The Keyence BL-700 Long-distance Laser Barcode Reader is a high-resolution scanning solution engineered for precision, speed, and flexibility in industrial and commercial applications. Built with a visible semiconductor laser (wavelength: 655 nm), this model ensures excellent readability even on barcodes with extremely narrow bars. Its capability to read bar widths down to 0.15 mm makes it an excellent choice for industries that rely on compact, high-density codes, such as electronics, medical device manufacturing, and logistics.

A key strength of the BL-700 is its scanning speed of 700 scans per second, allowing it to handle high-speed production lines or environments where fast throughput is critical. Combined with a reading distance of 160 to 370 mm, it balances accuracy with flexibility, enabling operators to capture codes reliably without needing to position the reader excessively close to the target. The optimized focal point of 230 mm ensures stable and consistent readability across a variety of working conditions. Additionally, it supports wide label formats up to 310 mm in width, further expanding its usability in different packaging and labeling setups.

The BL-700 supports a broad range of industry-standard symbologies, including widely used formats such as JAN/EAN/UPC for retail, CODE39 and CODE128 for logistics and asset tracking, and specialized codes like COOP 2 of 5 and Industrial 2 of 5 for manufacturing. With the ability to decode up to 32 digits (or 64 digits for CODE128 with start character C), it is capable of handling complex data requirements with ease. Its decoding reliability is enhanced by a minimum Print Contrast Signal (PCS) of 0.6, ensuring stable performance even under less-than-ideal label conditions, provided the white background has at least 75% reflectance.

From a safety perspective, the BL-700 employs a laser classified as Class 2, adhering to international standards such as JIS C6802, IEC 60825-1, and FDA (CDRH) guidelines. This classification ensures that it remains safe for typical operator use when handled appropriately.

In terms of system integration, the BL-700 is equipped with a robust RS-232C interface, supporting multiple baud rates ranging from 600 to 38400 bps. Its asynchronous communication mode, combined with selectable parity and stop bit options, allows for seamless adaptation to diverse system environments. The device also includes NPN open-collector outputs for OK/NG status, making it easy to interface with PLCs or external control units. Additionally, it features both voltage and non-voltage input formats, giving engineers more flexibility during installation.

In summary, the Keyence BL-700 is a reliable, high-speed, and high-resolution barcode reader designed to meet the demands of precision industries. Whether deployed in high-volume logistics hubs, automated manufacturing systems, or environments requiring consistent accuracy, it delivers robust performance while ensuring ease of integration into existing workflows.
