Precautions
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.
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.
Sensing Object
•
Sensing Object Material. The E2K-C can detect almost
any type of object. The sensing distance of the E2K-C, how-
ever, will vary with the electrical characteristics of the ob-
ject, such as the conductance and inductance of the object,
and the water content and capacity of the object. The max-
imum sensing distance of E2K-C will be available if the ob-
ject is made of grounded metal.
•
Indirect Detection. In the case of the detection of objects
in metal containers, each metal container must have a non-
metallic window.
Miscellaneous
Organic Solvents
E2K-C has a case made of heat-resistant ABS resin. Be sure
that the case is free from organic solvents or solutions con-
taining organic solvents.
