E3MC Color Sensor (LED Type)

Easy-to-see Double Indication

Conformity with the registered colors can be monitored at eight levels. (Detection level indicators). It allows fine adjustments between fine or rough discrimination while monitoring the measured results. (Threshold level indicators)

Stable and Powerful Detection for Inline Use

Stable detection is assured with a threshold of ±10 mm for built-in amplifier type and ±4mm for optical fiber type. Fiber type and Stable detection  is ±4 mm. It also provides stable and powerful detection for inline use and easy mounting function.

Highly Resistant to Changes in Sensing Object Brightness and Ambient Temperature

OMRON's unique Free Angle Optics (FAO: multi-layer polarized filter) is highly resistant to changes in the tint or brightness of sensing objects. Capable of discriminating over 90 different colors. Wide temperature range from -20^oC to 55^oC and excellent detection stability.

Maintenance-free LED Light Source

Incorporates RGB LED light sources with a long service life more than several tens of thousand hours. Greatly saves maintenance cost and ensures high performance (Halogen lamps used as light sources must be replaced or re-adjusted every nine months or so.)

Long-distance Sensing with Built-in Amplifier Type

Built-in amplifier type with a sensing distance of 60±10 mm is available for a wide range of color discriminating applications.

Principle of Detection

The E3MC detects colors by making use of the fact that the reflection ratio of a primary color (i.e. red, green or blue) reflected by an object varies with the chromatically of the object. By using a high-technology, multi-layer polarized filter called FAO (free angle optics), the E3MC emits red, green and blue light on a single optical axis. The E3MC receives the light reflected by the sensing objects through the receiver and processes the red-green-blue ratio of the light to discriminate the color of the sensing object.
