The Keyence BL-741 Long-Distance Laser Barcode Reader is engineered to provide reliable, high-performance scanning for medium-range applications. Designed with a raster scanning method, it delivers efficient decoding of barcodes across varied surfaces and environments, ensuring that both wide and narrow codes are captured with precision. Its focal point is set at 400 mm, enabling optimal readability within a working range of 150 to 750 mm. This makes the BL-741 highly versatile, suitable for logistics, manufacturing, warehousing, and distribution systems where consistent mid-range barcode scanning is critical.

One of the standout aspects of the BL-741 is its high-speed scanning performance. With a scanning rate of 700 scans per second, it guarantees fast recognition even in applications that demand rapid throughput. The ability to read barcodes at such speeds minimizes downtime and accelerates automated processes, particularly in conveyor-based systems or production lines where efficiency is paramount. Its reliable detection of bar widths ranging from 0.25 to 2.0 mm ensures compatibility with a wide variety of label sizes, from small product markings to larger identification codes.

The BL-741 also offers extensive code compatibility, supporting a wide range of common symbologies. These include retail-standard formats such as UPC and EAN, as well as industrial standards like CODE39, ITF, and Industrial 2 of 5. It even supports advanced formats like CODE128, capable of reading up to 64 digits when using specific start characters. This breadth of compatibility ensures that a single scanner can be used across multiple workflows, reducing the need for specialized equipment.

Connectivity and integration are central to the BL-741’s design. It is equipped with an RS-232C communication interface that supports various baud rates, ranging from 600 to 38,400 bps, providing flexible integration options with different control systems. Its asynchronous communication, adjustable data lengths, parity check options, and configurable stop bits enhance compatibility with diverse automation setups. Additionally, the BL-741 features dual output terminals for OK and NG signals, using NPN open collector outputs rated for 24 VDC and 30 mA, making it ideal for integration with quality control systems that require reliable pass/fail signaling.

Safety and reliability are also key considerations. The BL-741 employs a visible semiconductor laser with a wavelength of 655 nm, classified under Class 2 laser safety standards (IEC, JIS, and FDA compliance). This ensures safe operation in industrial environments without compromising performance. With a PCS requirement of 0.6 or more and reflectance tolerance of 75% or greater for the white areas, it maintains stable reading performance even under less-than-ideal label conditions.

In summary, the Keyence BL-741 offers a powerful combination of speed, flexibility, and connectivity in a medium-range raster scanning package. Its wide code compatibility, robust I/O design, and high-speed scanning rate make it a versatile solution for applications requiring dependable mid-range barcode reading, delivering efficiency and accuracy across industrial and commercial operations.
