● Adjustment
Sensing Object
The maximum sensing distance will decrease if the sensing object is
a non-grounded metal object or dielectric object.
• Sensing Object Material
The E2KQ-X can detect almost any type of object. The sensing
distance of the E2KQ-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 E2KQ-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 E2KQ-X in a trial operation with the objects before
using the E2KQ-X in actual applications.

● Miscellaneous
Ambient Environment
Environment
The Sensor may malfunction if subjected to water, oil, chemicals, or
condensation by falsely detecting these as sensing objects.
The E2KQ-X is of water-resistant construction. To increase the
reliability of the E2KQ-X in operation, however, it is recommended
that the E2KQ-X be protected with an appropriate cover so that the
E2KQ-X will be free from sprayed water or machining oil.
The cable is not coated with Fluororesin, which must be taken into
consideration when installing the E2KQ-X.
