E2EL
Installation
Caution
Item
Power Supply
Do not impose an excessive voltage on the E2EL, otherwise it
may explode or burn.
Do not impose 24 VAC on any E2EL model, otherwise it may
explode or burn.
Load short–circuit
Do not short–circuit the load, or the E2EL may explode or burn.
The E2EL’s short–circuit protection function is valid, if the polarity
of the supply voltage imposed is incorrect and within the rated
voltage range.
Wiring
Be sure to wire the E2EL and load correctly, otherwise it may
explode or burn.

Correct Use
Installation
Power Reset Time
The Proximity Sensor is ready to operate within 100 ms after power
is supplied. If power supplies are connected to the Proximity Sensor
and load respectively, be sure to supply power to the Proximity Sen-
sor before supplying power to the load.
Power OFF
The Proximity Sensor may output a pulse signal when it is turned off.
Therefore, it is recommended to turn off the load before turning off
the Proximity Sensor.
Power Supply Transformer
When using a DC power supply, make sure that the DC power sup-
ply has an insulated transformer. Do not use a DC power supply with
an auto–transformer.
Sensing Object
Metal Coating:
The sensing distance of the Proximity Sensor vary with the metal
coating on sensing objects.
Wiring
High–tension Lines
Wiring through Metal Conduit
If there a power or high–tension line near the cord of the Proximity
Sensor, wire the cord through an independent metal conduit to pre-
vent against Proximity Sensor damage or malfunctioning.
Core Tractive Force
Do not pull cords with the tractive force exceeding the following:
pull force (N) = 20 x cable diameter ( mm)
Mounting
The Proximity Sensor must not be subjected to excessive shock
with a ha mmer when it is installed, otherwise the Proximity Sensor
may be damaged or lose the water–resistivity.
Environment
Water–Resistivity
Do not use the Proximity Sensor underwater, outdoors or in the rain.
Operating Environment
Be sure to use the Proximity Sensor within operating ambient tem-
perature range and do not use the Proximity Sensor outdoors so
that its reliability and life expectancy can be maintained. Although
the Proximity Sensor is water resistive, a cover to protect the Prox-
imity Sensor from water or soluble machining oil is reco mmended
so that its reliability and life expectancy can be maintained. Do not
use the Proximity Sensor in an environment with chemical gas (e.
G., strong alkaline or acid gases including nitric, chromic, and con-
centrated sulfuric acid gases).
