Configured as a lanyard-worn unit, the Zebra RS51B0-LBLNWR is a wireless wearable ring scanner weighing 2.47 oz in a body measuring 2.4 in long, 1.1 in wide and 0.8 in deep. It uses an SE4710 imager with an LED light source to capture both 1D and 2D symbologies, including Code 39, Code 128, Code 93, UPC/EAN, GSI DataBar, PDF417, Micro PDF417, DataMatrix, QR Code, Micro QR, Aztec, MaxiCode and Chinese Sensible (Han Xin), along with OCR-A and OCR-B. Class 1 Bluetooth wireless connectivity supports roaming up to 300 feet/91.44 m from a paired host device, with NFC tap-to-pair available for compatible Zebra mobile devices. The modular two-piece trigger assembly separates from the scanner body to support per-worker hygiene practices. REACH and RoHS compliance apply, and the unit carries a 1-year limited warranty.
