E3MC-Y41

RGB Color Sensor RGB LED One-output and four-output models are available Refined Performance and Easy Operation Easy-to-see Double Indication ■ Conformity with the registered colors can be monitored at eight levels. (Detection level indicators) ■ Allows adjustments between fine or rough discrimination while monitoring the measured results. Stable and Powerful Detection for Inline Use ■ Stable detection is assured with a threshold of ±10 mm for built-in amplifier type and ±4 mm for optical fiber type. 60 mm Sensing surface 10 mm 10 mm 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. Highly Resistant to Changes in Sensing Object Brightness and Ambient Temperature. ■ OMRON's unique Free Angle Optics (FAO: multi-layer polarized filter) ensure stable detection performance and 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¡C to 55¡C 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, thus greatly saving maintenance cost and ensuring high performance. (On the other hand, halogen lamps used as light sources need to be replaced or re-adjusted every nine months or so.) Discriminating Delicate Color Differences The detection level indicators are lit according to the degree of conformity between registered and detected colors. Delicate color differences are discriminated by setting the threshold to an upper level. (Fine discrimination is expected.) Sensor errors that may be caused by minor tint differences or dirt retention are prevented by setting the threshold to a lower level. (Rough discrimination is expected.) Fine discrimination Rough discrimination Detection level indicators Threshold value Output Principles 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 chromaticity of the object. By using a high-tech, multi-layer polarized filter called FAO (free angle optics), the E3MC emits red, green, and blue light on a single optical axis so that the light will be reflected by sensing objects. 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. In Mode C (Refer to the E3MC Datasheet) Photodiode Receiver lens FAO (Blue: Reflected; Red/Green: Passed) FAO (Green: Reflected; Red: Passed) Sensing object Red LED (R) Green LED (G) Blue LED (B) Emitter lens Time-sharing lighting Monitor photodiode (see note) Note: The monitor photodiode compensates LED output deviation that may be caused by a temperature change. Type Model Built-in Amplifier Type E3MC-A11 Appearance Sensing distance 0 50 100 Spot diameter No. of output Out-put 12 mm 1 E3MC-A41 PNP 4 E3MC-MA11 E3MC-MA41 E3MC-X11 0 50 100 3 mm Analog 1 NPN PNP 4 E3MC-MX11 E3MC-X81 GeneralPurpose Optical Fiber Type 3 E3MC-X41 E3MC-MX41 E3MC-Y11 NPN PNP 60±10 mm (See note 1) E3MC-A81 Optical Fiber Type NPN The shape of the amplifier section is the same as for the E3MC-A .

Eleven colors are discriminated at this distance. For a typical example, nine colors are discriminated at a sensing distance or 12 mm. Built-in Amplifier Type Optical Fiber Type General-purpose Optical Fiber Type Detection of a Mixture of Different Detection of Hard-to-discriminate Marks Color Parts (Yellow Marks on a White Background, etc.) Color Discrimination and Sorting of Bottles Using a Through-beam Optical Fiber Type (E32-T17L) Detects caps of different colors in a bottling process. Easy-to-change settings using the 4-color registration/bank selection. Highly resistant to up and down fluctuation of sensing objects and offers stable detection of marks with delicate color differences such as yellow marks on a white background. Discriminates bottles or transparent films by their color. Extraction and Sorting by Color Detection of Directional Alignment for Packing Detection of Small Marks Using a Reflective Optical Fiber Type (E32-CC200) Sorts toothbrushes by the color of their handles. Stable detection can be obtained without being influenced by changes in brightness of sensing objects. Used for aligning directions for packaging by detecting delicate color differences or very fine marks. Suited for applications where working space is so limited that the E3MC-X cannot be used. The product has been produced at OMRON Ayabe which obtained ISO9001-approval for its quality system and ISO14001-approval for its environmental management system from international certification bodies.
