Refer to Engineering Data for sensing distances applicable to other types of objects. Current flows in this direction if the circuit incorporates the transistor. Remove this rubber cap and adjust the potentiometer. Turn the potentiometer counterclockwise until the E2K-C turns off with the sensing object located within the sensing distance. Potentiometer Stop turning the potentiometer at the moment the E2K-C turns off.

Detects both metallic and nonmetallic objects water, plastic, etc. Noise-resistant Models added to the lineup for application in a wide range of industrial environments. Be sure to read Safety Precautions on page 7. Ordering Information Sensors [Refer to Dimensions on page 8. Refer to Engineering Data on page 4 for other materials.
Refer to Engineering Data on page 4. The set distances are sensing distances applicable to standard sensing objects. The response frequency is an average value.
Only 2-m cables are available. Use a cable with a conductor cross section of 0. Load current: mA max. When a transistor is connected. Do not use it for such purposes. 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.
Precautions for Correct Use Do not use this product under ambient conditions that exceed the ratings. Sensing Objects? 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. When mounting the Sensor with the L-shaped Mounting Bracket, be sure to provide a distance of 20 mm min.
Sensing is enabled within ms for the E2K-C20M. Design the system so that the power for the Sensor is turned ON before the power for the load. Sensing surface Be sure to ground. Metal 80 mm min. Be sure that the case is free from organic solvents or solutions containing organic solvents. Mutual Interference When installing Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained.
C Models: 5. Drill through the holes before using them. In no event shall the responsibility of OMRON for any act exceed the individual price of the product on which liability is asserted.
