Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Do not use this product under ambient conditions that exceed the
ratings.
● Design
Ambient Environment
The Sensor may malfunction if subjected to water, oil, chemicals, or
condensation by falsely detecting these as sensing objects.
The E2K-X15M is highly sensitive to inductive objects and can thus
be affected even by small quantities of water drops.
Influence of Surrounding Objects
If the Sensor is embedded in metal, maintain at least the following
distances between the Sensor and the metal. The Sensor is also
affected by other materials, such as resins. Separate the Sensor from
other materials by the same distance as for metal.

E2K-X
Sensing Objects
The maximum sensing distance will decrease if the sensing object is
a non-grounded metal object or dielectric object.
• Sensing Object Material
The E2K-X can detect almost any type of object. The sensing
distance of the E2K-X, 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-X 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-X in a trial operation with the objects before
using the E2K-X in actual applications.
Effects of a High-frequency Electromagnetic Field
The E2K-X may malfunction if there is an ultrasonic washer, high-
frequency generator, transceiver, or inverter nearby.
For major measures, refer to Noise of Warranty and Limitations of
Liability for Photoelectric Sensors.
Mounting
Do not tighten the nut with excessive force. Always use washers when
tightening the nuts and do not exceed the torque in the following table.
