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

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.

Wiring Considerations The characteristics of E2K-F will not change if the cord is extended. Keep in mind that voltage drops may occur due to the cord extension, thus, ensure that the total cord length does not exceed 200 m.
