Zebra WT6400 Wearable Computer

The Zebra WT6400 is a next-generation Android wearable computer designed to improve productivity and workflow efficiency in demanding hands-free environments such as warehouses, distribution centres and manufacturing plants. It is worn on the wrist and gives workers fast access to task information, application screens, voice functions, wireless connectivity and scanner pairing while keeping both hands free for picking, sorting, receiving, put-away, replenishment, packing and material handling. The WT6400 should be positioned as a wearable host computer, not as an integrated barcode scanner. Barcode capture is handled through compatible Zebra wearable scanners. The WT6400 supports Zebra Bluetooth wearable scanners such as the RS2100, RS5100 and RS6100 via NFC tap-to-pair, and it also supports Zebra corded wearable scanners such as the RS4000 and RS5000 through rugged side connectors. The RS5100 and RS6100 can be powered by the WT6400 using a corded adapter, while communication remains over Bluetooth. The WT6400 is built for more demanding environments than a retail-only wearable. Typical applications include warehouse picking, sorting, receiving, put-away, replenishment, packing, reverse logistics, manufacturing inventory, line-side replenishment, work-in-process material handling, tracking and tracing, quality control and safety testing. A major improvement is the larger display area. The WT6400 uses a 4.7-inch colour display with 720 × 1280 resolution, giving workers more screen space for task lists, item details, picking instructions and workflow prompts. The display is designed to reduce scrolling and make key information easier to view at a glance. The capacitive touch panel supports finger, gloved finger and conductive stylus input and is protected by Corning Gorilla Glass Victus 2. The WT6400 is available in two physical versions: Touch Only and Touch + Keypad. The Touch Only model is suited to touch-based workflows where workers rely mainly on screen interaction and paired scanners. The Touch + Keypad model adds a 23-key alphanumeric / function keypad positioned below the display. This keypad layout is designed for right- and left-handed use, and for workers using gloves. It is especially useful where physical key entry is still important in warehouse or manufacturing workflows. Ergonomics are a key part of the WT6400 design. Compared with earlier wrist-worn solutions, the WT6400 provides a larger display with only a minimal increase in overall size and weight. Its low profile and lower centre of gravity help reduce bulk and arm fatigue, while making it easier to reach into shelves, bins, racks and tighter work areas. The universal wrist mount supports multiple strap options, allowing businesses to choose the most suitable wearing style for the user and workflow. Options include cost-effective Velcro straps, a micro-adjustable single dial strap and a dual dial strap that provides a more secure and refined fit, especially when using the keypad model. A single-button release allows the device to snap on and off the wrist mount, making it easier to assign personal mounts and straps to workers for hygiene and comfort. Battery handling is designed for active work. The battery can be removed and replaced with a natural motion while the device remains on the wrist. This helps workers change batteries quickly without removing the WT6400 from the arm. The standard battery has a typical capacity of 3500 mAh and supports operation from -20°C to 50°C. The extended battery has a typical capacity of 5000 mAh and is freezer-rated for operation from -30°C to 50°C. Hot-swap support allows battery changes without powering down and helps preserve the worker’s place in the workflow. The WT6400 includes a 13 MP side camera angled at 22 degrees. This camera is designed to allow workers to capture photos while keeping the display in their natural line of sight. It can support proof of condition, proof of receipt, issue reporting, quality checks and other visual documentation workflows. The angled camera is particularly useful because workers do not need to twist the wrist or arm unnaturally to aim. Performance is based on a Qualcomm QCS4490 octa-core processor running at 2.4 GHz. The device includes 6 GB RAM and 64 GB Flash. The supplied material positions the platform for current and future enterprise applications, with Android support through Android 17 mentioned in the source material. For deployment planning, supported Android versions should still be verified against Zebra’s current Android version information. Wireless connectivity is a major strength. The WT6400 supports Wi-Fi 6E with IEEE 802.11 a/b/g/n/ac/ax, tri-band 2.4 GHz, 5 GHz and 6 GHz operation, 2x2 MU-MIMO, Dual Band Simultaneous, IPv4 and IPv6. Data rates are listed up to 2402 Mbps on 5 GHz and 6 GHz, and up to 286.8 Mbps on 2.4 GHz, depending on configuration and regulatory conditions. Zebra Mobility DNA Wireless Fusion helps keep workers connected while roaming across large facilities. Bluetooth support is Bluetooth 5.3 Class 1. NFC supports ISO 14443 Type A and B, FeliCa, ISO 15693 and NFC Forum cards 1 to 5. NFC is also important for operational simplicity because it allows workers to tap-to-pair compatible Bluetooth scanners and headsets without complicated setup steps. The WT6400 includes audible tone, multicolour LED and haptic feedback for notifications. Voice and audio features include speaker, microphone and push-to-talk voice support. The Touch Only model includes three programmable function buttons, while both versions include the power button. The WT6400 is rugged enough for demanding enterprise use. It operates from -20°C to 50°C with the standard battery and from -30°C to 50°C with the freezer-rated extended battery. Storage temperature is -40°C to 70°C. The device is sealed to IP65 and IP67 with battery according to applicable IEC sealing specifications. Drop specifications include 1.8 m to concrete at +23°C to +50°C and 1.2 m to concrete across the full -30°C to 50°C temperature range. It also supports 1,000 tumbles from 0.5 m at room temperature. Additional durability features include vibration resistance, ESD protection of ±15 kV air discharge and ±8 kV direct / indirect discharge, and Corning Gorilla Glass Victus 2 display protection. Interactive Sensor Technology includes a light sensor for automatic display brightness adjustment, a motion sensor with 3-axis accelerometer and MEMS gyro, and a magnetometer / eCompass for direction and orientation detection. Security features include FIPS 140-2, Secure Boot and Verified Boot. The WT6400 is also listed as Android Enterprise Recommended. LifeGuard for Android is available with a Zebra OneCare support contract and helps organisations control Android security updates and OS lifecycle management. The WT6400 also has sustainability-focused design elements. The supplied material states that the device is built with over 40% post-consumer recycled plastics and avoids several major environmental toxins, including mercury and PFO / PFOAs. The Corning Gorilla Glass Victus 2 display is made with 22% recycled glass. Batteries are swappable and replaceable, while battery health insights can help reduce unnecessary battery replacement. Packaging is described as 90% biodegradable and made with recycled materials. Zebra Mobility DNA tools help simplify integration, deployment, security, management and daily use. Zebra DNA Cloud can be used to deploy and manage Mobility DNA applications. Mobility DNA tools can improve device setup, security, application control, connectivity, diagnostics and device lifecycle management. Feature availability may vary by model and may require a support contract. Overall, the Zebra WT6400 is a strong choice for organisations that need a modern wrist-worn Android host computer for warehouse and manufacturing hands-free workflows. Its strongest value lies in its large 4.7-inch display, Touch Only and Touch + Keypad options, Wi-Fi 6E, rugged freezer-ready design with extended battery, 13 MP angled side camera, scanner compatibility, hot-swap battery support, Android Enterprise Recommended status and Zebra Mobility DNA ecosystem.
