Caution

Item

Examples

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).
