**4** **E2K-X** ## **Safety Precautions** ## **Refer to** _**Warranty and Limitations of Liability**_ **.** ## **WARNING** **This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes.** ## **Precautions for Correct Use** Do not use this product under ambient conditions that exceed the ratings. ## ● **Design** ## **Ambient Environment** The Sensor may malfunction if subjected to water, oil, chemicals, or condensation by falsely detecting these as sensing objects. The E2K-X15M is highly sensitive to inductive objects and can thus be affected even by small quantities of water drops. ## **Influence of Surrounding Objects** If the Sensor is embedded in metal, maintain at least the following distances between the Sensor and the metal. The Sensor is also affected by other materials, such as resins. Separate the Sensor from other materials by the same distance as for metal. **==> picture [186 x 88] intentionally omitted <==** **----- Start of picture text -----**

**----- End of picture text -----**
* Be sure to ground the metal object, otherwise Sensor operation will not be stable. ## **Sensing Objects** The maximum sensing distance will decrease if the sensing object is a non-grounded metal object or dielectric object. • Sensing Object Material The E2K-X can detect almost any type of object. The sensing distance of the E2K-X, however, will vary with the electrical characteristics of the object, such as the conductance and inductance of the object, and the water content and capacity of the object. The maximum sensing distance of the E2K-X will be obtained if the object is made of grounded metal. - There are objects that cannot be detected indirectly. Therefore, be sure to test the E2K-X in a trial operation with the objects before using the E2K-X in actual applications. ## **Effects of a High-frequency Electromagnetic Field** The E2K-X may malfunction if there is an ultrasonic washer, highfrequency generator, transceiver, or inverter nearby. For major measures, refer to _Noise_ of _Warranty and Limitations of Liability_ for Photoelectric Sensors. ## **Mounting** Do not tighten the nut with excessive force. Always use washers when tightening the nuts and do not exceed the torque in the following table. **==> picture [69 x 40] intentionally omitted <==** |**Model**

Be sure that the case is free from organic solvents or solutions containing organic solvents.
