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
Influence of Surrounding Metal
If the E2KQ-X is embedded in metal, maintain at least the following
distances between the E2KQ-X and the metal.
* Be sure to ground the metal object, otherwise E2KQ-X operation will not be
stable.
Influence of Surrounding Metal (Unit: mm)
If a mounting bracket is used, be sure that at least the following
distances are maintained.
Mutual Interference
When installing Sensors face-to-face or side-by-side, ensure that the
minimum distances given in the following table are maintained.
Mutual Interference (Unit: mm)
Effects of a High-frequency Electromagnetic Field
The Sensor may malfunction if there is an ultrasonic washer, high-
frequency generator, or transceiver nearby.
For major measures, refer to Noise of Warranty and Limitations of
Liability for Photoelectric Sensors.
● Mounting
Be sure to tighten each nut with torque not exceeding the following value.
● 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.
