Product Description

Gain a Performance Advantage

The SR31T was designed to maximize user productivity. Area imager versions integrate Intermec’s EA30 or EA31 imaging engines for a level of scanning speed and responsiveness historically found in only the fastest laser scanners. Extreme motion tolerance (up to 500 in/sec) and omnidirectional reading result in effortless, consistent scanning—at any orientation.

With an uncanny ability to read poorquality codes, the SR31T can help you avoid error-prone manual data input routines. Read codes that are damaged, partially obscured, off-angle, colored, high resolution, or low contrast. And thanks to VESTA, Intermec’s patented scanning algorithm, read range is increased by an average of 60 percent when scanning EAN/UPC and Code 39 codes.

Ready for Tomorrow

The SR31T high performance imager was developed to address your scanning needs now and well into the future. Not only can it read all common 1D, PDF, 2D, and postal symbologies—it can also reliably read these codes from smartphone, tablet, and computer displays.

With innovative area imaging technology, snappy scanning is just the beginning. Capture real-time video and images, read multiple codes in a single scan, scan documents or ID cards, even perform advanced data parsing routines—all with one device.

Reliability for the Long Term

Performance isn’t just about speed; it’s also about longevity in demanding environments. Here again, the SR31T sets a new ruggedness standard for general purpose devices, with an IP53 rating for protection against dust and water ingress, and an impressive two meter (6 ft) drop specification to concrete.

Easy to Install, Easy to Use

Integrating the SR31T into your environment is truly plug-and-play, thanks to its auto-adapting capabilities. Simply connect the scanner to the host device and start scanning. If new application requirements arise, just change out the interface cables—not the scanner itself. And there’s no need to update the scanner configuration when interfaces change, because the SR31T is smart enough to adjust itself on-the-fly. This flexibility reduces device costs and complexity, both for you and your IT staff.

The SR31T also includes distinctive design elements that add to its versatility. Unique touches, like the over-sized LED light pipe on the scanner head, provide bright 360-degree feedback in any lighting condition—and its color can be personalized to match the décor of your environment.

A complete range of accessories ensure SR31T will fit into your scanning application. Scan stands and mounts enable hands-free presentation mode canning, and a variety of interface cables guarantee easy communication to your host device.

Scanner Configuration Made Easy

The SR31 can be quickly and easily customized with Intermec’s exclusive EasySet™ PC programming tool. In just a few clicks, this Windows-based utility can print configuration bar codes; adjust security settings; activate or disable symbologies; and alter beeper, vibrate or LED settings. Even sophisticated data editing routines can be set. When you’re satisfied with the settings, simply create a configuration bar code to quickly program additional scanners to match.
