These extra tough and durable scanners read barcodes and 2D codes—and welcome heavy-duty use under extreme conditions. They are especially suited for applications for manufacturing and warehousing. They come with a free, five-year warranty when you register your purchase.
Takes Licks, Still Clicks
The GT20 model series meets the highest impact standard—tested to withstand 60 drops at 2 meters (6.5 ft).
Dust- and Water-Tested
The GT20 has a P code rating of IP65, so you can use it with confidence in severe environments of dust and moisture.
Good in Hot and Cold Extremes
GT20 works well in temperatures ranging from -20°C to 50°C (-4°F to 122°F). This makes it ideal for scanning in cold storage and in many areas that are not temperature-controlled.
With Advanced Scan Plus (barcode models) and Area Scan (2D models), you are assured of quick and accurate readings for multiple, continuous scanning.
Reads LCD Screens
GT20 can read barcodes on PC screens and tablets, bringing digital convenience that reduces reliance on paper.
Clears Up Dirty Codes
The GT20 ably reads poorly printed, blurry, and dirty codes—especially useful in locations where dust and humidity can create a “smudge factor.”
Wide Codes Too
Enjoy quick, successful scanning of wide barcodes.
- ITF-14 and GS1-128 (EAN-128) codes common on invoices by public utilities and medical providers;
- Code 39 barcodes for labels.
Wins Operators’ Love
See, hear, feel confirmation.
Even in noisy environments, you’ll know a scan has been successful with a double-LED signal, a buzzer, and a vibration.
Compact and lightweight (180 grams/6.3 ounces)
Although super tough and durable, the GT20 is among the lightest in its class. The ergonomic design makes it a pleasure to use, even for extended periods.
Hang In There
GT20 has a hook so it can be hung overhead for ease of accessibility on lines and in areas where multiple tools are used.
“Lock and Code”
The connector cover is resilient to prevent breaking and firmly locks the cord to the scanner body for long-lasting resistance to wear and tear.
Smart Choice for Smart Devices
Assign the function you need to these Magic Key modes:
- Re-transfer of previously sent data
- Transfer designated characters
- Alternate between two predetermined codes (GT20Q models)
Using the free Scanner Setting software on your PC you can easily configure settings such as reading condition and data format according to targeted objects.
When the operator detects a non-conforming object, such as a product on a production line, the GT20 can capture an image and send it to the host for verification.
