Measuring conditions
•
Bar code: KEYENCE standard bar code
•
Reading distance: 230 mm (BL-700/701)
380 mm (BL-740/741)
500 mm (BL-780/781)
Note: The skew angle of -20° to -5° is the specular reflection range. In this range,
bar codes cannot be read, or reading error may occur. Be sure not to mount the
BL-700 series at the above skew angles.
