WARNING Effects of a High-frequency Electromagnetic Field This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. The E2K-C may malfunction if there is an ultrasonic washer, highfrequency generator, transceiver, portable telephone or inverter nearby. For major measures, refer to Noise of Warranty and Limitations of Liability for Photoelectric Sensors. Precautions for Correct Use Do not use this product under ambient conditions that exceed the ratings. ● Design Influence of Surrounding Metal When mounting a Proximity Sensor, be sure to provide a distance of 80 mm min. from surrounding metal objects to prevent the Sensor from being affected by metal objects other than the sensing object. When mounting the Sensor with the L-shaped Mounting Bracket, be sure to provide a distance of 20 mm min. between the face of the sensing head and the Mounting Bracket. 80 mm min. Be sure to ground. 80 mm min. 80 mm min. Metal Surrounding conductive objects Sensing surface • Sensing Object Material The E2K-C can detect almost any type of object. The sensing distance of the E2K-C, 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-C will be obtained if the object is made of grounded metal. • Indirect Detection To detect objects in metal containers, each metal container must have a nonmetallic window. Power ON Conditions Surrounding conductive objects 20 mm min. Sensing Objects 80 mm min. Mutual Interference When installing Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained. Face-to-face Mounting Sensing is enabled within 200 ms for the E2K-C20M@@. Design the system so that the power for the Sensor is turned ON before the power for the load. ● Miscellaneous Organic Solvents The Sensor has a case made of heat-resistant ABS resin or PBT resin. Be sure that the case is free from organic solvents or solutions containing organic solvents.
