MT84G 2D Mini Scan Engine

Ideal for Space-Constrained Applications

OEM Barcode Scan Engines MT84G is an extremely miniaturized 2D scan engine that is designed "Smallest in the world" to fit into the most space-constrained applications including mobile devices, wearable devices, and smartphones. With 3.3V low voltage power supply and power consumption of a few micro amps during sleep mode, the MT84G barcode scan engines is also ideal for host devices with limited battery.

Reliable and Flexible Operations

With golden fingers for connection, the MT84G scan engines can be firmly mounted on the host PCB with soldering, which not only increases mechanical reliability but reduces the cost and risk incurred in installing flex cable and connector. The flash memory of MT84G serves as a flexible and upgradeable provision for additional requirements or performance enhancement and extends the product's lifecycle as well.

Ambient Light Immunity

MT84G scan engines automatically adjusts its parameters for optimal scanning performance which provides the freedom to scan barcodes from under complete darkness to direct sunlight. With configurable scan rate between auto-adaptive mode and fixed mode, MT84G is ideal for mobile applications and smart devices which require more ambient light immunity.

Useful Demo Kit

MB100 Demo Kit (sold separately) provides the software and hardware tools required for testing MT84G before integrating it into the host device. The kit contains software utility, interface cables, and MB100 Multi I/O board. Due to its small size, MB100 is also suitable for being installed inside the host system as an interface board connecting the MT84G scan engine to the host device.
