Laser scanners use a single point of light to read 1D barcodes, while imagers use a camera sensor to capture an entire image, allowing them to read 1D, 2D, and damaged codes.
Machine Vision - Bar Code Readers Component Intelligence
High-speed optical scanning and vision-based identification for industrial automation.
What are Machine Vision - Bar Code Readers components?
Industrial bar code readers integrate high-speed optical sensors and image processing to automate data capture. Selection depends on symbology support (1D/2D), read range, motion tolerance, and industrial communication protocols like PROFINET or EtherNet/IP.
How to Choose Machine Vision - Bar Code Readers Components
Selecting the right reader requires balancing optical performance with the physical constraints of your production line.
Symbology Support
Confirm if the application requires 1D linear codes, 2D matrix codes (DataMatrix, QR), or DPM (Direct Part Marking) reading capabilities.
Communication Protocol
Ensure the reader supports your PLC's native protocol, such as EtherNet/IP, PROFINET, or Modbus TCP, to minimize integration middleware.
Motion Tolerance
High-speed lines require readers with high frame rates and global shutter sensors to prevent motion blur during image capture.
Environmental Rating
Check IP ratings (e.g., IP65/67) if the reader will be exposed to dust, moisture, or washdown cycles in food and beverage processing.
Read Range & FOV
Calculate the required field of view and working distance to ensure the code remains within the focal plane during the scan window.
