User manual OMRON E3MC DATASHEET

[. . . ] Color sensor (LED type) E3MC E3MC RGB Color Sensor Discriminates Delicate Differences in Color. Features Double Indication ensuring high visibilty. · Conformity with the registered colors can be monitored at eight levels. (Detection level indicators) · Allows fine adjustment between fine or rough discrimination while monitoring the measured results. · 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. Great maintenance-cost saver ensuring high performance (Halogen lamps used as light sources must be replaced or readjusted every nine months or so. ) 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. [. . . ] (For conformity output setting) Set the threshold to a higher level for highly-precise color discrimination or to a lower level to allow margins for discriminated colors (ignore minor tint differences, dirt retention or like).

The control output will turn ON if the detection level (green) exceeds the threshold level (red) and turn OFF if the detection level does not exceed the threshold level. (For conformity output setting) Set the threshold to a higher level for highly-precise color discrimination or to a lower level to allow margins for discriminated colors (ignore minor tint differences, dirt retention or like).

Registered Color Selection (Bank Selection Input) 1-output Models Only In the RUN mode, bank selection can be made externally with the bank selection input 1 (yellow) and input 2 (green). The selected bank is indicated by the bank selection indicator.

The output will hold the previous status if the input of the external synchronous input terminal is set to ON. As for the 4-output models, this function applies to the output of all the channels. Sensing object ON Discrimination OFF result ON External synchronous input Control output Output on hold OFF ON OFF This status can be on hold by an external synchronous input. Output on hold Same color Different color Same color Same color This status can be on hold so that unwanted color objects can be ignored while they are passing the sensing range. A-156 Standard Photoelectric Sensors Remote teaching (remote control function) Mode Setting When using remote teaching (remote control function), you must set the Sensor to mode B.
