Fitted with the SE4710 imager and Class 1 Bluetooth, the Zebra RS51B0-LESNWR is a single-sided wearable ring scanner that roams up to 300 feet/91.44 m from its host device — a range that suits pairing with vehicle-mount computers or laptop dongles as readily as enterprise handhelds. It captures 1D and 2D barcodes as well as OCR-A and OCR-B text, covering symbologies including Code 39, Code 128, UPC/EAN, PDF417, DataMatrix, QR Code, Aztec, MaxiCode, and Chinese Sensible (Han Xin). NFC tap-to-pair support allows instant connection to compatible Zebra devices. The scanner measures 2.4 in long by 1.1 in wide by 0.8 in deep and weighs 2.47 oz, with multiple back-mounted LEDs that signal directional guidance. A modular two-piece trigger assembly separates from the scanner body to support per-worker hygiene practices. REACH and RoHS compliance are confirmed, and the unit carries a 1-year limited warranty.
