2. Mounting the CS64A
In general, the sensing area should be as dark as possible (especially if small differences
in color are to be detected). Any light that is in the sensing area that is not generated by
the CS64A is a source of error. The Blue and Green colors are more sensitive to
extraneous light than are the Red and NIR colors since these LEDs are less intense.
Small amounts of constant light can sometimes be tolerated, but bright pulsing lights
(such as fluorescent) and sunlight should never be allowed to shine into the sensing area.
Direct sunlight can also cause overheating (or damage if it shines through the lens).
The CS64A-00 should be mounted such that the bottom is 1.75 to 2 inches from the
average target object position. The sensing range will be +-1/2 inch allowing for sensor
to object movement. (See
Specifications for standoff
and range for other models).
The CS64A’s lighting system
is much more intense than it
appears because of the low
duty cycle of its light emitting
diodes (LEDs). However, in
most applications it is
desirable to keep extraneous
light out of the sensing area.
This area includes not only
the area that is directly read
by the sensor (0.35” square
for the CS64A-00), but also
the immediate surrounding
surfaces since light will
reflect into the direct sensing
area. The optimum type of
light block depends on the
application and the
environment.
If it is possible that the
CS64A could be bumped hard
enough to cause damage, it
should be mounted such that
it is protected. To minimize
electrical noise, the CS64A
enclosure should be
grounded.
If the sensor is used in a wet
or corrosive area, order the
OEM package. This package
allows the CS64A to be
mounted inside a NEMA 4X
enclosure. For convenience, a window kit is also available.
