Whether your workers spend their days moving products through your warehouse or retail store, or moving packages through distribution centers and onto trucks for delivery, every time they need to set an item down to check a paper work order or scan a barcode with a handheld device, their productivity decreases. But when you put the small and lightweight RS4000 1D ring scanner on the fingers of workers who are using Zebra’s WT6000 wearable mobile computer, your workers are free to keep their hands and eyes on the items they are handling. The result? Worker productivity increases. And a split-second press of the RS4000 trigger verifies task accuracy and provides the real-time inventory visibility you need to eliminate out-of-stocks.

Two Scanning Modes

Workers can either press the trigger button once to scan a single barcode or keep the trigger depressed to continuously scan barcodes.

Capture Virtually any Barcode in Practically any Condition

With our advanced scanning algorithms, your workers can capture scratched, dirty, damaged and poorly printed barcodes, first time, every time.

A Patented Liquid Polymer Scan Element with a Lifetime Warranty

Friction and wear are eliminated, maximizing uptime and worker productivity, along with a low total cost of ownership.

A Bright Scan Line

The easy to see scan line ensures easy aiming for first-time capture of barcodes in virtually any lighting condition. And with an oversize LED light, users can easily see when a scan is successful.

Diecast Zinc Scan Engine Chassis, Single Board Construction and Scan Engine Isolation

Superior impact protection for the scan engine improves reliability in the event of a drop.
