(load current) Precautions Correct Use Design Sensing Object Material E2K-F can detect almost any type of object. The sensing distance of E2K-F, however, will vary with the electrical characteristics of the object, such as the conductance and inductance of the object, as well as the water content and capacity of the object. The maximum sensing distance of E2K-F will be available if the object is made of grounded metal. There are objects that cannot be detected indirectly. Therefore test E2K-F in a trial operation with the objects before using E2K-F in actual applications. Effects of Surrounding Metal Separate E2K-F from ambient metals as shown below. 30mm Mutual Interference If installing more than one E2K-F face to face or side by side, separate them as shown below. 40mm 50mm 50mm Close mounting possible Face-to-face mounting Effect of High-frequency Electro-magnetic Field E2K-F may malfunction if an ultrasonic washer, high-frequency generator, transceiver, or inverter are nearby. For a typical measure, refer to the "Noise" with Common precautions of a photoelectric sensor in Rear B-page.
