Available. The Keyence BL-651HA is an ultra-compact laser barcode reader designed for high-resolution scanning with a side raster scanning method. It is part of the BL-600 series, known for their small form factor and precision. This model utilizes a visible red semiconductor laser with a wavelength of 655 nm, classified as a Class 2 laser product under both JIS and IEC standards. The reader offers a scanning distance of 45 to 175 mm, depending on the narrowest bar width, and can read bar widths ranging from 0.125 to 1.0 mm, with a maximum label width of 170 mm at a reading distance of 155 mm. It supports various barcode types, including CODE39, ITF, Industrial 2 of 5, COOP 2 of 5, NW-7, CODE128, EAN-128, CODE93, and JAN/EAN/UPC (A・E). The device operates within an ambient temperature range of 0 to +45 °C and is resistant to vibrations ranging from 10 to 55 Hz with a double amplitude of 1.5 mm for 2 hours in each of the X, Y, and Z directions. The BL-651HA is suitable for applications requiring precise and compact barcode scanning solutions.
