Long-Range Scanning

The MS320 is a long-range barcode scanner that reads all linear barcodes. Its powerful scan engine makes its performance comparable to that of more expensive laser barcode scanners. With this device you can reliably and consistently scan barcodes up to a foot away.

The comfortable and ergonomic design of the MS320 makes it easy to operate. Whether it’s picked up once an hour or used consistently for an entire shift, the MS320’s compact and lightweight form factor will prevent user-fatigue and simplify scan-intensive applications.

This barcode scanner is available in three different interface options–USB, keyboard wedge, and serial. The interface cables are easily interchangeable, making it suitable for a wide variety of computer systems. Easy plug-and-play installation means your team will be up and running in no time.

For added flexibility, the MS320 is also available with a hands-free stand.

In addition to reading all major 1D barcodes, the MS320 also reads the 2D barcode PDF417.

The Unitech Service Guarantee backs this powerful corded barcode scanner for five years. However, the MS320’s rugged enclosure makes it highly unlikely you’ll ever have to send it in for repair. The MS320 is a rugged barcode scanner, meaning it is built to last. Equipped with a special sealing that repels moisture and dust and built to withstand repeated 5-foot falls to concrete, the MS320 is a bold investment in your company’s future.
