WARNING Mutual Interference This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. When installing Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained. Precautions for Correct Use B A Do not use this product under ambient conditions that exceed the ratings. Mutual Interference Model ● Design Influence of Surrounding Metal (Unit: mm) Dimension [email protected] If the E2KQ-X is embedded in metal, maintain at least the following distances between the E2KQ-X and the metal. l m n d dia. A B 200 32 Effects of a High-frequency Electromagnetic Field The Sensor may malfunction if there is an ultrasonic washer, highfrequency generator, or transceiver nearby. For major measures, refer to Noise of Warranty and Limitations of Liability for Photoelectric Sensors. ● Mounting Be sure to tighten each nut with torque not exceeding the following value. * Be sure to ground. Metal object Model * Be sure to ground the metal object, otherwise E2KQ-X operation will not be stable. Influence of Surrounding Metal Model Dimension [email protected] (Unit: mm) l d m n 30 75 18 90 If a mounting bracket is used, be sure that at least the following distances are maintained. G Influence of Surrounding Metal (Unit: mm) Model Dimension [email protected] G H 30 35 H [email protected] Torque 0.6 N·m ● Adjustment Sensing Object The maximum sensing distance will decrease if the sensing object is a non-grounded metal object or dielectric object. • Sensing Object Material The E2KQ-X can detect almost any type of object. The sensing distance of the E2KQ-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 E2KQ-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 E2KQ-X in a trial operation with the objects before using the E2KQ-X in actual applications. 3 E2KQ-X ● Miscellaneous Ambient Environment Environment The Sensor may malfunction if subjected to water, oil, chemicals, or condensation by falsely detecting these as sensing objects. The E2KQ-X is of water-resistant construction. To increase the reliability of the E2KQ-X in operation, however, it is recommended that the E2KQ-X be protected with an appropriate cover so that the E2KQ-X will be free from sprayed water or machining oil. The cable is not coated with Fluororesin, which must be taken into consideration when installing the E2KQ-X.
