Ultra-Rugged Cordless Scanner

The Zebra DS3678-DP is a handheld, cordless barcode scanner built for direct part mark and standard 1D/2D code capture. It targets manufacturing, aerospace, and automotive operations that require traceability in punishing environments. The IP67-rated housing resists dust, spray, and water immersion. Bluetooth Class 1 connectivity provides wireless freedom across the facility.

Industrial Interface Flexibility

The cradle supports USB, RS232, Keyboard Wedge, and industrial Ethernet protocols including EtherNet/IP, Profinet, and Modbus TCP. This breadth lets the scanner integrate with legacy hosts and modern plant networks without extra gateways. Battery capacity is 3100 mAh for extended shift coverage. The scanner decodes all common 1D symbologies plus PDF417, DataMatrix, Aztec, and other 2D codes.

Direct Part Mark Optimisation

The 2D area imager uses diffuse 634 nm LED illumination and a 655 nm laser aimer to read marks created by dot peen, laser etch, and chemical etch on metal, plastic, and glass. Pitch and yaw tolerance reach ±60 degrees with full 360-degree roll freedom. Minimum print contrast requirement is 15 percent reflective difference. Not suited for buyers needing a tethered-only device or a scanner without DPM-tuned optics.

Questions about this item

Will the DS3678-DP cradle connect to my existing RS232 serial port?

Yes, the cradle supports RS232 alongside USB and Keyboard Wedge interfaces, so it can plug into a legacy serial port without an adapter.

How do I know the scanner is reading DPM codes correctly after pairing?

The scanner emits a decode beep and the cradle LED shows link status; successful reads of DataMatrix or dot-peen marks confirm the 2D imager is working.

Does the box contain everything needed for cordless USB operation, or must I buy a cable separately?

The package includes the cradle, a USB cable, power supply and line cord, so no extra cable is required for USB host power.
