[. . . ] Color Sensing Digital Fiber Sensor E3X-DAC-S Easy and Reliable The Fiber Sensor That Sees in Color Color Sensing Color-sensing Engine Color Sensing Easy and Reliable . . . Featuring a Color-sensing Engine The color-sensing engine uses three parameters, RGB, to process incident light. It detects color information from the workpiece for precise detection of color differences. Intensity Detection (Conventional Type) Color Detection (Color Sensing Type) Precise Detection Color VS.

No Need to Select Changes in the three parameters are processed as a ratio, so they are not affected by light-intensity variations due to workpiece movement.

[. . . ] Installation Precautions Glossy Sensing Objects If the sensing object is glossy, detection may not be stable. If the Sensor is inclined by 5° to 20° when using a glossy sensing object, as shown below, detection capabilities can be increased and stable detection achieved. E32-CC200 or other Fiber Unit Protective cover Unlocked Locked Note:1. To maintain the fiber properties, confirm that the lock is released before removing the fibers. Be sure to lock or unlock the lock button within an ambient temperature range between -10°C and 40°C. Adjusting Mutual Interference Protection Function Light from other sensors can cause the value on the digital display to become somewhat unstable. If this occurs, reduce the threshold to create a greater margin and enable more stable detection. Shorting the Output If the output short-circuit function operates because the load connected to the control output is short-circuited, OVER/CUR will flash on the display. EEPROM Writing Error If the data is not written to the EEPROM correctly due to a power failure or static-electric noise, initialize the settings with the keys on the Amplifier Unit. Optical Communications Several Amplifier Units can be slid together and used in groups. Do not, however, slide the Amplifier Units or attempt to remove any of the Amplifier Units during operation. Others Protective Cover Always keep the protective cover in place when using the Amplifier Unit.
