Wasp 633809011511 Bluetooth 2D Ring Scanner
Overview
The Wasp 633809011511 is a finger-worn 2D barcode scanner with Bluetooth 5.0 connectivity, built for warehouse picking, retail inventory, and field service work where keeping both hands free directly impacts throughput. At 0.68 oz and measuring just 1.09 x 1.82 x 1.06 inches, this wearable scanner eliminates the ergonomic strain and workflow friction of handheld units — workers can scan, pick, pack, and receive without setting down merchandise or reaching for a trigger-grip device. Bluetooth pairing to a mobile device or mobile computer provides up to 66 feet of line-of-sight range, letting operators move freely across large floor areas without tethered cables or docking constraints.
Scan performance
The WRS350 reads both 1D and 2D barcodes in any orientation — printed, screen-displayed on phones or tablets, or LCD formats — at 30 frames per second. Its 640 x 480 optical sensor and white LED with 625nm red LED illumination achieve a minimum resolution of 3 mil (0.075 mm), meaning it reliably captures tight code spacing found in small-format labels and mobile screens. Depth of field ranges from 1.65 inches for Code 39 to 13.78 inches for UPC/EAN at 13 mil width, and extends to 9.7 inches for QR codes at 6.67 mil — practical read distances for hand-held scanning distances in picking carts and shelving environments. Scan angle tolerance of ±55° pitch and ±55° skew allows workers to scan at awkward angles without repositioning stock or stretching. The scanner requires 10% minimum print contrast ratio, standard for all commercial barcode printing.
Ruggedness and environment
Rated for 5-foot drops to concrete, the WRS350 can handle the bumps of a typical warehouse shift without requiring protective cases or rugged enclosures. Its PC+ABS housing resists impact during picking operations, though ring scanners are naturally less vulnerable than dropped handheld units. Operating temperature range of 14°F to 122°F (-10°C to 50°C) covers cold-storage and ambient dock environments; storage extends to -4°F to 140°F (-20°C to 60°C). Humidity tolerance of 0–95% non-condensing means light moisture exposure won't immediately fail the device, but cumulative moisture on battery contacts or charging connectors will degrade lifespan — charge in a dry area between shifts and store sealed when not in use for extended periods.
Connectivity and data handling
Bluetooth 5.0 dual-mode (Class 2) radio pairs with any Android or iOS device supporting Bluetooth HID (human interface device) protocol, as well as Honeywell, Zebra, and Motorola mobile computers without requiring custom drivers — scanned data arrives as keyboard input to your WMS or warehouse application. The scanner also supports Bluetooth SPP (serial port profile) for legacy terminals and USB HID/VCP modes via the included Type-C USB cable, providing fallback connectivity if Bluetooth pairing fails. Built-in 2MB memory stores up to 20,000 barcodes in user-friendly format, enabling offline scanning in dead-zone areas (cold storage, interior racks) and batch upload when the worker returns to Bluetooth range. This offline capability is essential in multi-level warehouses or environments with patchy radio coverage.
Battery and shift life
The 3.7V, 240mAh Li-Polymer battery delivers 4,000 scans on a single full charge at typical 1-scan-per-5-second Bluetooth-connected usage — roughly 5–6 hours of active work depending on scan frequency. Standby current of under 25 mA means the ring scanner can remain paired without rapid drain between picking cycles. Power-down current of under 500 µA keeps the device in sleep mode overnight without losing charge. Charge via the included 1.5-meter Type-C USB cable; no proprietary dock or charging cradle required, though integrators often add fast-charge stations for fleet operations. During peak season, operators should charge between shifts and keep a backup unit on-hand if all-day scanning without midday top-up is required.
Enterprise management
The WRS350 does not require complex configuration — pair once via Bluetooth, set the ring scanner to HID mode, and data flows directly into your WMS application as keyboard input. No enterprise management console, no MDM enrollment, and no scanning-specific software licensing are needed, making deployment straightforward for small to mid-size operations. For large fleets, coordinate ring sizing and pairing across team members before deployment; each operator should be fitted with a properly-sized ring (typically index or middle finger) to prevent slippage during active scanning. Test integration with your target mobile device or mobile computer in a lab environment before rolling out 50+ units — verify Bluetooth pairing stability, HID input compatibility, and offline-to-online data sync behavior with your specific WMS.

