Rockwell Automation 45BRD Analog Laser Sensor - Manual (Page 2)

2
The Installation Instructions should be read and understood before
operating the sensor.
The 45BRD sensor should only be installed by qualified personnel.
The 45BRD is not a safety component as described by EU machine
directives.
The 45BRD is a Class 2 laser product. There is a natural eye
aversion when looking into the laser beam. Do not look directly
into the laser beam or suppress the reflex to close your eyes.
The 45BRD should be mounted such that it is not directed at
people (head height) and the beam path is terminated at the end of
its functional path.
The laser safety label on the 45BRD sensor should be visible after
installation. A second label has been provided in the event that the
attached label is covered due to the installation.

Sensor Alignment
Position the 45BRD sensor so that the distance from the object to
the sensor will be within the sensing range of the sensor.
The sensor should be mounted at an angle of approximately 5° for
very reflective targets as shown in Figure 1.
Figure 1
The sensor should be mounted perpendicular to the direction of
travel for targets which have steps, border lines, and round targets.
See Figure 2 below.
Figure 2
The sensor will provide more precision when the spot size is not
larger than the feature that is being measured (see Figure 3).
