E3C-LDA8AT

**Photoelectric Sensor with Separate Digital Amplifier (Laser-type) E3C-LDA** 

CSM_E3C-LDA_DS_E_4_2 

## **Variable Laser Beam for Spot, Line, or Area Detection** 

- Long-distance detection (diffuse reflective: 1 m, retro-reflective: 7 m). 

- Beam shape selectable from spot, line, and area types to match various applications. 

- Adjustable spot diameter. 

- Adjustable optical axis. 

- The E3DC-LDA0, which supports the EtherCAT Sensor Communications Unit and the CompoNet Sensor Communications Unit, is also included in product lineup. 

**Refer to** _**Safety Precautions**_ **on page 9.** 

For the most recent information on models that have been certified for safety standards, refer to your OMRON website. 

## **Features** 

■ All three beam types provide ample long-distance detection of 1,000 mm. 

Three beam types means a wider variety of applications.

- *1. Sensing distance values are for white paper. 

- *2. These sensing distance values apply when a E39-R12 Reflector is used. The MSR function is built-in. The reflected light from the object being measured may affect the sensing accuracy, so adjust the threshold value before use. 

- *3. The beam radius is the value for the middle measurement distance and indicates a typical value for the middle sensing distance. The radius is defined by light intensity of 1/e[2] (13.5%) of the central light intensity. 

Light will extend beyond the main beam and may be affected by conditions surrounding the object being measured. 

- *4. The E3C-LR12 has a fixed beam size (the focal point cannot be changed).

**E3C-LDA** 

## **Precautions for Correct Use** 

Do not use the product in atmospheres or environments that exceed product ratings. 

Official laser safety measures have been established regarding laser devices both inside and outside of Japan. For details, refer to _Laser Beam Safety Standards_ . 

## **Amplifier Units** 

## ● **Designing** 

## **Operation after Turning Power ON** 

The Amplifier Unit is ready to operate within 200 ms after the power supply is turned ON. If the Sensor and load are connected to power supplies separately, be sure to turn ON the power supply to the Sensor first. 

## **Cleaning** 

Do not use thinner, benzene, acetone, or kerosene. If the filter on the front of the sensor becomes soiled with dust, oil droplets, or other materials, 

## ● **Mounting** 

## **Mounting and removing the sensor head** 

1. Open the protective cover. 

2. With the locking lever on the sensor head connector facing up, insert the connector into the connector opening. 

**==> picture [28 x 42] intentionally omitted <==**

**----- Start of picture text -----**<br>
1<br>2<br>**----- End of picture text -----**<br>


To remove the connector, press down on the locking lever and pull the connector out. 

**==> picture [27 x 5] intentionally omitted <==**

**----- Start of picture text -----**<br>
Lock lever<br>**----- End of picture text -----**<br>


- (a) Use a blower brush (used to clean camera lenses) to blow large dust particles from the surface. Do not blow the dust away with your mouth. 

- (b) Use a soft cloth (for cleaning lenses) with a little alcohol to remove the remaining dust. 

- **Note:** Do not use a scrubbing action when cleaning as a scratch on the filter could result in the Sensor malfunctioning. 

## **About the object** 

Measurement may not be possible or may not be precise with some types of object materials and shapes (such as transparent objects, objects with extremely low reflectance, objects smaller than the beam diameter, objects with a large curvature, highly tilted objects, etc). 

## **Connecting and Disconnecting Connectors (Mounting Connectors)** 

1. Insert the Master or Slave Connector into the Amplifier Unit until it clicks into place. 

**==> picture [15 x 5] intentionally omitted <==**

Insert<br>**----- End of picture text -----**<br>


2. Attach the protector seals (provided as accessories) to the sides of master and slave connectors that are not connected.

**Note:** Attach the seals to the sides with grooves. 

## **(Removing Connectors)** 

1. Slide the slave Amplifier Unit(s) for which the Connector is to be removed away from the rest of the group. 

2. After the Amplifier Unit(s) has been separated, press down on the lever on the Connector and remove it. (Do not attempt to remove Connectors without separating them from other Amplifier Units first.)

## **Beam shape adjustment function** 

The shape of the beam at each sensing distance can be adjusted by turning the beam shape control. 

## **(E3C-LD11/-LR11)** 

Turn the control to the left to adjust the focal position to short distance detection. Turn the control to the right to adjust the focal position to long distance detection. 

## **(E3C-LD21)** 

Turn the control to the left to decrease the beam width. Turn the control to the right to increase the beam width. 

## **(E3C-LD31)** 

Turn the control to the left to decrease the beam area. Turn the control to the right to increase the beam area. 

Do not turn the beam shape control to more than 60 mN⋅m. Otherwise, this may damage the unit. 

**==> picture [78 x 20] intentionally omitted <==**

**----- Start of picture text -----**<br>
Do not turn the beam shape<br>control to more than 60 mN·m.<br>This may damage the unit.<br>**----- End of picture text -----**<br>


## **(Separating Amplifier Units)** 

Slide Amplifier Units away from each other, and remove from the DIN track one at a time. (Do not attempt to remove Amplifier Units from the DIN track without separating them first.) 

- **Note: 1.** The specifications for ambient temperature will vary according to the number of Amplifier Units used together. For details, refer to _**Ratings and Specifications**_ on page 5. 

   **2.** Always turn OFF the power supply before mounting or separating Amplifier Units. 

## **Mounting the End Plate (PFP-M)** 

An End Plate should be used if there is a possibility of the Amplifier Unit moving, e.g., due to vibration. If a Mobile Console is going to be mounted, connect the End Plate in the direction shown in the following diagram. 

**==> picture [88 x 45] intentionally omitted <==**

**==> picture [26 x 5] intentionally omitted <==**

**----- Start of picture text -----**<br>
End Plate<br>**----- End of picture text -----**<br>


## **Mounting the Mobile Console Head** 

Leave a gap of at least 20 mm between the nearest Amplifier Unit and the Mobile Console head. 

**==> picture [14 x 28] intentionally omitted <==**

**----- Start of picture text -----**<br>
20 mm<br>**----- End of picture text -----**<br>


## **Optical axis alignment function** 

The angle of beam projection can be adjusted by turning the optical axis alignment control. 

Turning the control about 45° to the right will move the optical axis to the left by the number of degrees shown below. 

Turning the control about 45° to the left will move the optical axis to the right by the number of degrees shown below. 

If the act of adjusting the optical axis changes the beam shape, adjust the beam shape again. Turning the control 180° will return the optical axis to its original position. 

Adjustment angle E3C-LR11 : Approx. 1.5° E3C-LR12 : Approx. 1.0° E3C-LD **@@** : Approx. 2.0° 

## **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. ERR/EEP will flash on the display when a writing error has occurred. 

## **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. 

## ● **Other Precautions** 

## **Protective Cover** 

Always keep the protective cover in place when using the Amplifier Unit. 

## **Mobile Console** 

## ● **Adjustments** 

Use the E3X-MC11-C1-SV2 Mobile Console for the E3C-LDA-series Amplifier Units. 

## **Mutual Interference Protection Function** 

There may be some instability in the digital display values due to light from other sensors. If this occurs, decrease the sensitivity (i.e., decrease the power or increase the threshold) to perform stable detection.

However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to confirm actual specifications of purchased Product.
