Configured as a back-of-hand mount unit, the Zebra RS51B0-LBBHWR is a Bluetooth wearable ring scanner built around the SE4710 2D area imager, capturing both 1D and 2D symbologies including Code 39, Code 128, UPC/EAN, PDF417, DataMatrix, QR Code, Aztec, and OCR-A/OCR-B. At 2.47 oz and measuring 2.4 in long by 1.1 in wide by 0.8 in deep, the unit suits all-day wear in warehouse, distribution, and retail environments. Class 1 Bluetooth supports a roaming range of up to 300 feet/91.44 m from the host device, and NFC tap-to-pair enables instant connection with compatible Zebra mobile devices such as the WT6000 and TC52. An LED light source and rear-facing directional LEDs support both scanning feedback and worker navigation guidance. The modular two-piece trigger assembly separates from the scanner body to allow per-worker assignment.
