Safety Precautions Refer to Warranty and Limitations of Liability. 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 mounting more than one E2K-F face-to-face or side-by-side, separate them as shown below. 40 mm Precautions for Correct Use 50 mm 50 mm Do not use this product under ambient conditions that exceed the ratings. ● Design Sensing Object Material Close mounting possible Face-to-face mounting Effects of a High-frequency Electromagnetic Field The E2K-F can detect almost any type of object. The sensing distance of the E2K-F, 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-F 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-F in a trial operation with the objects before using the E2K-F in actual applications. Influence of Surrounding Metal The E2K-F 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. ● Wiring The characteristics of the E2K-F will not change if the cable is extended. Extending the cable, however, will result in a voltage drop, so do not extend the length past 200 m. Separate the E2K-F from surrounding metal as shown below. 30 mm ● Mounting Sensitivity Adjustment For information on the sensitivity adjustment, refer to Technical Guide for Operation for information for Proximity Sensor. 60 mm Metal object 45 mm Metal object Metal object 3 E2K-F (Unit: mm) Dimensions Tolerance class IT16 applies to dimensions in this data sheet unless otherwise specified.
