The RS51B0-TBSNWR04 is a Zebra wearable ring scanner built around the SE4710 imager, reading both 1D and 2D symbologies — including Code 39 down to 3 mil, PDF417 from 5 to 6.7 mil, and DataMatrix from 10 mil — across a 42-degree horizontal by 28-degree vertical field of view, with 360-degree roll tolerance and 60-degree pitch and skew angles. Rated IP65 and tested to multiple 6 ft drops to concrete across the operating temperature range, it handles up to 107639 lux of ambient light while weighing just 2.47 oz in a 2.4 in by 1.1 in by 0.8 in body. Bluetooth connectivity removes any cable to the host, and programmable LEDs on the back provide scan-status feedback. Supported symbologies span Code 128, Code 93, UPC/EAN, GS1 DataBar, Aztec, QR Code, MaxiCode, and Chinese Sensible (Han Xin), among others. The RS51B0-TBSNWR04 fits picking, sorting, packing, inventory, manufacturing, retail, and field service deployments.
