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

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.

Mutual Interference

When installing Sensors face-to-face or side-by-side, ensure that the

minimum distances given in the following table are maintained.

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

• 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.

• 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.
