How to Select the Right Laser-Generated 2D Bar Code Reader

How to select the right laser barcode scanner? Starting from practical needs, this article analyzes key parameters, suitable scenarios, and brand comparisons, to help you match your industrial barcode scanning needs accurately, and improve scanning efficiency and stability.

Why do we need laser-based QR code technology?

Nowadays many factories and logistics warehouses use invisible QR codes, which cannot be read with ordinary scanners.Lasers can read codes that are scratched, worn, or even covered, and can penetrate through materials.But the market is full of all kinds of products, and choosing the wrong one is easy. You may end up with a scanner that doesn't work right or one that breaks down after a short time, wasting your budget.

The core skill is to select the equipment based on demand.

Let's look at the application environment first.

For high-speed production lines, you need a scanner that can scan more than 300 times per second. If the warehouse environment is dusty, you should look for a scanner with a high IP rating, with IP65 or higher being more durable.A small secret: Equipment with temperature compensation functions works better in cold storage facilities.

We're keeping a close eye on these three factors.

Resolution is like the 'eyesight' of a machine. If it's less than five megapixels, you might as well skip it.The depth of field is also an important consideration, with the minimum standard being 0.2 to 1.5 meters.When testing, remember to try out different types of labels (matte, glossy, metallic) as some equipment is picky.

Don't be taken in by brand name hype.

Imported brands do have the advantage of stability, but local products have improved rapidly in the past two years.The key things to look for are three-year warranties and local service centers.When a salesperson recommends a top-of-the-line model, ask him, "We only vacuum 500 times a day. Is an industrial-strength machine overkill?

Real testing is more important than parameters.

They brought along the most worn-out QR codes from their own homes to test, deliberately scanning them at a 45-degree angle or through a plastic bag.The best equipment can work stably in strong light, and if it encounters a blurry code, it will prompt the user to scan again, rather than reporting incorrect data.Remember, only equipment that can solve your problems is good equipment.

How can we make the most of maintenance costs?

Don't just look at the price of the equipment; the cost of consumables and maintenance is the hidden cost.The life of a laser head starts at 100,000 hours, and it costs more than NT $ 1,000 to replace.If you can find a modular design, you can replace the broken part, which is much more convenient than sending the whole machine back to the factory for repair.
