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
Influence of Surrounding Metal
When mounting a Proximity Sensor, be sure to provide a distance of
80 mm min. from surrounding metal objects to prevent the Sensor
from being affected by metal objects other than the sensing object.
When mounting the Sensor with the L-shaped Mounting Bracket, be
sure to provide a distance of 20 mm min. between the face of the
sensing head and the Mounting Bracket.

E2K-C
Effects of a High-frequency Electromagnetic Field
The E2K-C 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.
Sensing Objects
x Sensing Object Material
The E2K-C can detect almost any type of object. The sensing
distance of the E2K-C, 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-C will be
obtained if the object is made of grounded metal.
x Indirect Detection
To detect objects in metal containers, each metal container must
have a nonmetallic window.
Power ON Conditions
Sensing is enabled within 200 ms for the E2K-C20M@@. Design the
system so that the power for the Sensor is turned ON before the
power for the load.
● Miscellaneous
Organic Solvents
The Sensor has a case made of heat-resistant ABS resin or PBT
resin. Be sure that the case is free from organic solvents or solutions
containing organic solvents.
