Long-distance capacitive proximity sensor
E2K-C
Capacitive Proximity Sensor
with Adjustable Sensitivity
● Detects both metallic and non-metallic objects
(glass, lumber, water, oil, plastic, etc.) without
direct contact.
● DC models acquire CE marking

Operation
Sensitivity adjustment
Remove the rear rubber cap of the E2K-C and turn the poten-
tiometer in the hole to adjust the sensitivity of the E2K-C.
Remove this rubber
cap and adjust the
potentiometer.
The sensing distance increases by turning the potentiometer
clockwise and decreases by turning the potentiometer coun-
terclockwise. The potentiometer can make 15±3 valid turns
and then make slip turns because the potentiometer does not
have a stopper. The slip turns will not, however, damage the
potentiometer.
1. Slowly turn the potentiometer clockwise until the E2K-C
turns on with no sensing object.
Potentiometer
Stop turning the potentiometer
at the moment the E2K-C turns off.
Precautions
Correct Use
Design
Effects of Surrounding Metal
During Proximity Sensor installation provide a distance of 80
mm min. from the surrounding metal objects to prevent the
Sensor from being affected by metal objects other than the
sensing object.
If installing the Sensor with the L-shaped mounting bracket,
provide a distance of 20 mm min. between the face of the
sensing head and the mounting bracket.

2. 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.
3. The E2K-C will be in stable operation if there is a difference
of 1.5 turns or more between the points the E2K-C is turned
on and off, otherwise the E2K-C will not be in stable oper-
ation.
The point the
E2K-C turns on.
Stable detection if the
difference is 1.5 turns or more.
The point the
E2K-C turns off.
4. Set the potentiometer midway between the two points.
The point the
E2K-C turns on.
Midway
The point the
E2K-C turns off.
5. If the distance of each sensing object varies, take step 2
with the sensing object located at the farthest sensing dis-
tance to be applied.
Mutual Interference
Space the two Sensors at a distance exceeding 100 mm to
prevent mutual interference.

Effect of High-frequency Electro-magnetic Field
The E2K-C may malfunction if there is an ultrasonic washer,
high-frequency generator, transceiver, or inverter nearby.
Be sure to ground
