RGB Color Sensor E3MC RGB Color Sensor Discriminates Delicate Differences in Color. Best Color Sensor in the Industry. Built-in LED light source ensures long service life and maintenance-free operation. Discriminates differences in color without being influenced by changes in ambient temperature, brightness of sensing objects, or positioning of sensing objects. Models with built-in amplifiers for long-distance sensing and those with fiber heads for tiny spot sensing are available. Incorporates easy-to-see detection level and threshold level indicators. Degree of protection to IP66 and easy to maintain. 4-color registration/4-output models are also available.

(6 ms) 3 ms Note: Figures in parentheses are for the 4-output models. 1 ms (2 ms) Color Discrimination Mode Selection (Mode C is Recommended for Normal Applications) Mode C: Color discrimination is performed according to R (red), G (green), and B (blue) ratio of the reflection light even if the sensing objects fluctuate up and down within the rated sensing range. Mode I: Color discrimination is performed according to RGB light intensity of reflection light. This mode ensures more delicate color discrimination than mode C. Response Time Selection (Note: Figures in parentheses are for the 4-output models.) 3 ms (6 ms): The E3MC can stably detect minute differences of color. Set the response time to 3 ms for usual applications. 1 ms (2 ms): The E3MC will be in quick-response operation. Set the response time to 1 ms if high-speed response is required. OFF-delay Timer Setting ---: No OFF-delay timer is set. TMR: A 40-ms OFF-delay timer is set for control output. Conformity/Non-conformity Output =: Output is ON when the detected color coincides with the registered color. ≠: Output is ON when the detected color does not coincide with the registered color.

To prevent Insert the fiber into one of the insertion holes of the Cutting Tool to this, the following is effective: cut the fiber to the desired length. Press down the blade of the Cutting Tool to cut the fiber in a single stroke. Do not stop the Cutting Tool midway. A one-turn loop can absorb vibrations.

Be sure to turn ON the E3MC first if power is supplied to the Do not bend the Fiber Unit beyond the permissible bending radius E3MC and the load independently. provided in Ratings/Characteristics. When the E3MC is turned ON or OFF, the operation indicator will be Do not bend the end of the Fiber Unit. ON for an instant but no control output will be turned ON. When using the Sensor for fine sensing, allow the system to warm 20 mm min. up for approximately 15 min after turning ON the power supply. Power OFF The E3MC may output a single pulse when the control power supply is turned OFF. If the E3MC is connected to a timer or counter to Fiber Unit Amplifier which power is supplied from an independent power supply, the E3MC will be more likely to output a single pulse when the control power supply is turned OFF. Therefore, supply power to the timer or counter from the same power supply for the E3MC. 20 mm min. Types of Power Supplies No full-wave or half-wave rectified power supplies can be con- nected to the E3MC. Amplifier Fiber Unit Power Supplies Be sure to ground the FG (frame ground) and G (ground) terminals if a switching regulator is connected to the E3MC, otherwise the E3MC may malfunction due to the switching noise of the switching Do not press or place a load on the Fiber Unit. regulator. Wiring Correct Fiber Unit Cord Nylon wire holder The cord can be extended up to 100 m provided that the thickness of 2 the cord is 0.3 mm maximum. Repeated Bending Incorrect The cord must not be bent repeatedly. High-tension Lines The power supply lines of the Photoelectric Sensor must not be wired alongside power lines or high-tension lines in the same con- duit, otherwise the Photoelectric Sensor may become damaged or The Fiber Head can be broken by excessive vibration. To prevent malfunction due to induction noise that may be generated from the this, the following is effective. power lines or high-tension lines. Route the lines separately or in a single conduit. Cord Pulling Force A one-turn loop can absorb vibrations. Do not pull cords with pulling forces exceeding 50 N.

Tighten the metal connector securely by hand. Do not use any tool, such as pliers, otherwise the metal connector may be damaged. If the metal connector is not tightened securely, the metal connector may be disconnected by vibration or the proper degree of protection of the E3MC may not be maintained. Water Precaution Avoid using the Sensor in water, rain, or outdoors. Protective Cover Tighten the operation cover to a torque of 0.2 to 0.3 N � m to ensure proper waterproofing. 19 E3MC E3MC 4.
