Barcode Readers

A barcode is a machine-readable representation of data related to the object it is attached to. Barcode readers read these codes in order to track the object throughout its lifecycle. Popular barcode symbologies include UPC-A, Code 39, Code 128, Interleaved 2 of 5, Data Matrix, QR, MaxiCode, and Aztec.

There are a few main reasons companies use barcodes:

• They’re universally understood
• They provide automation and speed
• They allow for traceability

Common types of barcode readers include laser scanners and image-based readers. Laser scanners can produce 1,300 scans/second and read 1-D codes from relatively long distances with the use of special optics. Image-based barcode readers have higher read rates than laser scanners, read 2-D and omnidirectional codes, and capture images of codes for data analysis, process improvement, and barcode quality feedback.

Cognex industrial, image-based barcode readers decode 1D and 2D codes, from printed labels to the hardest to read direct part mark (DPM) codes in manufacturing and logistics applications. Industry-leading read rates, advanced technology, modular options, and easy setup help reduce costs, optimize performance, increase throughput, and control traceability.

There are multiple types of barcode scanners, including fixed-mount and handheld. Companies often choose handheld barcode readers when they need flexibility and freedom of movement. 

Typically, manufacturing environments in industries such as automotive, medical device, electronics, aerospace, and product security require rugged, high performing, and easy to use handheld barcode reading technology to ensure component traceability and productivity.

Cognex’s DataMan handheld barcode readers can accommodate 1D and 2D label-based barcodes as well as direct part marked (DPM) codes for the widest variety of surfaces and marking methods. They are equipped with the latest patented technology, rugged housing, and modular communication options to withstand the harshest manufacturing and logistics environments.

Do more with your smartphones and tablets by putting them to work across your entire enterprise, from in-house retail and light industrial barcode reading applications to harsher warehouse and factory floor environments. The Cognex Mobile Barcode Software Development Kit (SDK) and MX Series mobile terminals offer comprehensive, end-to-end handheld mobile scanning solutions, while achieving best-in-class 1D, 2D, and direct part mark (DPM) barcode reading performance.

Barcode verification is the process of grading the quality of 1D, 2D, and direct part mark (DPM) codes. An increasing number of regulated industries require barcode verification. Barcode verifiers provide guidance through the marking process to create codes which meet minimum quality standards. Cognex barcode verifiers use high quality optics, advanced algorithms, and simple software to demonstrate compliance to industry standard guidelines.
