5.1.2 Mounting angle and distance
The BL-600 Series must be installed so that the laser beam is applied at an angle
of approximately 15
° with reference to a line perpendicular to the target. This
means that the BL-600/601/600HA/601HA must be tilted at an angle of 15 °. Since
the BL-650HA/651HA emits a laser beam at an angle of 17 °, tilting the unit is
unnecessary.
Refer to the read range and angle characteristics on pages 148 to 150 for the
appropriate mounting angle and distance for the BL-600 Series.
Normally, the BL-600 Series provides the best reading stability when mounted at
the following angle and distance.
BL-600/601/600HA/601HA BL-650HA/651HA
* The supplied mounting bracket facilitates the angle setting. ( ➮ See pages 75 to 78.)
* The reading rate check mode ( ➮ See pages 94 to 96.) ensures an optimal reading
position.
* The laser beam application angle for the BL-650HA/651HA is 17 ° ±3° with
reference to a line perpendicular to the rear surface of the unit.
Note 1: Do not mount the BL-600 Series so that the laser beam is applied to bar
codes at a right angle (
±10°). Otherwise, the specular reflections may cause
unstable reading or reading errors. ( ➮ See page 151.)

Note 2: The reading distance and angle may vary depending on the narrow bar
width, size, and printing quality of bar codes. Be sure to test the BL-600 Series’
ability to read the actual bar codes using “Reading rate check mode” on pages 94
to 96.
