OMRON E2K-F Technical data

Flat Proximity Sensor

E2K-F

Saves Installation Space with a Thickness of Only 10 mm

■ Flat, Built-in Amplifier Models offer excellent space efficiency and provide a 10-mm sensing distance.

■ Detects both metallic and nonmetallic objects (water, oil, glass, plastic, etc.).

■ Direct mounting onto a metallic surface is possible.

Be sure to read Safety Precautions on page 3.

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

Sensing Object Material

The E2K-F can detect almost any type of object. The sensing distance of the E2K-F, 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-F 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 E2K-F in a trial operation with the objects before using the E2K-F in actual applications.

Influence of Surrounding Metal

Separate the E2K-F from surrounding metal as shown below.

Mutual Interference

When mounting more than one E2K-F face-to-face or side-by-side, separate them as shown below.

Effects of a High-frequency Electromagnetic Field

The E2K-F 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.

● Wiring

The characteristics of the E2K-F will not change if the cable is extended. Extending the cable, however, will result in a voltage drop, so do not extend the length past 200 m.

Sensitivity Adjustment

After the Sensor is mounted, adjust the detecting sensitivity using the (12-turn) sensitivity adjuster in the way shown below.

Note: While adjusting the sensitivity, do not put your hand on the Sensor and make sure that the cable is properly secured. Failure to observe these points may affect

the detection level.

Sensitivity adjuster Adjustment procedure

Turn the sensitivity adjuster counter-clockwise using a screwdriver until the indicator lights.

Turn the sensitivity adjuster clockwise using a screwdriver until the indicator turns OFF. Then, turn the sensitivity adjuster counter-clockwise until the indicator lights again.
