Frequently Asked Questions - E2KQ-X OMRON

What is the detection distance of the sensor?

The standard detection distance is 10 mm, adjustable between 6 and 10 mm via the sensitivity adjuster.

What type of output does the sensor have?

The sensor is available with 3-wire NPN output, normally open (NO) or normally closed (NC) depending on the model.

What supply voltage is required?

The nominal supply voltage is 12 to 24 VDC, with an operating range of 10 to 30 VDC.

What materials can it detect?

It detects conductors and dielectrics. The detection distance varies depending on the material: grounded metals offer the longest range.

Is the sensor resistant to water and chemicals?

Yes, it has a housing made of fluorine resin (Teflon) resistant to oils and chemicals, and an IP66 protection rating.

How to adjust the detection distance?

Use the provided screwdriver to adjust the sensitivity adjuster located on the sensor. The distance can be set from 6 to 10 mm.

What is the response frequency?

The response frequency is 35 Hz, allowing fast object detection.

How to install the sensor to avoid interference?

Respect the minimum distances from surrounding metals and other sensors: 30 mm lateral clearance, 200 mm face-to-face, and 32 mm side-by-side.

What to do if the sensor does not work correctly?

Check the power supply, connections, detection distance and ensure the object is a conductor or dielectric. Refer to the manual for troubleshooting.

What accessories are supplied with the sensor?

The sensor is delivered with an instruction sheet, an adjusting screwdriver, and two fluorine resin lock nuts.

Correct Use

Design

Effects of Surrounding Metals

If E2K-X is embedded in metal, maintain at least the following distances between E2K-X and the metal.

* Ensure to ground the metal object, otherwise E2KQ-X will not be in stable operation.

Mutual Interference

If more than one Sensor is located face to face or in parallel, provide sufficient space between adjacent Sensors to suppress mutual interference as indicated in the following diagram.

Effect of High-frequency Electro-magnetic Field

E2KQ-X may malfunction if there is an ultrasonic washer, high-frequency generator, transceiver, or inverter nearby. For a typical measure refer to the "Noise" with Common precautions of a photoelectric sensor in Rear B-page.

Installation

The tightening torque must not exceed the following value.

Model	Tensile strength (torque)
E2KQ-X10ME1	0.6 Nm

- Adjustment

Sensing object

The maximum sensing distance will decrease if the sensing object is a metal or dielectric object that is not grounded.

- Sensing Object Material E2K-C can detect almost any type of object. The sensing distance of 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 E2K-C will be available if the object is made of grounded metal.

- Ensure a constant ambient operating temperature during the indirect detection of objects.

Miscellaneous

Ambient Conditions

Ensure that the E2K-X is free from sprayed water, oil, chemical, or condensation, otherwise E2K-X may malfunction by detecting them as sensing objects.

Environment

E2KQ-X has a water-resistant design. To increase the reliability of E2KQ-X in operation, however, it is recommended that E2KQ-X is free from sprayed water or machining oil.

The cord is not coated with Teflon, which must be taken into consideration when installing the E2KQ-X.
