At 2.47 oz and measuring 2.4 in long, 1.1 in wide and 0.8 in deep, the Zebra RS51B0-LBDNWR is a single-finger wearable ring scanner built around the SE4710 imager for combined 1D and 2D barcode reading. Class 1 Bluetooth with a range of up to 300 feet/91.44 m connects it to enterprise-class host devices while keeping workers cable-free, and NFC tap-to-pair enables instant pairing with compatible Zebra devices. Symbology coverage spans Code 39, Code 128, Code 93, UPC/EAN and GSI DataBar in 1D; PDF417, Aztec, DataMatrix, QR Code, MaxiCode and Micro PDF417 in 2D; and OCR-A and OCR-B for optical character recognition. The modular two-piece trigger assembly separates from the scanner body to allow per-worker assignment, while multiple rear LEDs provide directional guidance. REACH and RoHS compliance apply, and the unit carries a 1-year limited warranty.
