C E

Features

Double Indication ensuring high visibility.

• 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. (Threshold level indicators)

Stable and Powerful Detection for Inline Use

Stable detection is assured with a threshold of ± 10mm for built-in amplifier type and ± 4mm for optical fiber type.

Fiber type and Stable detection ± 4 mm.

Stable and Powerful Detection for Inline Use

Mounting is easy.

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) 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^ to 55^ 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 re-adjusted every nine months or so.)

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-tech, 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.

Note: The monitor photodiode compensates LED output deviation that may be caused by a temperature change. (Patent pending)

Application

Features

Excellent Protective Structure and Maintenance Performance

The amplifier unit uses a sturdy metal body. The unit including the fiber head satisfies the water resistance of IEC Standard IP66. You can use the E3MC without any problems in a wide range of applications. In addition to this, the M12 metal connector has improved maintenance performance.

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 a superior 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)

Conversion of Color Data into RGB Analog Data

The analog output type can control the color change history and distribution in analog form. Different type discrimination can also be performed without bank restrictions by CPU processing.

• Function Switches (Setting of various functions)

The following settings can be made with the function switches. (Settings can be made in the RUN mode or ADJ mode.) (For the 4 output type, all channels are the target of settings.)

① 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.

I (Mode I): Color discrimination is performed according to the light intensity. This mode ensures a finer color (similar colors or neutral color such as white, gray or black) discrimination than mode C.

1. Response Time Selection (Note: Figures in parentheses are for the 4 output models.)

3 ms (6 ms): E3MC provides a stable detection of minute differences of color. Set the response

time to

3 ms for usual applications.

1 ms (2 ms): E3MC will be in quick-response operation. Set the response time to 1 ms if high-speed response is required.

1. OFF-delay Timer Setting

No indication: No timer setting

TMR: A 40 ms OFF delay timer is set for control output.

1. 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.

Note: Each pin of the function switch is factory-set to the upper position.

Setting Procedure

1-output Models (E3MC-A□/E3MC-X□/E3MC-Y□)

1. Bank Selection

Set the Mode Selector to the TEACH mode and then select the BANK using the SELECT button.

2. Color Registration

Locate the registered object at the detection point and press the TEACH button.

3. Threshold Adjustment (If Required)

Place the sensing object, press the SELECT button in the ADJ mode, and make adjustment. (Adjustment can be made without a sensing object.) The bank selected in the ADJ mode is the bank selected in the TEACH or RUN mode.

Operation

Make measurement in the RUN mode. The registered color can be selected with bank selection input.

Detection Level and Tolerance

As the detected color becomes closer to the registered color (colors look alike), the number of lit detection level indicators (green) increase. 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).

4 output Models (E3MC-MA□/E3MC-MX□/E3MC-MY□)

1. Channel Selection

Set the Mode Selector to the TEACH mode and then select the channel using the SELECT button.

2. Color Registration

Locate the registered object at the detection point and press the TEACH button.

3. Threshold Adjustment (If Required)

ADJ

(Adjustment can be made without a sensing object)
The bank selected in the ADJ mode or TEACH mode will become the bank for the RUN mode.

Detection Level and Tolerance

As the detected color becomes closer to the registered color (similar colors), the number of lit detection level indicators (green) increase. 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).

peration

Detection is made in the RUN mode. The output ON/OFF status of each channel is displayed on the channel indicators. Double-displayed channels can be checked and selected by pressing the button.

For indicating detection level and threshold value for other channels

Press the SELECT button.

For checking which channel is indicated

Press the TEACH button

BLIP

Displays the channel the detection level of which is currently indicated in (CH-OUT). (For three seconds)

Displays the selected channel in (CHOUT) (for three seconds) and indicates the detection level and threshold value of the selected channel.

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.

External synchronous input function

The measurement results will be directly output to the control output if the input from the external synchronous input terminal (pink) is set to OFF. The output will hold the previous status if the input of the external synchronous input terminal is set to ON. External synchronous input is valid in RUN or ADJ mode. As for the 4-output models, this function applies to the output of all the channels.

Remote teaching (remote control function)

Mode Setting

When using remote teaching (remote control function), you must set the Sensor to mode B.

Setting Method

Apply power to the Sensor while pressing the SELECT DOWN button and TEACH button at the same time.

Checking Method

Whether the E3MC is operating in mode A or B can be checked with the operation indicator after mode setting (indicated for 3 s) or in the TEACH mode.

Note: 1 . The Sensor is set to mode A before shipment.

1. The current mode selected does not change after the Sensor is turned OFF.
2. The remote control function is available in the RUN mode or ADJ mode only.
3. When mode B is selected, the E3MC-M□ has three outputs. In addition to this, the external synchronous input function is unusable.
4. The same switching procedure can be used for changing to mode A.

Remote Teaching Method

1 Remote teaching with manual input through a mechanical switch

Short-circuit the remote control input for 1.5 s or more to either of the following terminals according to the E3MC model.

