Zebra RS51C0-LESNWR Bluetooth Ring Scanner with SE4710 1D/2D Imager
Overview
The Zebra RS51C0-LESNWR is a wearable Bluetooth ring scanner built for warehouse, retail, and field operations where both hands need to stay free. Pairing the proven SE4710 1D/2D imager with Bluetooth 5.2, this single-trigger ring scanner mounts on a finger and connects wirelessly to Android mobile computers or wearable host devices — letting workers scan, pick, and verify without ever breaking workflow to grab a handheld. If you run a WMS environment where scan latency or awkward re-grips translate directly to throughput loss, the RS51C0-LESNWR is designed to close that gap.
Part of Zebra's mobile computing and scanning line, the RS5100 series targets demanding productivity environments where ergonomics matter as much as scan reliability. The compact form factor — 2.67 in. L × 1.10 in. W × 0.83 in. H, weighing just 2.47 oz — keeps fatigue low across an 8–10 hour shift.
Key Features
- SE4710 1D/2D Imager: Decodes standard barcodes, QR codes, and DataMatrix from a single scan engine — no need to source separate scanners for 1D-only workflows that later expand to 2D. In distribution and receiving applications, this covers GS1 DataBar, PDF417 shipping labels, and consumer QR codes from a single SKU.
- Bluetooth 5.2 Radio: BT 5.2 delivers lower latency and better coexistence in RF-dense warehouses compared to BT 4.x — relevant when dozens of devices operate in the same airspace. Stable connections to paired host devices mean fewer dropped scans mid-pick-cycle.
- 735 mAh Battery: At 735 mAh, the battery is designed to carry a full shift. The available 4-slot charging cradle (CRD-RS51-4SCHG-01) and 8-slot spare battery charger (SAC-RS51-8SCHG-01) both support hot-swap rotation so a discharged battery never becomes a floor stoppage.
- Single Trigger Design: The RS51C0-LESNWR ships with a single-sided trigger assembly. This is the correct configuration for single-hand-dominant workers. If your team includes both left- and right-handed operators scanning at the same station, the double-sided trigger assembly (SG-RS51-TRGDS-01) is a field-swappable upgrade.
- 6 ft / 1.8 m Drop Specification: Rated to survive drops onto concrete from 6 ft — the height of an average adult worker dropping the device from shoulder or head level. In high-velocity pick environments where accidental drops are a daily reality, this rating directly affects repair and replacement costs.
- Compact and Lightweight — 2.47 oz: At under 2.5 oz, the scanner adds negligible weight to a gloved hand. Over a full shift, wearable scanner fatigue compounds; the RS5100's form factor is designed to stay unobtrusive through thousands of scan cycles.
- Modular Trigger Assembly: Trigger assemblies are field-replaceable — a meaningful maintenance cost control for high-throughput deployments. Replacing a worn trigger is a parts swap, not a depot repair.
Integration and Compatibility
The RS51C0-LESNWR is designed to pair with compatible Zebra mobile computers and wearable devices via Bluetooth 5.2. Zebra's 123Scan and Device Tracker utilities support remote configuration and monitoring for fleet deployments. The SE4710 scan engine reads all major 1D and 2D symbologies, making it compatible with standard WMS barcode schemas without custom decoder configuration. For multi-device operations, the available RS5100 accessory ecosystem — including the 20-slot charging cradle (CRD-RS51-20SCHG-01) — supports large fleet staging and overnight charging without manual battery management. When deploying across a Zebra mobile computing fleet, the BT 5.2 radio ensures the RS5100 fits within Zebra's broader pairing and MDM management stack.
RS51C0-LESNWR (often searched as RS51C0 LESNWR) is the single-trigger variant with the SE4710 extended-range imager and 735 mAh battery — confirm this SKU before ordering if your site requires double-sided trigger or a different scan engine configuration.
Frequently Asked Questions
Q: What devices does the RS51C0-LESNWR pair with?
A: The RS51C0-LESNWR pairs via Bluetooth 5.2 with compatible Zebra mobile computers and wearable devices, including Android-based Zebra handhelds and wrist-worn hosts that support the RS5100 series.
Q: What barcodes can the RS51C0-LESNWR read?
A: The SE4710 imager in the RS51C0-LESNWR reads both 1D and 2D symbologies — including standard linear codes, QR codes, DataMatrix, PDF417, and GS1 formats — from a single scan engine with no configuration changes required between barcode types.
Q: Can the trigger assembly be changed in the field?
A: Yes. The RS51C0-LESNWR ships with a single-sided trigger. Zebra offers a separate single-sided (SG-RS51-TRGSS-03) and double-sided trigger assembly (SG-RS51-TRGDS-01) that are field-swappable, allowing reconfiguration without depot service.
Q: How long does the battery last, and can it be hot-swapped?
A: The 735 mAh lithium-ion battery (BTRY-RS51-7MA-01) is rated for a full shift. It is user-replaceable. Using the 8-slot spare battery charger (SAC-RS51-8SCHG-01) alongside the main charging cradle, teams can rotate pre-charged batteries to maintain uptime across multi-shift operations.
Q: What is the drop rating for the RS51C0-LESNWR?
A: The RS51C0-LESNWR is rated to survive drops to concrete from 6 ft (1.8 m), which corresponds to a full overhead drop from a standing worker — a real-world reliability benchmark for high-throughput picking and receiving environments.
Q: Does the RS51C0-LESNWR require a separate power supply?
A: No. The scanner operates from its onboard 735 mAh battery and charges via the compatible Zebra RS5100 charging cradles (4-slot or 20-slot). No separate power brick or cable connects to the ring scanner during use.
The RS51C0-LESNWR hits a practical sweet spot for wearable scanning deployments: the SE4710 imager handles the full 1D/2D barcode set your WMS will throw at it, BT 5.2 holds a stable connection even in RF-noisy DCs, and at 2.47 oz the device stays out of a worker's way for an entire shift. I've seen ring scanner programs fail not because of the hardware but because the battery management plan was an afterthought — the RS5100 accessory ecosystem addresses this directly with the 8-slot spare battery charger and multi-slot cradles designed for fleet rotation.
Technical Highlights:
- SE4710 1D/2D Imager: Reads the full symbology range needed for modern WMS and receiving workflows — linear, stacked, and 2D — without requiring separate scan engine SKUs for different label types across your facility.
- Bluetooth 5.2: Lower latency and improved multi-device coexistence versus BT 4.x is a meaningful reliability gain when 50+ paired devices share the same warehouse airspace during peak shifts.
- 6 ft / 1.8 m Concrete Drop Rating: Concrete drop spec at standing adult height means this scanner handles the most common accidental drop scenario on a distribution floor without triggering an RMA cycle — a direct impact on operational uptime and total cost of ownership.
Deployment Considerations:
- The RS51C0-LESNWR ships single-trigger only — if your workforce is mixed-handedness and all workers scan at the same stations, order the double-sided trigger assembly (SG-RS51-TRGDS-01) separately or plan for per-worker configuration before rollout.
- Battery capacity is 735 mAh; for multi-shift or extended operations without a charging break, pre-staging spare batteries via the SAC-RS51-8SCHG-01 is necessary — plan your fleet's battery-to-device ratio before go-live, not after.
The RS51C0-LESNWR is the right fit for high-velocity order fulfillment and put-wall operations at distribution centers where hands-free scanning directly drives pick rates — particularly when the host device is already a Zebra Android mobile computer and Bluetooth coexistence management is already in scope.
