Flat Proximity Sensor
E2K-F
Saves Installation Space with a
Thickness of Only 10 mm
• Flat, Built-in Amplifier Models offer excellent space efficiency and
provide a 10-mm sensing distance.
• Detects both metallic and nonmetallic objects (water, oil, glass,
plastic, etc.).
• Direct mounting onto a metallic surface is possible.
Be sure to read Safety Precautions on
page 3.

Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use this product under ambient conditions that exceed the
ratings.
● Design
Sensing Object Material
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
Separate the E2K-F from surrounding metal as shown below.
Mutual Interference
When mounting more than one E2K-F face-to-face or side-by-side,
separate them as shown below.
Effects of a High-frequency Electromagnetic Field
The E2K-F may malfunction if there is an ultrasonic washer, high-
frequency 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.
