A Self-Contained, Easy-To-Use Scanning/Lighting System in a
Compact Package For Production Line Automation Applications
The CS2 Color Scanner analyzes
reflected light captured by a silicon
cell.
It determines color by turning on only
the desired color at a given time using
its patented, solid-state lighting
system.
The CS2 then activates data outputs
based on the relative magnitude of the
Base color and the ratio of the Base
color and the Sense color.
Primary features
• Fast response rate: 500
microseconds, 50 uS optional.
• 100,000 hour life LED lighting
system
• Automatic adjustment to changing
ambient
• Optically isolated outputs for Base
limit and Ratio limit. Analog
outputs for Base and Sense colors
• Easy set-up using integrated bar
graph display
• Compact size: 6 x 6.4 x 1.25"
• Low power requirements: 24Vdc @
250 mA maximum
• Color range options: blue to near-
infrared
• Versatility: Other options include
optimizing computer interface. Use
with rotary pulse generator to check
product or defect length, too.

Use the CS2 Color Scanner to:
• Sort objects and compare
peeled vs. unpeeled
organic vs. non-organic
ripe vs. green
over-ripe/rotten vs. normal
• Detect product defects such as
stains
spills
knots
over or undercooked product
• Align
materials
labels
packages
• Read paint markings
where bar coding or inkjet
printing is impractical or
impossible
The CS2 detects deviations from
normal or average color, based on the
Sense/Base ratio.
It can be configured to detect either a
high or low ratio. whether that's a
feature needed to be recognized or a
product defect.
Using the narrow-line scanning area
option, a wide area up to 1.25" can be
scanned for defects or features.
Detecting green areas on carrots, knots
on wood, and burned cookies are
applications that typically use the Low
Ratio setting. Detecting white ends on
asparagus is an example of a High
Ratio setting.

Page 5: Mounting The Cs2
Mount the CS2 so that the object to be scanned is within the scanning area. In the default configuration, the center of the scanning range is 1.75" from the bottom of the scanner. -
Page 6: Wiring
The CS2 is designed to be wired using watertight flexible plastic conduit. In applications where sealed operation is unnecessary, the wires can be run out through a strain relief connector. The conduit can also be used to pressurize the CS2 with low pressure, dry air for additional protection. - Page 7 CS2 Color Scanner Using the CS2 With a Rotary-Pulse-Encoder (RPG) for Counting Objects and Defects Defect Counter To synchronize CS2's scan with an external event, use the external Sense Threshold trigger input.

The CS2 must be done, be sure the increased distance does not allow ambient powered by a dedicated power supply, and the optional light to become a problem. - Page 13 Multiple units can be packaged into a single enclosure, resulting in a cleaner package.
