions, material and surface finish, working distance, field of view, product speed, position tolerance, mounting angle and required interface.
