The Zebra RS51B0-TEDNWR is a double-sided, Bluetooth wearable ring scanner built around the SE4770 imager, delivering 1D, 2D and OCR capture in a body measuring 2.4 in long, 1.1 in wide and 0.8 in deep at just 2.47 oz. Class 1 Bluetooth enables wireless operation up to 300 feet (91.44 m) from the host device, and NFC tap-to-pair works with compatible Zebra mobile devices. Supported 1D symbologies include Code 39, Code 128, Code 93, UPC/EAN, GSI DataBar and I 2 of 5; 2D coverage extends to PDF417, DataMatrix, QR Code, Aztec, MaxiCode and Chinese Sensible (Han Xin); OCR-A and OCR-B round out the decode set. The modular two-piece trigger assembly separates from the scanner body for per-worker hygiene practices. REACH and RoHS compliant, the RS51B0-TEDNWR carries a 1-year limited warranty.
