Precautions
Design
Sensing Object Material
E2K-F can detect almost any type of object. The sensing dis-
tance of E2K-F, however, will vary with the electrical charac-
teristics of the object, such as the conductance and
inductance of the object, as well as the water content and ca-
pacity 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. There-
fore test E2K-F in a trial operation with the objects before us-
ing E2K-F in actual applications.
Effects of Surrounding Metal
Separate E2K-F from ambient metals as shown below.
Mutual Interference
If installing more than one E2K-F face to face or side by side,
separate them as shown below.
Effect of High-frequency Electro-magnetic Field
E2K-F may malfunction if an ultrasonic washer, high-frequen-
cy generator, transceiver, or inverter are nearby.
For a typical measure, refer to the "Noise" with Common pre-
cautions of a photoelectric sensor in Rear B-page.
Wiring Considerations
The characteristics of E2K-F will not change if the cord is ex-
tended. 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.
