Barcode scanners are light emitting gadgets that are accustomed to read barcodes. Usually attached to a computer or laptop computer via PS2 or RS-232, the info collected is stored on a pc for processing or storage space. It really is now found in many different industries such as retail or production.
They have been out there for several years now with brand-new variations of barcode scanners available every year. The prices may differ from as low as $50.00 to as high as thousands of dollars. Just how do you pick an excellent barcode scanner?
To answer that question, it is necessary you know there are 2 major classes of barcode scanner manufacturer , image-centered and laser-centered. Image-centered barcode scanners make use of a camera usually embedded in a barcode scanner. The surveillance camera will catch the images and processed by complex image techniques to decode the barcodes. Laser-structured barcode scanners uses mirrors and lenses to learn the barcodes.
Laser beam barcode scanners are often more expensive than image-centered scanners. They have their own benefits and drawbacks. An image-centered barcode scanner don’t have internal movable parts therefore are even more resistant to drops or knocks than laser beam barcode scanners. Also, image-centered barcode scanners have got a shorter scanning range (4 to 10 inches) in comparison to laser barcode scanners. On the other hand, laser beam scanners are more prone to wear and tear due to their lenses. They not only have an extended scanning length (up to 24 inches) but also are in a position to scan from a wider position from the barcode.
Remember that the scanning length for both image-based and laser beam barcode scanners have already improved dramatically through the years and I wouldn’t be surprised if a barcode manufacturer promises an image-structured scanner includes a scanning distance of 24 ins.
Here are some questions you need to ask yourself before obtaining a barcode scanner. How big is scanner required? Type of environment the barcode scanner will become using (outdoors, shop, warehouse)? The scanning length required? Are they to be used hands-free or hand-kept? Your budget?
So my suggestion is if you need a barcode scanner for long range scanning, get yourself a laser barcode scanner. For brief range scanning, make use of an image-structured barcode scanner like a CCD barcode scanner. The surroundings as I asked previously also plays a significant part. If the barcode scanner has been used outside or in durable environments where it is expected to have a drop or knock or two, then it is best to obtain an image-based barcode scanner. If it were for instance being found in a retail store, then a laser beam barcode scanner would be the best choice.
There are such a multitude of barcode scanners available that I simply can’t clarify completely in this post. If you are in doubt, seek advice from the barcode manufacturers such as for example symbol or metrologic who’ve sales consultants who are able to do an analysis of the type of barcode scanners needed by your business.
