Do not use this product under ambient conditions that exceed the ratings. 

## **Effects of a High-frequency Electromagnetic Field** 

The E2K-C may malfunction if there is an ultrasonic washer, highfrequency 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 

## ● **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.

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. 

## ● **Mounting** 

## **Sensitivity Adjustment** 

For information on the sensitivity adjustment, refer to _Technical Guide for Operation for information_ for Proximity Sensor.
