Zebra DS3678-HD | Ultra-Rugged Cordless 2D Barcode Scanner | High Density | Bluetooth 4.0 | USB Kit (Scanner + Cradle + Cable Incl.)
The Zebra DS3678-HD is an ultra-rugged cordless 2D barcode scanner built specifically for high-density barcode applications. With a High Density imager, IP65/IP68 dual sealing, and a 2.4 m drop specification, it delivers fast and accurate decoding of even the smallest and most tightly-packed barcodes — without a cable holding you back.
The HD imager uses a 1,280 × 960 pixel sensor to capture fine-pitch, high-resolution barcodes found on electronics components, circuit boards, pharmaceutical labels, and compact retail packaging — codes that standard imagers routinely fail to decode.
Rated IP65 for dust and high-pressure water jets, and IP68 for submersion — the DS3678-HD exceeds the sealing of most ultra-rugged scanners. Whether it's coolant splash on a production line or a rinse-down in a food facility, it keeps scanning.
Survives repeated drops to concrete from 2.4 m — tested at temperatures from -20°C to 50°C. At 411 g it's built for all-day use in demanding environments, with a grip designed for gloved hands.
Connects wirelessly via Bluetooth 4.0 (Classic + LE) with up to 100 m line-of-sight range. This USB kit includes the DS3678-HD scanner, STB3678 single-slot cradle, and USB cable — ready to deploy out of the box.

Frequently Asked Questions
The HD (High Density) imager uses a higher-resolution 1,280 × 960 pixel sensor optimised for tiny, fine-pitch barcodes — such as those on PCBs, pharmaceutical packaging, or miniature component labels. The SR is a standard-range general-purpose imager; the HP is optimised for long-range and difficult barcodes but not specifically for high-density formats.
Yes — it carries dual sealing ratings. IP65 covers dust and high-pressure water jet resistance; IP68 covers continuous submersion. This makes it suitable for both outdoor and washdown environments.
Yes. The USB kit (SKU ending in 3U42) includes the DS3678-HD scanner, STB3678 single-slot cradle, and USB cable. No additional accessories are needed for USB deployment.
It will work, but the HD variant is optimised for small, dense barcodes. For general warehouse or logistics use where barcodes are standard size, the DS3678-SR or DS3678-HP may be a better fit.