NPN type (E3MC-□□11)	Connected to GND (blue)

Setting Procedure for Setting the E3MC-MA81

Start detection after making setting in order of the above.

Calibration

This sensor has a calibration function that sets the output voltages of RGB to the same value using the standard white. For the A and X types, use the No. 4 terminal (yellow) to set the output values to 10 V. For the Y type, use the No. 1 terminal (white) to set them to 7 V.

① Set the standard white to the detection position.
(2) Input a 24V 1 ms or more signal to the calibration terminal.
③ It takes about 600 ms to make calibration.
④ Check the RGB outputs.
(5) Remove the standard white and start detection.

Precautions

• If the color used for calibration operation is other than white-based colors, the operation is canceled to return to the previous status since the outputs cannot be set to the same value.
• Note that if the No. 1 terminal (white) is used to perform the calibration operation of the A or X type, the output values are set to 7V and its capability cannot be exhibited fully.
• If the No. 4 terminal (yellow) is used to perform the calibration operation of the Y type, the operation will be insufficient since output compensation cannot be made. Therefore, always use the No. 1 terminal (white).

Correct Use

Common to E3MC series

Design

Power Reset Time

E3MC is ready to sense an object in 100 ms after power-on. Therefore, use the devices connected to E3MC 100 ms after power-on. If the load and E3MC are connected to different power supplies, always power on E3MC first. Especially for fine detection after power-on, warm up the system for about 15 minutes.

Power OFF

The E3MC may output a single pulse when the control power supply is turned OFF. If E3MC is connected to a timer or counter to which power is supplied from an independent power supply, 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.

Technical Guide

Detection of Metal or Glossy Objects

The color detection capability will be improved by changing the mounting angle of the Sensor so that regularly reflected light will not enter. The mounting angle of the E3MC-(M)X□□ can be adjusted about 10^ with its mounting holes.

On the other hand, sensing objects such as metal or transparent plastic cases may be detected by allowing regular reflection.

Detection of White, Gray or Black Objects

When registering white, gray, black or other neutral-color objects, change the color discrimination mode to the Mode 1 mode to achieve a more stable intensity discrimination.

External Light

The E3MC may malfunction if it directly receives external light interference. Provide a cover to shut-out such external light interference.

Adjustment of Sensing Distance of General-purpose Optical Fiber Type

Unlike the E3MC-A or E3MC-X, the E3MC-Y may require adjustment of its sensing distance depending on the reflection rate. This also applies to the through-beam type.

Definition of Sensing Distance of a Reflective Fiber

• The sensing distance of reflective fiber is the sensing distance of the Sensor located obliquely to the sensing object as shown in the following illustration.
• Set to C mode and standard mode (response time), and threshold set to the standard level with an inclination angle of 20 degrees E32-CC200.etc.

Recommended Fiber: Reflective Optical Fiber

The following optical fibers are recommended for use with the E3MC-(M)Y□□.

Model	Sensing distance*1
E32-DC200	5 mm
E32-CC200*2	5 mm
E32-D32L*3	4.5 mm
E32-D11L	5 mm

1. Distance where 11 colors of standard sensing objects can be discriminated. As a typical example, 9 colors can be discriminated when 12 mm is set.
2. The fiber to be inserted into the emitter is indicated with white lines. Insert the amplifier fiber into the lower emitter section.
*3. The fiber to be inserted into the emitter is indicated with dotted yellow lines. Insert the amplifier fiber into the lower emitter section.

Recommended Fiber: Through-beam Fiber

The following optical fibers are recommended for use with the E3MC-(M)Y□□.

Model	Sensing distance
E32-TC200	30 mm
E32-T11L	60 mm
E32-T16	200 mm
E32-T17L	1.1 m

• Distance where red, yellow and blue films can be discriminated stable.

Mounting

Insertion

The inserted Fiber Unit comes in contact with the internal rubber packing first. Insert the Fiber Unit further unit it comes in contact with the innermost end.

Tightening Force

• The tightening force applied to the Fiber Unit should be as follows:

(Screwed type)

(Column ar type)

Fiber Units	Clamping torque
M3/M4 screw	0.78 Nm max.
M6 screw	0.98 Nm max.
2-dia. column	0.29 Nm max.
3-dia. column	0.29 Nm max.
E32-T16	0.49 Nm max.

• Use a proper-sized wrench.

Cutting Fiber

• Insert a fiber into the Fiber Cutter and determine the length of the fiber to be cut.
• Press down the Fiber Cutter in a single stroke to cut the fiber.

• The cutting holes cannot be used twice. If the same hole is used twice, the cutting face of the fiber will be rough and the sensing distance will be reduced. Always use an unused hole.

Connection

• Do not pull the Fiber Unit with force exceeding 9.8N or press the Fiber Unit with force exceeding 29.4N . The fiber is so thin that the utmost attention will be required to handle the fiber.
• Do not bend the end of the Fiber Unit.

• Do not apply excess force on the Fiber Units.

• The Fiber Head could break by excessive vibration. To prevent this, the following is effective:
