2. Introduction
The CS24D color sensor can sort up to fifteen different colors
by comparing against Teach values. The CS24D is well suited
for on-line color sensing applications, including:
• Distinguish between objects to ensure the correct color object
is being processed on automated production lines, such as vehicle
headliners, door and body panels, and seats
• Sort objects by color – into as many as fifteen categories
• Detect presence of metal coatings or wood varnish
• Detect paint marks where bar coding is impractical
The CS24D is available in several models with nominal standoff distances of 0.75 or 1.75 inches and
several sensing area sizes. The large sensing area, good tolerance for sensor-to-target distance variation,
and diffuse lighting of these sensors improve performance on textured materials and other challenging
applications. And the CS24D’s unique eight-reading Teach Mode allows more accurate teaching and
sorting.
The CS24D will operate satisfactorily in many applications with the default settings, and may be
optimized quickly and easily using Delta’s ColorSense software (included with the CS24D color sensors).
The ColorSense program, which runs on a PC and communicates to the CS24D via RS232, can be used to
Teach the CS24D, optimize sorting
parameters for a given set of Teach values,
adjust parameters and set options.
The convenient Setup Wizard quickly
guides the user through Teaching and
setting parameters.
The Sort Editor screen allows the Teach
data to be viewed, uploaded from or
downloaded to the sensor, and saved and
retrieved from a file. The Analyze screen
shows the detailed performance of the
sensor for the Sort data and provides for
additional optimization.
Teaching the CS24D can be accomplished
via discrete inputs as well as the
ColorSense program.

and intuitive
After teaching, the CS24D indicates the detected color by turning on one or more of the four discrete
outputs in a binary coded sequence. If four or less colors are needed, the outputs can be used directly by
teaching Sort Outputs 1, 2, 4, and 8.
The CS24D has two connectors; one containing the Teach inputs and ColorSense serial port and the other
handling the outputs and power input. The connectors are environmental din-style. The standard cables
for the CS24D are ten feet long with straight connectors and pigtails. Other cable options are available—
