Zebra LI3678-SR | Ultra-Rugged Cordless Linear Imager | Bluetooth 4.0 BLE | (Scanner Only)
The Zebra LI3678-SR is a flagship ultra-rugged cordless 1D linear imager built for demanding warehouse, manufacturing, and logistics environments where 2D codes are not required and all-day scanning endurance is paramount. Part of Zebra's 3600 Ultra-Rugged Series, it combines a 1500-pixel linear scan engine with Bluetooth 4.0 BLE connectivity, delivering a 300-foot wireless range and up to 70,000 scans on a single PowerPrecision+ charge. The LI3678-SR0F003VZWW is a scanner-only configuration with vibration motor feedback — no cradle or cable is included.
Ultra-Rugged Construction — IP67 & 2.4m Drop Rating
The LI3678-SR is rated IP67 — fully sealed against dust ingress and capable of withstanding submersion in up to 1 metre of water for 30 minutes. It survives repeated 8-foot (2.4m) drops onto concrete and endures 5,000 tumble cycles, covering the most punishing warehouse and dock-door environments. The operating temperature range of -30°C to 50°C supports cold storage, freezer aisles, and outdoor receiving areas. This level of ruggedness is typical of Zebra's 3600 Series, which is purpose-built to outlast ordinary enterprise scanners by years under continuous heavy use.
Extended Standard Range Linear Scan Engine
The LI3678-SR uses a 1500-pixel linear imager with a standard reading range of 1.25 cm to 91.4 cm (0.5 in to 3 ft), covering the majority of industrial scanning applications — conveyor labels, shelf tags, and handheld item scanning at arm's length. Zebra claims 30% more working range than competing 1D linear scanners in the same class, giving operators more flexibility in approach distance without failed reads. A precision laser aiming line provides one of the sharpest targeting patterns in the category for accurate placement on densely packed labels. All major 1D symbologies are fully supported including Code 128, Code 39, Codabar, EAN-8, EAN-13, UPC-A, UPC-E, and Interleaved 2-of-5.
Bluetooth 4.0 BLE — 300 ft Wireless Range
The LI3678-SR connects wirelessly via Bluetooth 4.0 Low Energy (BLE), providing a line-of-sight range of up to 300 feet (91 metres) from the host or cradle. BLE delivers both high speed and maximum energy efficiency — the scanner maintains a responsive wireless link throughout an entire shift without sacrificing battery capacity to radio overhead. Pairing with Zebra cradles (such as the CR3678 series) is straightforward via standard Bluetooth SSP. The scanner is also compatible with Zebra mobile computers and other Bluetooth HID hosts for flexible deployment without a dedicated cradle.
PowerPrecision+ Battery — 70,000 Scans Per Charge
The LI3678-SR is powered by Zebra's PowerPrecision+ 3100 mAh Lithium-Ion battery, delivering approximately 70,000 scans per full charge — equivalent to around 56 hours of typical scanning use. Zebra states this represents 56% more scans per charge than competitive batteries. PowerPrecision+ also provides smart battery management: the battery communicates its charge level, health status, and remaining capacity in real time through the BYOD management system, allowing IT teams to proactively replace batteries approaching end-of-life before they cause operational downtime.
Triple Feedback — Vibration, LED & Beeper
The LI3678-SR0F003VZWW includes a vibration motor (the V in the SKU) in addition to red/green LEDs and an audible beeper, providing three simultaneous good-read confirmation channels. In noisy environments such as manufacturing floors where beeper tones are inaudible, and in situations where LED visibility is low, the vibration motor gives operators unambiguous tactile confirmation of every successful scan. This eliminates the need to visually confirm each read and significantly reduces the rate of missed or double-scans in high-volume workflows.

Frequently Asked Questions
Does the LI3678-SR read 2D barcodes like QR Code or Data Matrix?
No. The LI3678 is a linear imager designed exclusively for 1D barcodes. It cannot read 2D symbologies such as QR Code, Data Matrix, PDF417, or Aztec. If your operation requires 2D scanning, Zebra's DS3678-SR is the equivalent ultra-rugged model with a 2D area imager.
What cradle does the LI3678-SR0F003VZWW require?
This scanner-only SKU does not include a cradle or cables. Compatible cradles include the Zebra CR3678 series (single-slot charging and communication cradles). The CR3678-PC4S07B3WW is the standard USB cradle for this scanner. Ensure you purchase the correct cradle model for your required interface (USB, RS-232, or charge-only).
What is the difference between the LI3678-SR and DS3678-SR?
The LI3678-SR is a 1D-only linear imager; the DS3678-SR is a 2D area imager that reads both 1D and 2D symbologies. Both share the same ultra-rugged 3600 Series platform (IP67, 2.4m drop, 7,500 tumbles). Choose the LI3678-SR if your operation uses only 1D barcodes — it costs less per unit and the linear engine may offer marginally faster reads on simple 1D codes in high-throughput lines.
How long does the LI3678-SR battery last and can it be replaced in the field?
The PowerPrecision+ 3100 mAh battery delivers approximately 70,000 scans or around 56 hours of typical use per charge. The battery is user-replaceable — it can be swapped in the field without tools, and Zebra's PowerPrecision+ technology reports battery health and remaining capacity in real time to help plan proactive replacements before failures occur.
