NETUM NT-EM61 Embedded 1D/2D Barcode Scanner Module � Multi-Interface (USB/TTL / RS232 / RS485) Industrial-Grade Compact Fixed Barcode Reader
The NETUM NT-EM61 Embedded Scanning Engine is a high-performance barcode
scanner module specifically designed for embedded systems such as kiosks,
vending machines, smart lockers, and industrial control equipment. It supports
a wide range of 1D and 2D barcode formats (including EAN, UPC, Code128, QR
Code, DataMatrix, and PDF417). With multiple interface options�USB HID/USB
COM, TTL, and customizable RS232/RS485�the NT-EM61 offers excellent
compatibility and flexibility for different integration scenarios. Built with
industrial-grade standards, it operates reliably under -20�C to +60�C, and
passes rigorous tests for vibration, impact, and thermal shock.Its compact
form factor (77.8 � 66.4 � 44.7 mm) and light weight (about 70 g) make it
ideal for space-constrained devices. The scanner delivers fast and accurate
barcode recognition, even for motion or low-contrast codes, ensuring smooth
performance in demanding environments.With wide voltage input (5V�16V
customizable) and stable performance, the NT-EM61 is perfectly suited for
retail, finance, logistics, and industrial automation
applications.Specification1.Scanning Performance Image Sensor: 640 x 480 CMOS
