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

Do not use this product under ambient conditions that exceed the
ratings.

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.
