Fitted with the SE4770 imager, the Zebra RS51B0-TBDNWR is a double-sided, Class 1 Bluetooth wearable ring scanner that reads both 1D and 2D barcodes across an extensive symbology set — Code 39, Code 128, Code 93, UPC/EAN, PDF417, DataMatrix, QR Code, Aztec, MaxiCode and OCR-A/OCR-B among them. NFC tap-pairing enables instant connection to compatible Zebra devices, while Class 1 Bluetooth allows roaming up to 300 feet/91.44 m from the host device. The scanner measures 2.4 in long, 1.1 in wide and 0.8 in deep, and weighs 2.47 oz, supporting wear on a finger, back of hand or lanyard on either hand. A modular two-piece trigger assembly separates from the scanner body to allow per-worker trigger assignment. REACH and RoHS compliant, the RS51B0-TBDNWR carries a 1-year limited warranty.
