E3T-FT24 2M

**Ultracompact, Ultrathin Photoelectric Sensor with Built-in Amplifier E3T** 

## **The Improved E3T Series with Easier, Smoother Mounting and Installation** 

- The series includes Through-beam, Long-distance (2 m) Sensors (E3T-ST3@). 

- Easy installation with M3-mounting Sensors (E3T-ST@@M, E3T-FD@@M, and E3T-SL@@M). 

- Small Cylindrical Sensors for one-point mounting are also available (E3T-C@@@(S)). 

- Infrared Sensors added to the Series 

- (E3T-@T@@(M)F).

- *1. The model number of the Emitter is expressed by adding an “L” to the set model number in the table. Example: E3T-ST11-L 2M The model number of the Receiver is expressed by adding a “D” to the set model number in the table. Example: E3T-ST11-D 2M 

- *2. Values in parentheses indicate the minimum required distance between the Sensor and Reflector. 

- *3. Models are available either with or without the E39-R37-CA Reflector included. Models with E39-R37-CA Reflector: E3T-SR4 @ -S Models without Reflector: E3T-SR4 @ -C 

- *4. Models with robot (bending-resistant) cable are also available with “R” in the model number. (Example: E3T-ST11R 2M)

**E3T** 

## **Safety Precautions** 

## **Refer to** _**Warranty and Limitations of Liability**_ **.** 

## **WARNING** 

**This product is not designed or rated for ensuring safety of persons. Do not use it for such purpose.** 

## ● **Adjusting** 

## **Indicators** 

- The following graphs indicate the status of each operating level. 

- Be sure to use the E3T within the stable operating range. 

**Do not apply AC power to the E3T, otherwise the E3T may rupture.** 

## **Precautions for Correct Use** 

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

## ● **Wiring** 

The maximum power supply voltage is 26.4 VDC. Before turning the power ON, make sure that the power supply voltage is not more than maximum voltage. 

## **Load short-circuit protection** 

The E3T incorporates a load short-circuit protection function. If the load short-circuits, the output of the E3T will be turned OFF. Then, recheck the wiring and turn on the E3T again to reset the load shortcircuit protection function. The load short-circuit protection function will work if there is a current flow that is 1.5 times larger than the rated load current. When using a capacitance load, be sure that the inrush current will not exceed 1.5 times larger than the rated current. 

## ● **Mounting** 

When mounting the Sensor, never strike it with a heavy object, such as a hammer. Doing so may reduce its watertight properties. Use screws with spring, flat, or toothed washers to secure the Sensor. Tightening Torque M2-mounting Sensors: 0.15 N·m max M3-mounting Sensors: 0.5 N·m max Small Cylindrical Sensors: 1 N·m max 

## **Attachment to Moving Parts** 

To mount the Photoelectric Sensor to a moving part, such as a robot hand, consider using a Sensor that uses a bending-resistant cable (robot cable).

- If the E3T’s operating level is set to the stable operation range, the E3T will be in most reliable operation without being influenced by temperature change, voltage fluctuation, dust, or setting change. If the operating level cannot be set to the stable operation range, pay attention to environmental changes while operating the E3T. 

## **Use of E39-E10 Sensitivity Adjustment Unit**

**----- Start of picture text -----**<br>
(At Min.) (At Center) (At Max.)<br>Indicator<br>Adjuster<br>**----- End of picture text -----**<br>


1. Mount the Unit on the Receiver. 

2. Set the adjuster of the Sensitivity Adjustment Unit to Max. (Before shipping: Max.) 

3. After mounting on the Sensor, adjust the optical axis and secure the Sensor. 

4. Place a workpiece between the Emitter and Receiver and gradually turn the adjuster counterclockwise toward the Min. side. Stop turning the adjuster when the operation indicator and stability indicator (green) turn ON. 

5. Remove the workpiece and confirm that the operation indicator is OFF and the stability indicator (green) is ON. This completes the adjustment. 

Note: If the light attenuation rate due to a workpiece is 40% or less, the stability indicator will not turn ON whether or not light is received. When the variation of light is small such as when sensing semi-transparent workpieces, carefully perform preliminary testing. 

## **E3T-CD@@ Sensitivity Adjustment** 

Use the special screwdriver that is provided with the Sensor to adjust the sensitivity. Do not exceed 0.8 N·cm when turning the adjuster. 

## ● **Others** 

## **Do not use the product under the following conditions.** 

- In the place exposed to the direct sunlight. 

- In the place where humidity is high and condensation may occur. 

- In the place where corrosive gas exists. 

- In the place where vibration or shock is directly transmitted to the product.

Return of any Products by Buyer must be approved in writing by Omron before shipment. Omron Companies shall not be liable for the suitability or unsuitability or the results from the use of Products in combination with any electrical or electronic components, circuits, system assemblies or any other materials or substances or environments. Any advice, recommendations or information given orally or in writing, are not to be construed as an amendment or addition to the above warranty. 

See http://www.omron.com/global/ or contact your Omron representative for published information. 

## **Limitation on Liability; Etc.** 

OMRON COMPANIES SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY. 

Further, in no event shall liability of Omron Companies exceed the individual price of the Product on which liability is asserted. 

## **Suitability of Use.** 

Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.

## **Performance Data.** 

Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability. 

## **Change in Specifications.** 

Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed, or when significant construction changes are made. 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.
