High-Speed Laser Scanning Performance
Featuring laser scanning technology, the MS851B has the automatic scanning ability with a scan rate of up to 104 scans per second. It also has the ability to capture long range 1D barcodes, even damaged or poorly printed barcodes. This device enhances workflow efficiency at an affordable price.
Move without Restrictions
The MS851B supports Bluetooth® dual-mode technology (Bluetooth LE® V4.2 & Bluetooth® 2.1+EDR, Class 1) to give you the freedom and bring your business the flexibility. It is compatible with any smartphone, tablet, or computer–the MS851B pairs easily to any mobile device or PC. Besides, it allows users to transmit data to the host from up to 100 meters from the base.
Flexibility with Cradle Accessory
This MS851B wireless scanner has a cradle accessory that supports auto Bluetooth® pairing and it has the ability to switch between trigger or presentation mode automatically. When it is out of range reading in Auto Mode, the scanned data will be saved into the MS851B memory buffer automatically and transmit to the host when back to the wireless coverage. Moreover, MS851B can be set to batch mode reading, all the scanned data will be stored in a memory buffer and upload to your devices at your own convenience.

Moreover, the built-in long lifecycle trigger of 10 million times guarantees a continuous productivity for the best reliability. This scanner can be used in the most practical way depending on the long-range scanning task in various solutions in retail and inventory applications.
TAA Compliant Barcode Scanners
TAA refers to the Trade Agreements Act, which is a law that was passed for the purpose of making international trade more open and fair. One of the main requirements of the TAA is products purchased by the United States government can only be made in the U.S. or by a designated country such as Taiwan.
Founded in 1979 in Taiwan, Unitech is a global provider of AIDC technologies with over 40 years of experience. Our factories were built in Taiwan, and all the SMT and assembly are done in Taiwan as well. We offer a series of quality barcode scanner products to comply with the Trade Agreements Act (TAA) for U.S. government GSA (General Services Administration) Schedule contracts