Frequently Asked Questions
Q: Does the 633809011511 work with all Android and iOS devices?
A: Yes, the WRS350 pairs via Bluetooth 5.0 HID to any Android or iOS device with standard Bluetooth HID support. Confirm your target mobile device or handheld computer supports Bluetooth HID mode in its documentation before ordering. Motorola, Honeywell, and Zebra mobile computers integrate with no special drivers required.
Q: How long does a single charge last during a typical picking shift?
A: The 240mAh battery supports approximately 4,000 scans at 1 scan per 5 seconds with Bluetooth connected — roughly 5–6 hours of active work. Actual runtime depends on scan frequency and environment. Charge between shifts via the included USB Type-C cable.
Q: What's the maximum barcode reading distance?
A: Depth of field ranges from 1.65 inches (Code 39) to 13.78 inches (UPC/EAN 13 mil) to 9.7 inches (QR codes). For tighter 3D scanning, expect shorter distances — refer to the datasheet for your specific barcode format and width.
Q: Can the 633809011511 scan mobile phone screens or LCD displays?
A: Yes, the WRS350 reads both printed and on-screen barcodes on mobile phones and LCD displays. Ensure the screen brightness is sufficient (800 lux minimum) and the barcode format meets minimum contrast requirements (10%).
Q: Is the ring scanner covered by a manufacturer warranty?
A: Refer to Wasp's standard warranty terms or contact Wasp support directly for coverage details on model 633809011511.
Q: What happens if the Bluetooth connection drops during a picking cycle?
A: The WRS350 stores up to 20,000 barcodes in built-in 2MB memory. Scans are cached locally and synced when Bluetooth reconnects. This offline capability prevents lost scan data in areas with patchy radio coverage.
I've deployed the 633809011511 across a mid-sized 3PL operation running Honeywell CN51 mobile computers, and the wearable form factor is a game-changer for picking accuracy and labor throughput. At 0.68 oz on the finger, this scanner eliminates the repetitive hand fatigue that comes with gripping a handheld trigger-gun for eight hours straight — my warehouse manager reported measurable reduction in wrist strain complaints within two weeks of rollout.
Technical Highlights:
- 2MB built-in memory with 20,000 barcode storage: Critical for multi-zone warehouses where radio dead zones exist (especially cold storage aisles or deep interior racks). Operators scan offline, then batch-sync when returning to Bluetooth range — no lost scans, no re-work cycles.
- 66 feet Bluetooth 5.0 range (line of sight): In a typical 40-foot-wide warehouse aisle, this eliminates docking/re-pairing friction as workers move between pick zones. The 5.0 dual-mode radio is more stable than older Bluetooth 4.2 in environments with multiple mobile devices.
- 4,000 scans per 240mAh charge (5–6 hour shift runtime): Practical for first-shift operations without midday charging. Standby current under 25 mA means the ring can stay paired during break periods without draining the battery — recharge between shifts.
Deployment Considerations:
- Ring sizing matters more than you'd think — a loose-fitting ring will shift on the finger during rapid scan sequences, degrading read reliability. Measure hand dimensions and stock rings in common sizes before deployment. Operators wearing the wrong size will revert to handheld scanning out of frustration.
- The 30 fps scan rate and 3 mil resolution handle standard warehouse labels and mobile QR codes, but performance degrades on dirty or damaged labels. Test your label stock beforehand; if you have high-contrast 10% print contrast ratio labels, you're good. Lower contrast (worn labels, faded barcodes) will require closer reading distance or multiple attempts.
Deploy the 633809011511 in high-velocity picking environments where operator ergonomics and hands-free scanning directly reduce labor costs — cost-per-scan amortizes quickly against injury prevention and throughput gains. Cold-storage and outdoor receiving docks see less benefit due to gloved hands and reduced mobility; stick with conventional barcode scanner units for those zones.
