Metal 1D 2D Barcode Reader Module with UART Interface, 25mm Mounting Hole

The GM861 Barcode Reader Module The GM861 is a compact barcode reading module built around the GM861S platform, featuring a threaded stainless steel housing that makes installation straightforward. With a mounting hole diameter of just 25mm, it fits neatly into a wide range of equipment designs where space is at a premium. The module is finished in silver, giving it a clean and professional appearance that suits commercial and industrial settings alike. Scanning Performance and Capability Drawing on the proven scan engine from the GM80X series, the GM861 reads all common one-dimensional barcodes with ease and handles two-dimensional codes at speed. Its linear barcode scan rate is particularly strong, and it copes well with barcodes displayed on screens, which is a practical advantage in modern retail and ticketing environments. The module also incorporates an intelligent image recognition algorithm paired with an advanced decoding engine, allowing it to capture barcode symbols accurately and without fuss. This combination simplifies the development of barcode-enabled products, so you can integrate reliable scanning into your own device with minimal effort. Interface and Integration The GM861 communicates via a UART interface, making it a straightforward choice for developers working on embedded systems or custom hardware. Its threaded metal casing not only protects the internal components but also allows for quick and secure mounting, reducing assembly time during production. Whether you are building a self-service kiosk, access control terminal, or handheld device, this module offers a dependable and easy-to-integrate scanning solution.
