Configured as a lanyard-worn unit in black and silver, the Zebra RS51B0-TBLNWR is a wearable Bluetooth ring scanner built around the SE4770 imager for combined 1D and 2D scanning. At 2.47 oz and measuring 2.4 in long, 1.1 in wide, and 0.8 in deep, it carries a minimal on-body footprint suited to extended shift wear. Class 1 Bluetooth enables wireless operation at ranges up to 300 feet/91.44 m from the host device, and NFC tap-to-pair is supported on compatible Zebra hardware. Symbology coverage spans Code 39, Code 128, Code 93, UPC/EAN, PDF417, DataMatrix, QR Code, Aztec, MaxiCode, and OCR-A/OCR-B, among others. A modular two-piece trigger assembly separates from the scanner body to support per-worker hygiene practices. The RS51B0-TBLNWR carries REACH and RoHS environmental compliance and is backed by a 1-year limited warranty.
