* Models numbers for Through-beam Sensors (E3Z-LT@@) are for sets that include both the Emitter and Receiver. 

- The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3Z-LT61-L 2M), the model number of the Receiver, by adding "-D" (example: E3Z-LT61-D 2M.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.

## **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.** 

## **Precautions for Correct Use** 

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

## ● **Laser Warning Labels** 

**To ensure safe use of laser products, do not allow the laser beam to enter your eye. Direct exposure may adversely affect your eyesight.** 

Be sure that the correct laser warning label (enclosed) is attached for the country of intended use of the equipment containing the Photoelectric Sensor. Refer to the user's manual for details. 

## ● **Usage Environment** 

## **Water Resistance** 

## **CAUTION** 

**Do not connect an AC power supply to the Sensor. If AC power (100 VAC or more) is supplied to the Sensor, it may explode or burn.** 

## **Precautions for Safe Use** 

The Sensor is rated IP67. Do not use it in water, in the rain, or outdoors. 

## **Ambient Environment** 

Do not install the product in the following locations. Doing so may result in product failure or malfunction. 

- Locations subject to excess dust and dirt 

- Locations subject to direct sunlight 

Be sure to abide by the following precautions for the safe operation of the Sensor. 

## ● **Operating Environment** 

Do not use the Sensor in locations with explosive or flammable gas. 

- Locations subject to corrosive gas 

- Locations subject to organic solvents 

- Locations subject to shock or vibration 

- Locations subject to exposure to water, oil, or chemicals 

- Locations subject to high humidity or condensation 

## ● **Wiring** 

## **Power Supply Voltage and Output Load Power Supply Voltage** 

Make sure that the power supply to the Sensor is within the rated voltage range. If a voltage exceeding the rated voltage range is supplied to the Sensor, it may explode or burn. 

## **Power Supply Voltage** 

The maximum power supply voltage is 26.4 VDC. Applying a voltage exceeding the rated range may damage the Sensor or cause burning. 

## **Load** 

Do not use a load that exceeds the rated load. 

## **Load Short-circuiting** 

Do not short-circuit the load, otherwise the Sensor may be damaged or it may burn. 

## **Connection without Load** 

Do not connect the power supply to the Sensor with no load connected, otherwise the internal elements may explode or burn. Always connect a load when wiring. 

## ● **Designing** 

## **Power Reset Time** 

The Sensor is ready to operate 100 ms after the Sensor is turned ON. If the load and Sensor are connected to independent power supplies respectively, be sure to turn ON the Sensor before supplying power to the load. 

## ● **Wiring** 

## **Avoiding Malfunctions** 

If using the Sensor with an inverter or servomotor, always ground the FG (frame ground) and G (ground) terminals, otherwise the Sensor may malfunction. 

## ● **Mounting** 

## **Mounting the Sensor** 

- If Sensors are mounted face-to-face, make sure that the optical axes are not in opposition to each other. Otherwise, mutual interference may result. 

- Always install the Sensor carefully so that the aperture angle range of the Sensor will not cause it to be directly exposed to intensive light, such as sunlight, fluorescent light, or incandescent light. 

- Do not strike the Photoelectric Sensor with a hammer or any other tool during the installation of the Sensor, or the Sensor will lose its water-resistive properties. 

- Use M3 screws to mount the Sensor. 

- When mounting the case, make sure that the tightening torque applied to each screw does not exceed 0.54 N·m. 

## **Metal Connectors** 

- Always turn OFF the power supply to the Sensor before connecting or disconnecting the metal connector. 

- Hold the connector cover to connect or disconnect it. 

- If the XS3F is used, always tighten the connector cover by hand. Do not use pliers. 

- If the tightening is insufficient, the degree of protection will not be maintained and the Sensor may become loose due to vibration. The appropriate tightening torque is 0.3 to 0.4 N·m. 

If other commercially available connectors are used, follow the recommended connector application conditions and recommended tightening torque specifications.

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. 

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCT(S) IS PROPERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM. 

## Programmable Products. 

Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence thereof. 

## 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. 

## Errors and Omissions. 

Information presented by Omron Companies has been checked and is believed to be accurate; however, no responsibility is assumed for clerical, typographical or proofreading errors or omissions.
