A.3 Angular Characteristics (Typical)
Mount the BL-180 referring to the data given below. (The BL-185 provides the
same characteristics as the BL-180.)
(Measuring conditions)
• The KEYENCE standard bar code is used.
• Reading distance: 33 mm
The skew angles of -5° to +10° are the specular reflection range (dead angles).
In this range, bar codes cannot be read, or reading error may occur. Avoid mount-
ing the BL-180 series at the above skew angles.
Skew Pitch
Tilt
Narrow bar width Skew Pitch Tilt
0.125 to 0.19 mm(less than 0.19 mm) -40° to -5°, +10° to +40° ±15° ±10°
0.19 to 1.0 mm -40° to -5°, +10° to +40° ±15° ±15°
