Installation
The AR1000 sensor is typically installed by affixing the sensor to a machined bracket with bolts
through the four mounting holes in the sensor. Their location is shown in the mechanical drawing
above. The laser should be aimed at a target such that the distance from the reference point to the
target can be meausured.
LENS
Laser strikes distant target and
measures the distance based on
the laser reflection returned to
the collection lens.

Laser Safety
Caution: This laser device should not be aimed at the human eye. Installers of laser sensors
should follow precautions set forth by ANSI Z136.1 Standard for the Safe Use of Lasers or by
their local safety oversight organization. The AR1000 is a class 2 laser product as stipulated in
IEC 60825-1/DIN EN 60825-1:2001-11 and a class II product under FDA 21CFR. In the event of
accidental, short time laser exposure, the human eye is sufficiently protected by its own aversion
response (blinking). This natural reflex may be impaired by medication, alcohol and drugs.
Although the product can be operated without taking special safety precautions, refrain from
directly looking into the laser beam. Do not direct the laser beam at other people to avoid
potential eye hazards.

The laser safety classification reflects worst case situations. User settings or maintenance cannot
increase the level of laser radiation. Do not attempt to loosen any screws or open the sensor
housing.
