Modern industrial automation places increasingly higher demands on visual quality control. In industries such as automotive, electronics or packaging production, it is no longer enough to distinguish basic colors - color nuances that influence the aesthetics and perception of the product also count.
These needs are met by color sensors True Color by Micro-Epsilon, available from WObit - a Polish distributor of advanced measurement systems.
Precise color recognition technology
Sensors from the Micro-Epsilon colorSENSOR CFO series analyze the light reflected from the object's surface and compare it with previously saved color patterns. Thanks to the True Color technology, it is possible to faithfully reproduce the perception of the human eye and precisely distinguish even very similar shades.
The colorSENSOR CFO250 model is distinguished by the use of a modern color spaceLCh (Lightness, Chroma, hue angle)which better describes the actual differences in brightness and color saturation. This solution allows you to obtain extremely accurate color measurements also on metallic and shiny surfaces, where traditional methods often fail.
Recognizing color nuances of automotive controls
When producing and installingshiny metal vehicle controls – e.g. buttons, panels and switches – it is necessary to distinguish even the slightest shades of silver or chrome. Variations in coatings, minor changes in texture or light reflections may cause visual differences that affect the final aesthetic effect of the car interior.
In such processes, Micro-Epsilon colorSENSOR CFO250 color sensors are used, which:
detect subtle color differences between similar materials,
analyze coatings and surface structures,
compensate for reflections and curvatures, ensuring reliable measurements.
Additionally, themulti-teachfunction allows learning up to320 colors in 254 groupswhich makes it much easier to configure the sensor for a wide range of components. In the assembly control process, the device cooperates with the CFS4‑K18 and V14 reflective sensors, ensuring verification of the correct installation of e.g. gear change elements or control panels.
New LCh color space – a higher measurement standard
The introduction of theLChcolor space by Micro-Epsilon is a significant improvement in the context of standardizing color measurements in the automotive industry. This space describes color in three variables:
L (Lightness) – brightness,
C (Chroma) – saturation,
h (hue angle) – hue.
This color description is more consistent with human perception and the requirements of OEM manufacturers, which translates into repeatability of results and better compliance with standards used in the automotive industry.
High efficiency and intuitive operation
The Micro-Epsilon colorSENSOR CFO250 sensor, available in the WObit offer, combines high precision with impressive measurement speed. The device can evaluate up to7,500 parts per secondand the data is transmitted to the process controller at30 kHzfrequency. The intuitive web interface enables quick parameter configuration and simplified calibration - without the need to install additional software.
