**Note:** Incorrect detection may occur outside the measurement range if the object has a high reflection factor.
- *1. These Sensors are classified as Class 1 laser devices under IEC 60825-1 and the regulations of Laser Notice No. 50 for FDA certification. CDRH (Center for Devices and Radiological Health) registration has been completed. (Accession Number: 1220691)
- *2. The values were measured at the center of the sensing distance using OMRON’s standard sensing object (white ceramic).
- *3. Beam size: Defined at the 1/e[2] (13.5 %) of the central intensity at the measurement center distance.
Measurement may be influenced if there is light leakage outside the defined region and the surroundings of the target object have a high reflectance in comparison to the target object.
Also, when detecting a workpiece that is smaller than the beam size, a correct value may not be obtained.

## **Precautions for Safe Use**
The following precautions must be observed to ensure safe operation of the Sensor Head.
**1.** Installation Environment
- Do not use the Sensor Head in an environment where explosive or flammable gas is present.
- To secure the safety of operation and maintenance, do not install the Sensor Head close to high-voltage devices or power devices.
**2.** Power Supply and Wiring
- Always use an E3NC-LA @@ , E3NC-LA0, E3NC-SA @@ or E3NCSA0 Amplifier Unit. If a different Amplifier Unit is used, damage or fire may occur.
- If you short the cable, reconnect it as specified. If the connections are not correct, damage or fire may occur.
- High-voltage lines and power lines must be wired separately from the Sensor Head. Wiring them together or placing them in the same duct may cause induction, resulting in malfunction or damage.
- Always turn OFF the power supply before connecting or disconnecting the connectors.
**3.** Installation
- Use screws for installation and tighten the screws securely, but do not exceed the specified tightening torque. Specified torque (M3): 0.5 N·m
**4.** Others
- Never disassemble (including removing labels), repair, modify, deform by pressure, or incinerate the Sensor Head. Do not turn the adjuster on the E3NC-LH02 with a force that is greater than 40 mN·m. Damage or fire may occur.
- Dispose of the Sensor Head as industrial waste.
- If you notice any abnormalities, immediately stop using the Sensor Head, turn OFF the power supply, and contact your OMRON representative.
**5.** Conditions of UL
- (Applicable Models: E3NC-LH01/LH02 Only)
- The E3NC-LH series sensor head accessories shall be used with the E3NC-LA amplifiers.
- These amplifiers and sensor head accessories shall be installed within a suitable enclosure where all components, including cords and connectors, shall be entirely contained within the same enclosure.
**2.** Warming Up
- The circuits will be unstable just after the power supply is turned ON, so measurement values may fluctuate gradually.
- For accurate measurements, allow the product to stand for at least 10 minutes after turning ON the power supply before use. (E3NCS Series)
**3.** Maintenance and Inspection
- Always turn OFF the power supply before adjusting or connecting/ disconnecting the Sensor Head.
- Do not use thinner, benzene, acetone, or kerosene to clean the Sensor Head.
- If large dust particles or dirt adheres to the filter on the front of the Sensor Head, use a blower brush (such as one used to clean camera lenses) to blow it off. Do not blow the dust particles or dirt with your mouth. To remove dust particles or dirt, wipe it off gently with a soft cloth (such as one for cleaning lenses) moistened with a small amount of alcohol. Do not wipe it off with excessive force. Scratches on the filter may cause errors.
**4.** Sensing Object
- The Sensor Head cannot accurately measure objects with the following materials and shapes: Transparent objects (with the E3NC-LH03, objects that are extremely transparent), objects with an extremely low reflection ratio, objects smaller than the spot diameter, objects with a large curvature, excessively inclined objects, etc. Also, for long-distance detection, the Sensor may falsely operate if a white object approaches near the Sensor Head (E3NC-LH03).
**5.** Do not use the Sensor in water, rainfall, or outdoors.
**6.** A ferrite core is attached to the Sensor Head end of the cable connected to the E3NC-LH03 5M. Do not remove the ferrite core or change its position. Also, do not bend the cable within 12 mm of each end of the ferrite core. Doing so may damage the cable.
## **Attaching a Reflector**
Mount the Reflector as shown in (Correct) below. Errors will be generated if you mount it at the angle shown in (Incorrect). Always install the Reflector at the same angle as the Sensor Head if the head is not mounted vertically or horizontally.
## **Common for all models**
