Barcode / RFID / Vision products are devices that identify a unique item, type of item, or code and convert this information into useful data. Examples of identification devices are barcode scanners, RFID R/W devices, and vision systems. Mounting systems are available for many types of devices.
With the ever-increasing pace of manufacturing processes and the logistics needed for on-time and accurate delivery, asset management with real-time inventory levels and product tracking has become a vital component of industrial automation. Identification systems are used to identify and track a product or part as it moves through the manufacturing and/or delivery process. This added visibility provides many benefits, including:
The three main types of technology used in industrial identification are RFID, vision systems, and optical identification, with barcode scanners and RFID devices being the most prevalent.
Barcode scanners allow a code, such as a 1-dimensional barcode, 2-dimensional QR code or other non-human-readable code to be read, decoded and converted to a usable format. This code is then sent to an intelligent device such as a PLC or PC over a network. A selection of Code brand scanners is available to read barcodes for specific applications.
RFID (Radio Frequency IDentification) devices use radio frequencies to read and transmit data. This technology can be used to identify and track objects as they travel through an automated process. RFID Read-Write modules exchange data with RFID tags, affixed to the objects, that contain identifying information. The RFID Read-Write units can also communicate with an intelligent device, such as a PLC or computer, over a network such as IO-Link.

Vision sensors detect variances in products/objects by comparing the current image of the product/object with the satisfactory stored image to determine a "pass/fail" or "good/no good" result.
Vision lighting provides the right amount of contrast, brightness, and uniformity to an imaging surface in order to capture a good image of the code or object. Lighting devices available include:
Device mounting systems are assembled using available components and can be configured to mount vision cameras, lights, sensors, scanners and other devices. They allow for precise adjustment and ease of equipment installation.
