colorSENSOR CFO
1.5 Proper Environment
- Protection class: IP 65
- Operating temperature: -10 °C ... +55 °C
- Storage temperature: -10 °C ... +85 °C
- Humidity:
20 - 80 % relative humidity (non-condensing)
- Ambient pressure: Atmospheric pressure
The sensor is stable and can be used in a wide temperature range. When all sockets are in use or covered
with a protective cap, the sensor can be used safely even under contaminated environmental conditions.
2. Functional Principle, Technical Data
2.1 Short Description
The colorSENSOR CFO is an optical sensor for precise color recognition in industrial applications, built into
a sturdy aluminum housing. The controller is distinguished by high color accuracy, state-of-the-art interfaces
and intuitive operation. Optical fibers, which can be adapted for various measuring tasks, are connected to
the controller. The rear of the sensor allows fixation using the dovetail principle. A coupling is available sepa-
rately for mounting on a DIN rail, see Chap.

2.2 Measuring Principle
The specimen is illuminated with homogeneous, white light from an LED. An illuminated dot is projected with
the aid of a optical fiber onto the surface to be checked. The light is reflected diffusely at a specified angle
and transmitted by the same optical fiber to a perceptive True Color Sensor (XYZ) where it is analyzed.
The three light wavelength ranges, i.e.
- X = long wave,
- Y = medium wave and
- Z = short wave frequency ranges
from the specimen are used to determine the diffuse color reflections and transformed to a selected color
space. These color values are calculated according to the procedure described in DIN 5033.
